...rts lately about segfaults in the rgl package. I've only been able to reproduce these on Linux. I am not so familiar with C++ details, so I have a couple of questions way down below. But first some background info. One recipe to recreate the crash works with a new version 5.0-1 of the mixOmics package: > library(mixOmics) > example(pca) This crashes with messages like this: Program received signal SIGSEGV, Segmentation fault. 0x00007ffff28aafd9 in __exchange_and_add (__mem=0x7f7fffff7f7ffff7, __val=<optimized out>) at /usr/include/c++/4.7/ext/atomicity.h:48 48...

Hello, I would like to perform a Partial least square discriminate analysis (PLSDA) in R. To do this I use the package mixOmics. I could perform the PLSDA in R. however I would also like to perform a leave-one-out cross validation in order to assess the performance of my model. My supervisor told me that I should focus on the R2/Q2 ratios. However when I read the instruction for running the "perf" function (m...

Hello all, Is there any function in R by which I can calculate PRESS and P2 statistics for linear regression in R? Thanks Alex [[alternative HTML version deleted]]
