Hi, 1- How can I assign different colors to different observations in the PCA chart? Assume, I have 10 observations and I want to use black color for the first 5 and read for the next 5 observations. Currently, I use ?res.pca = PCA(mydata[,1:37], scale.unit=TRUE, graph=T) ?plot(res.pca,axes=c(1,2)) 2- How can I change the plot area size and font sizes? With these commands ?dev.new(width=20, height=4) ?plot(res.pca,axes=c(1,2)) The final plot is not what I expected. Please see the picture at?https://imgur.com/UINTnv7
No need to post twice. You probably didn't get an answer the first time because it was just an hour ago, and you didn't include "mydata" (or a suitable subset) in your posting. For the best chance at getting a helpful answer, post code that others can run. Duncan Murdoch
