Dear All, I learned about R during my studies at Cologne University of Applied Science. Now I work at Allianz Dresdner Bauspar AG and I would like to install R here too. Is there any license issues that need to be taken in consideration, any fees to pay by the company? I know there are answers to this in the FAQs but I didn't really understand the legal language. Could you therefore just give

As an end-user, I wonder about Revolution R. Is the relationship between Revolution R and the R community at-large a positive one? Do the former contribute to the development efforts of the latter? Is there a competitive aspect? is their forum competitive with r-help? any other thoughts? (most of all, I simply hope that they help some of the many helpful experts on this forum, who have

Oftentimes, I see graphs on the web that *look* like they've been produced by R, but I can never be sure. Or can I? I notice that PostScript files include a "%%%Creator: R Software" line, but do R graphics drivers encode any identifying information in GIF or PNG files more commonly used on the web? And of so, would such evidence necessarily be obliterated in post-processing (e.g

Hi All, would appreciate an answer on this if you have a moment; Is there a function (before I try and write it !) that allows the input of a covariance or correlation matrix to calculate PCA, rather than the actual data as in princomp() Regards Glenn [[alternative HTML version deleted]]

Hi everyone, Thanks for the help in advance. I just want to know if there is absolutely any way of using multicore if my loop can't run in parallel as each iteration depends on the previous iteration. I have Windows R 2.9.2 and REvolution R Enterprise 2.0 for Windows 64 bit. I also have if necessary R on Ubuntu. 8gb of ram and a core 2 duo processor but I could use a quad core as well. Many

I found the following document on making R packages. But it is old. I'm wondering if there is more current ones and hopefully more complete ones. http://biosun1.harvard.edu/courses/individual/bio271/lectures/L6/Rpkg.pdf

It runs more than twice as slowly using 8 core than using a single core in inverting large matrix.

There are now several R geographic user groups, and a few have mailing lists on the R mailing list system. Thanks to Martin M, there's also a pointer to a page I'm maintaining to list/describe the groups. The page is at http://macnash.telfer.uottawa.ca/RUG.html Contact me if you have a listing. I'm prepared to wikify it if there is sufficient interest. John Nash
