Hi,
The "xtable" method for "summary.prcomp" is just creating a table of the
"importance" values. So you can get the same table for just a few of the PCs
by subscripting the importance values:
xtable(mySummary$importance[,1:2],digits=4)
Best,
Charlie

Subject: [R] xtable prcomp
Hi, I need to export to LaTex the summary of a PCA. So:
myPCA <- prcomp(myDF)
mySummary <- summary(myPCA)
#
print(xtable(mySummary))
How can I export to LaTeX not all the summary but only the first nPCs??
Best
Riccardo
