I have been working with R extensively for several months. I switched from SAS and Matlab to R. My question is Can anyone explain the benefits and detractions of the 'Date' package verses the 'date' package and verses 'POSIX' dates. I have noticed several other packages use one or the other. Rmetrics seems to standardize on POSIX. I can only see differences in

I just installed RMySQL 0.5-9 with R 2.4.0 on Windows XP and got the following error message when trying to run a script with RMySQL: Error in library(RMySQL) : 'RMySQL' is not a valid package -- installed < 2.0.0? Any ideas? Thanks, Frank

Hi all, I would greatly appreciate some help understanding how R references arrays, matrices, lists, and objects using [[]] and []. I have read the R guides and several tutorials but I am not the fastest kid on the block so I am still having difficulty understanding this. For examples the following code produces a 5 element list of 2X5 random numbers that I then convert to a 2X5X5 matrix.

All, Is there a way to add comment blocks in an R script other than using # at the beginning of each line? Or, is there anything like ndocs for C++ and the markup for Java that can generate documentation? This may be a bad question, but I have searched R documentation and can't seem to find an Answer. I have also looked at the R package documentation mark up docs for help files but

Hi R users, I am unable to load RMySQL. The zip file is not available which I guess is needed to load this pakage. I also tried extracting the package from RMySQL_0.5-11.tar.gz and then pasted the package in the directory where R is loaded for which I am getting the following error message "Error in library(RMySQL) : 'RMySQL' is not a valid package -- installed <

I was trying to email directly the developer, David A. James, but all the emails bounce... Does anyone know if RMySQL may be re-compiled under Windows and what are the limitations?

I have been reviewing the arch test of vars package that is based on Engle's paper. R-metrics has this as a wants/todo item. I need an arch test and thought I might accomplish two things at once or at least try. The arch test requires a varest object and I am trying to write one that will use R-metrics arima, arch, Garch objects, or at least a vector. Also the arch function has the
