[Rd] An inconsistency in docs for file.access(base)

2009-02-15 Thread Keith Satterley
I was chasing a "no permission to install to directory" error message. I was looking in the code for /R/trunk/src/library/tools/R/install.R which pointed me to the file.access function. On reading the help for this function, it has the following in the Details section: The mode value can be t

I think something like this would be very useful. I'm sure you know of NIST's Guide to Mathematical Software (GAMS). It looks like they list places to find things, but it is clear some of that is proprietary (IMSL, NAG), some is on NETLIB but seems to have embedded copyright statements. (I once

[Rd] S4 structure classes and Ops methods

2009-02-15 Thread John Chambers
The methods package has methods for group generic "Ops" for S4 classes that extend "array", "structure" or "vector". The methods mainly try to produce a consistent result when structures and vectors are combined. See class?structure, section "Methods". In the development version of R committ

[Rd] Load/Save files for tk GUI

The Windows GUI version of R has menu items that allow load/save of workspace and history. Attached is a proposed patch to tkGUI.R to give the same capabilities for Linux users using the tk GUI. (Penguins need love too.) http://www.nabble.com/file/p22026168/tkGUIpatch.tgz tkGUIpatch.tgz -- Vie

Ben Bolker gives some reasons why Numerical Recipes may be problematic as a starting point for R codes. CUP did a masterful job of marketing, but the license is restrictive as the links he gives points out. In some tests, I've also noted that some of the algorithms are less than stellar e.g, conver
