Hi all, Thanks to Dr Paul Murrell in New Zealand to remind me of security consideration. I am releasing version 0.2 with security fix. This version will allow you to add banned R function names in a list. R_PHP_Online is a PHP CGI web interface to run R programs online, with the capability to show graphics online.

...many examples of R/S-Plus outputs but no explanations of meaning. I am afraid this turns out to be a silly and unworthy question. Would anyone be kind enough to show relevant literature or a text book to a layperson studying on his/her own? Thanks in advance. -- Yukihiro Ishii <yukiasais at ybb.ne.jp>

Over the years I have noted a couple of people interested in an R package that will read tiff files. There were some valid arguments against (e.g. R is not an image editting suite, libtiff does not support all tiff files, etc.). True enough, when I want to work with family photos, I use Gimp. But in my research I use tiffs as data sets in the context of computational biology and molecular

Hello. R's e1071 package has "allShortestPaths" function using Floyd's algorithm. It is very useful for road network analysis. I'll try to analyze facility allocation programs using this. I'd like to know how much nodes this function can deal with? And for larger nodes(for example million nodes), allShortestPaths employs graph partition algorithm? Regards.
