R (“GNU S”) is an environment and a language for dealing with statistical graphics and computing.
R is a complex suite of useful tools for manipulating data, making calculations and displaying the results graphically.
R includes numerous and efficient statistical and graphical techniques ( statistical tests, linear and nonlinear modelling, time series analysis, classification, clustering and more).
Here are some key features of "R":
· An effective data handling and storage facility,
· A suite of operators for calculations on arrays, in particular matrices,
· A large, coherent, integrated collection of intermediate tools for data analysis,
· graphical facilities for data analysis and display either directly at the computer or on hardcopy
· A well developed, simple and effective programming language (called `S') which includes conditionals, loops, user defined recursive functions and input and output facilities.
· X11 system manager (optional).
· Gnu g77 compiler and tcltk libraries included with the installer.
What's New in This Release: [ read full changelog ]
· chooseCRANmirror() and chooseBioCmirror() gain an ind argument (like setRepositories()).
· mcparallel has a new argument mc.interactive which can modify the interactive flag in the child process. The new default is FALSE which makes child processes non-interactive by default (this prevents lock-ups due to children waiting for interactive input).
· scan() now warns when end-of-file occurs within a quoted string.
· count.fields() is now consistent with scan() in its handling of newlines in quoted strings. Instead of triggering an error, this results in the current line receiving NA as the field count, with the next line getting the total count of the two lines.
· The default method of image() will plot axes of the class of xlim and ylim (and hence of x and y if there is a suitable range() method). Based on a suggestion of Michael Sumner.
· load() now has a verbose argument for debugging support, to print the names of objects just before loading them.
· When loading a serialized...
