okay so fixed what i need to do this way finit=0 for(ri in 1:dim(xa)[1]) { finit=finit+1 xc[ri,1:finit]<-xa[ri,1:finit] xc[1:finit,ri]<-xb[1:finit,ri] }
but getting error in heatmap.2 > mycol <- colorpanel(n=40,low="red",mid="white",high="blue") > heatmap.2(xc, breaks=pairs.breaks, col=mycol, Rowv=FALSE, symm=TRUE, > key=TRUE, symkey=FALSE, density.info="none", trace="none", cexRow=0.5, + scale = "none", dendrogram="none") Error in heatmap.2(xc, breaks = pairs.breaks, col = mycol, Rowv = FALSE, : `x' must be a numeric matrix any pointers are appreciated -- View this message in context: http://r.789695.n4.nabble.com/correlation-matrix-tp3891085p3891584.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
