R is a programming language for statistical computing and data visualization. It has been adopted in the fields of data mining, bioinformatics and data analysis. [9] The core R language is augmented by a large number of extension packages, containing reusable code, documentation, and sample data. R software is open-source and free software.
R packages are extensions to the R statistical programming language. R packages contain code, data, and documentation in a standardised collection format that can be installed by users of R, typically via a centralised software repository such as CRAN (the Comprehensive R Archive Network).
The offer of a so-called Knuth reward check worth "one hexadecimal dollar" (100 HEX base 16 cents, in decimal, is $2.56) for any errors found, and the correction of these errors in subsequent printings, has contributed to the highly polished and still-authoritative nature of the work, long after its first publication.
Objective-C is a high-level general-purpose, object-oriented programming language that adds Smalltalk-style message passing (messaging) to the C programming language. [3] Originally developed by Brad Cox and Tom Love in the early 1980s, it was selected by NeXT for its NeXTSTEP operating system .
Swift won first place for Most Loved Programming Language in the Stack Overflow Developer Survey 2015 [36] and second place in 2016. [ 37 ] On December 3, 2015, the Swift language, supporting libraries, debugger, and package manager were open-sourced under the Apache 2.0 license with a Runtime Library Exception, [ 38 ] and Swift.org was created ...
Turbo Pascal is a software development system that includes a compiler and an integrated development environment (IDE) for the programming language Pascal running on the operating systems CP/M, CP/M-86, and MS-DOS. It was originally developed by Anders Hejlsberg at Borland, and was notable for its very fast compiling.
The dash is a punctuation mark consisting of a long horizontal line. It is similar in appearance to the hyphen but is longer and sometimes higher from the baseline.The most common versions are the en dash –, generally longer than the hyphen but shorter than the minus sign; the em dash —, longer than either the en dash or the minus sign; and the horizontal bar —, whose length varies ...
Perl borrows features from other programming languages including C, sh, AWK, and sed. [1] It provides text processing facilities without the arbitrary data-length limits of many contemporary Unix command line tools. [16] Perl is a highly expressive programming language: source code for a given algorithm can be short and highly compressible. [17 ...
