Hi Ony, If you got a data.frame with dfCorTFandPCA=as.data.frame(corTFandPCA) so you can try something like:
orderedCorTFandPCA=dfCorTFandPCA[order(dfCorTFandPCA$PC1),] May be you can also try force PC1 to be numeric with:. orderedCorTFandPCA=dfCorTFandPCA[order(as.numeric(as.character(dfCorTFandPCA$PC1))),] Good luck milton brazil=toronto On Wed, Jun 17, 2009 at 11:16 PM, onyourmark <william...@gmail.com> wrote: > > Hi.
