HI, While I testing some code, I found some problem on Union handling. I've wrte following test code, and it has union assignment. The code's output is from pointerToUnion: chars mystring, length 64 from original: chars mystring, length 8000 It's caused by second char member(charlength) of LongestMember. For union assignment, llvm-backend seems generates assigning each member of

I can not provide a self-contained example, since I need an advice on this current dataset and its ?contradictory? results. So.... i have a dataset which contains 1309 cases and 11 variables, highly right-skewed and heavily zeroinflated (with over 1100 cases that have 0 value

I have the following code, from which I get the following error message: Error in dim(data) <- dim : attempt to set an attribute on NULL I think the error is coming from the part of my code in BOLD RED. The script works fine until then. #Load libraries source("http://bioconductor.org/biocLite.R") biocLite() library(limma) library(Biobase) #change directory to folder where
