History[edit]
'Old S'[edit]
S is one of several statistical computing languages that were designed at Bell Laboratories, and first took form between 1975–1976.[2] Up to that time, much of the statistical computing was done by directly calling Fortran subroutines; however, S was designed to offer an alternate and more interactive approach. Early design decisions that hold even today include interactive graphics devices (printers and character terminals at the time), and providing easily accessible documentation for the functions.
The first working version of S was built in 1976, and operated on the GCOS operating system. At this time, S was unnamed, and suggestions included ISCS (Interactive SCS), SCS (Statistical Computing System), and SAS (Statistical Analysis System) (which was already taken: see SAS System). The name 'S' (used with single quotation marks until 1979) was chosen, as it was a common letter in the suggestions and consistent with other programming languages designed from the same institution at the time (namely the C programming language).[2]
When UNIX/32V was ported to the (then new) 32-bit DECVAX, computing on the Unix platform became feasible for S. In late 1979, S was ported from GCOS to UNIX, which would become the new primary platform.
In 1980 the first version of S was distributed outside Bell Laboratories and in 1981 source versions were made available.[2] In 1984 two books were published by the research team at Bell Laboratories: S: An Interactive Environment for Data Analysis and Graphics[3] (1984 Brown Book) and Extending the S System.[4] Also, in 1984 the source code for S became licensed through AT&T Software Sales for education and commercial purposes.
'New S'[edit]
By 1988, many changes were made to S and the syntax of the language. The New S Language[5] (1988 Blue Book) was published to introduce the new features, such as the transition from macros to functions and how functions can be passed to other functions (such as apply). Many other changes to the S language were to extend the concept of 'objects', and to make the syntax more consistent (and strict). However, many users found the transition to New S difficult, since their macros needed to be rewritten. Many other changes to S took hold, such as the use of X11 and PostScript graphics devices, rewriting many internal functions from Fortran to C, and the use of double precision (only) arithmetic. The New S language is very similar to that used in modern versions of S-PLUS and R.
In 1991, Statistical Models in S[6] (1991 White Book) was published, which introduced the use of formula-notation[7] (which use the '~' operator), data frame objects, and modifications to the use of object methods and classes.
S4[edit]
The latest version of the S standard is S4, released in 1998.[8] It provides advanced object-oriented features. S4 classes differ markedly from S3 classes; S4 formally defines the representation and inheritance for each class, and has multiple dispatch: the generic function can be dispatched to a method based on the class of any number of arguments, not just one.[9]

The Smith & Wesson K-38 Combat Masterpiece, Revolver Model 15 is a six-shot double-actionrevolver, with adjustable open sights, built on the medium-size 'K' frame. It is chambered for the .38 Specialcartridge and is fitted with a 4-inch (100 mm) barrel, though additional barrel options have been offered at various times during its production. Originally known as the 'K-38 Combat Masterpiece', it was renamed the Model 15 in 1957 when all Smith & Wesson revolvers were given numerical model numbers. It is a shorter barrel version of the Smith & Wesson Model 14 Target Masterpiece and essentially an adjustable-sight version of the seminal Smith & Wesson Model 10 ('Military and Police') revolver with target shooting features. The main production run of the Model 15 was from 1949 through 1999. It was discontinued for approximately a decade until 2011, when a re-tooled version was re-released under S&W's Classics Revolvers line.
History[edit]
The Smith & Wesson K-38 Combat Masterpiece Revolver Model 15[1] is a derivative of the classic 1899 K-frame (medium frame) Military and Police .38 S&W Special (aka .38 Special) six-shot double-action revolver. The M&P underwent steady evolution throughout the 20th century and S&W spun off several variations as separate models in the post World War II years. One of these was the K-38 Target Masterpiece, which began production in 1947. The Target Masterpiece included a number of new and/or special features, including a six-inch barrel with a narrow rib to provide a level sight plane, a Patridge front sight, a micrometer click rear sight, S&W's .375' short-throw hammer, a trigger adjustment for overtravel, and improved grips.[2] Noting the accuracy of the Target Masterpiece, a number of police departments and the FBI soon requested the same revolver with a four-inch barrel and a Baughman Quick Draw front sight. The result was the K-38 Combat Masterpiece. The major distinction between the K-38 Target Masterpiece and the K-38 Combat Masterpiece is the barrel length and the front sight.[2]
In 1957 the K-38 Combat Masterpiece was renamed the Model 15 when all Smith & Wesson revolvers were given numerical model numbers. (The Military & Police and the Target Masterpiece were renamed the Model 10 and Model 14 respectively.) The model number is stamped on the frame behind the cylinder yoke, so it is visible (only) when the cylinder is open. A number of production and engineering changes have been made throughout the years, some of which are noted by a dash number suffixed to the Model number (15-1, -2, -3).
Over the years the Model 15 has been produced with several barrel lengths, with 4' (standard) and 2' (1964–1988) being the most common. In 1972 S&W released a stainless steel version as the Model 67. In 1997 the hammer and internal lockworks were modified from an on-the-hammer firing pin / internal hammer block to a floating firing pin / MIM flat hammer, and kept the hammer block that, unlike a transfer bar safety design, moves up with the trigger pull. The hammer hits a transfer bar, transferring the strike to the firing pin, while the block in a hammer block system moves down with the trigger pull, unblocking the hammer from the firing pin, allowing the hammer to strike the firing pin. These two safety systems work oppositely, but achieve the same goal of only allowing the gun to fire when the trigger is pulled all the way.
The Model 15 was a popular sidearm for law enforcement and was the standard-issue sidearm of the U.S. Air Force Police from 1962 until 1992 when it was replaced by the Beretta M9 pistol.[citation needed]
Production of the Model 15 was discontinued in 1999 when Smith & Wesson was purchased and reorganized, although a couple limited run 'Heritage Series' models were released in 2001 and 2002. In 2011 Smith & Wesson re-introduced the Model 15 (15-10) under their Classics Revolvers line, newly machined, with a shrouded redesigned barrel, and a built-in trigger lock (located just above the cylinder release thumbpiece on the left side).[2]

Military and police usage[edit]
As the 'K-38 Combat Masterpiece', this revolver was first purchased in 1956 for the Strategic Air Command Elite Guard of the United States Air Force. From 1960 to 1969 the Air Force bought large numbers of Model 15-1, 15-2, and 15-3 revolvers with a 4' barrel. The only distinctive markings are 'U.S.A.F' on the left side of the frame. Originally all were blued, though some were reparkerized while in Air Force service.[2] The Model 15 was the standard issue sidearm of the U.S. Air Force Air/Security Police from 1962 until 1992. It was issued to security personnel in other branches of the U.S. armed forces, including the Naval Security Forces.[2]

The Air Force issued two types of .38 Special duty ammunition for the Model 15, originally the M41 .38 Special Ball (full metal jacket) cartridge, or the later-developed Caliber .38 Special, Ball, PGU-12/B High Velocity cartridge. The M41 was a low pressure cartridge rated at 13,000 psi, originally designed for 158-grain ball ammunition, but loaded with a 130-grain FMJ bullet. The PGU-12/B, issued only by the U.S. Air Force, had a greatly increased maximum allowable pressure rating of 20,000 psi, sufficient to propel the 130-grain FMJ bullet at 1,125 ft/s (343 m/s) from a solid 6-inch (150 mm) test barrel, and 950–980 ft/s (290–300 m/s) from a 4-inch (100 mm) revolver barrel.[4]
The S&W Model 15 revolvers were replaced by the Beretta M9 pistol in 9×19mm caliber beginning in 1985, with complete turnover by the early 1990s.[2]
In addition to military use, the Model 15 was issued by many police departments across the United States as well as various federal law enforcement agencies.[2] In 1972 S&W produced a stainless steel version of the Model 15 which it termed the Model 67.[2]
Users[edit]
The LAPD's Model 15 revolvers (and department issued Model 36 5-shot, 2-inch barrelled snub nose Smith & Wesson revolvers for detectives, plainclothes, undercover and other officers' off duty carry) were modified to be fired double-action only. This was accomplished by the department armorer who ground the full cock notch from the hammers. Officers were then trained to shoot combat style without ever cocking the weapons. This change was likely the result of unintended injuries and/or property damage, and of litigation against the LAPD after officers had cocked their weapons only to have them discharge inadvertently, possibly as a result of physical attacks or having been startled in the course of searching for suspects. In lawsuits, the principle of res ipsa loquitur was easily affirmed because 'an inadvertent weapon discharge is a negligent discharge'.[2]
Overland Park Police Department (Kansas) used the revolver before going to semi-automatic Beretta 92 pistols.
