Problem on R when creating a PCA plot
A very weird thing is happening to me on R, the first time i installed “ggfortify” pacakage to create a PCA plot, the result was an Rplots.pdf file, it worked perfectly. The second time i used it, with the same exact data and commands, the result is an empty Rplots.pdf file and continues to happen every time i try to run R.
Can someone tell me what is the problem?
I used the following commands in R:
library(“ggfortify”)
q<-read.table(“result_file_PCA.rel”,head=F)
q2<-read.table(“file1.clst”,head=T)
autoplot(prcomp(q), data = q2,colour=”CLUSTER”)
Thank you very much for your help.
