There should be no reason not to be possible, if the notebook uses an
OS that R supports.

I wrote the following lines of codes try to do some iterations to find the

Dear Sir/Madam,
I converted the .dta into .Rdata with the foreign library read.dta. However,
when I use fix() I get the message that the dates are discarded.
Before fix(), class(dateX) gives 'dates' as class; after fix() class(dateX)
gives 'character'
Why is that?

One way is to give the names you want to use as the rownames of the scores
component of the principal component analysis object. e.g.

rownames(pca$scores) - paste(C, substring(1001:1150, 2), sep = )
