I have an exercise. With 3 kinds of yohourt a,b,c. There are 25
participatients estimate 3 norms: taste (va,vb,vc), structure (ca,cb,cc) and
price (ga,gb,gc) and give the mark from 1 to 5. I don't know how to PCA this
data. Please help me!
I attached the data file follow:

Dear Ms/Mr,
In a package, I want to use PCA function. The structure I used follow this
page: http://www.statmethods.net/advstats/factor.html.
fit<-principle(mydata, nfactors=9, rotation=TRUE)
or:
result<-PCA(mydata)
But I don't known why R language in my computer noticed: "not fou
This is a homework problem. I know how to do a PCA, you need to learn.
I suggest you visit your textbook, then check the documentation for R's
various PCA implementations to work out how to effect the analysis.

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
