Hi,
I am a beginner with R. I would like to get a loading plot of PC 3
vs PC 1.
For PC 1 vs PC 2 I use
library(pls)
loadingplot(pca.result, comps = 1:2, scatter = TRUE, labels="names")
if I try
loadingplot(pca.result, comps = 1:3, scatter = TRUE, labels="names")
I get the loading plots of PC 1 vs PC 2, PC 1 vs PC 3 and PC 2 vs PC
3. What
do I have to do to get just a single loading plot of PC 3 vs PC 1.
