Hello
Would anyone be able to direct me to information on how to perform a straightforward Principal Components Analysis in r?  Including the data file set-up?  

I'm rather new to r and not having much luck.
I'm pretty certain I have the data entered into the txt file properly but when I try to follow some of the examples online I receive a number of errors in r that I don't understand.
Any help would be greatly appreciated.
thanks
Mark
