With the same system configuration (WinNT4 SP6 and 1.7.0), I get such a Dr Watson crash each time I try to use the Change dir... command in the File menu of Rgui.exe. I doesn't seems to happen if I do this immediately after starting R but well if I already did some computation. I don't have any problem by using directly setwd().

This is already corrected in R-patched (April 22 is a long time ago in R terms).

R users As was mentioned before, the princomp() function in R 1.7.0 will complain if the data set has more columns than rows. The alternative functions to generate a PCA analysis that will not complain about such type of data set are prcomp() or pca() (multiv library). Although the results of both of them are almost identical, the outputs are not compatible with the biplot() function from mva. Does anybody know if there is an alternative way to generate the biplot?? I can generate a two dimensional graph with the sample scores by plotting the values from the object where the results are, but how do I plot the arrows that represent the loadings??? thanks Hector ******************************************** H?ctor L.
