Hello, I encountered a strange problem. When I executed the same code in R-windows and in R-linux, the resulted heatmaps have the exact same figure(clustering), but for the x-axis label the order of the duplicates are reversed (the sample orders are the same). For example, R-windows: sample1-R1, sample1-R2, sample2-R2, sample2-R1 R-3.1.1 R-linux: sample1-R2, sample1-R1, sample2-R1, sample2-R2 R-3.1.0 on HPC server Can anyone provide any suggestions to check the problem? Thank you very much! Thanks, Xiayu [[alternative HTML version deleted]]

Hi Xiayu, This isn't really a Bioconductor question, as gplots is a CRAN package. So you should really be asking on R-help. But I get identical results running this code on Linux and Windows: library(gplots) set.seed(0xabeef) mat <- matrix(rnorm(400), ncol = 4) colnames(mat) <- paste0("sample", rep(1:2, each=2), "-", rep(c("R1","R2"), 2)) heatmap.2(mat, cexCol = 0.7, margins = c(5,10)) Best, Jim On 7/24/2014 5:59 PM, Rao,Xiayu wrote: > Hello, > > I encountered a strange problem.
