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

Hi List, I am looking for an R advanced programming course in USA for April. Need to attend the course before April 31st. Regards - Steve [[alternative HTML version deleted]]

Hello Everyone,   I have just started learning R and am in the process of figuring out what it can and can't do. I must say I am very impressed with R so far and am amazed that something this good can actually be free.   Recently, I finished reading R for SAS and SPSS Users and have begun reading SAS and R and Data Manipulation with R. Based on what I've read in these books and elsewhere,

Dear All,   thanks to Berend, my question posted yesturday was solved succesfully here: http://r.789695.n4.nabble.com/hep-on-arithmetic-covariance-conversion-to-log-covariance-td4646068.html . I posted the question with the assumption of using the results with rlnorm.rplus() from compositions. Unfortunatelly, I am not getting reasonable enough outcome. Am I applying the results wrongfully? The example: I have known means and cov matrix of a multivariate distribution as follows:   sigma <-matrix(c(0.0037,-0.0001,-0.0370,-0.0136,0.0026,-0.0001,0.0001,0.0008,-0.0015,...

Hi all - has anyone ot and experienced problems with R+. Have downloaded the trail and it will not work -does it need vista (like it says on the box!) Thanks glenn [[alternative HTML version deleted]]

Hi, from what I understand about the canonical correlation function 'cancor', it looks for correlations in two sets of variables, each represented in matrix form. Right? Sounds exactly like what I need. I have tried the following but I am not sure how to interpret the results. AudioPCs <- c(ArTHarF0PCA$x[,2], ArTHarF1PCA$x[,2], ArTHarF2PCA$x[,2], ArTHarF3PCA$x[,2],

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
