Hi, I'm new to R and I'm finding it quite a chore trawling through the R documentation to find a function to carry out simple atomic tasks. Is any one aware of R help documentation that is aranged in functional categories for e.g.: String manipulation File I/O Dataframe, List manipulation etc, etc ... Thanks _________________________________________________________________ Get Hotmail on your mobile phone http://www.msn.co.uk/msnmobile
That's usually what help.search() is for.

Several people replied with ways to search the help, but that assumes you know the specific task you want to perform, and the right "keyword" to describe it. Beginners often just want to learn what's available. For a few functional categories there are "general" help pages, and you might not easily stumble across them. Here's a list I came up with recently. Just type e.g. "?Arithmetic" at the R prompt to learn about Arithmetic Operators. ?Arithmetic ?Comparison ?Control ?DateTimeClasses ?Defunct ?Deprecated ?Devices ?Extract (same as ?Subscript) ?Foreign ?Logic ?Memory ?Paren ?Rdconv (RdUtils page: Rdconv, Rd2dvi, Rd2txt, Sd2Rd) ?Special (beta, gamma, choose, ...) ?Startup ?Syntax ?build (PkgUtils page: R CMD build, R cmd check) ?connections (file, pipe, ...) ?pi (Constants page: LETTERS, letters, month.abb, month.name, pi) -- -- David Brahm (brahm at alum.mit.edu)

This starts the HTML help system. Follow the link to "Search engine and keywords". This works as long as you have an HTML browser configured. Duncan Murdoch
