Hello! I am using R 2.5.0 under Ubuntu 6.06, and I am not an expert. Recently, I think from the latest update some warning messages started to appear, when I use my old data-file and R-histories (hence, everything was done before and worked perfectly well). It seems to me that those are related to the Design package, but I am not sure. One is coming out after:> d = datadist(a,b,c)Warning message: $ operator is deprecated for atomic vectors, returning NULL in: X[[1]]$terms And the other after using ols() or lrm() etc.: Warning messages: 1: use of storage.mode(x) <- "single" is deprecated: use mode<- instead (this one is repeating: 2, 3, 4 times) What I do wrong? Could you help me? I realized that there were some important changes in the newest realises, and that some of them are, probably, related to the above warnings, but still I would like to have an explanation and an advice how to fix if something is wrong. Thanks in advance, PM
