[R] Question regarding Principle Component Analysis and R for Windows

[Marcusdahl@aol.com]

Hi there,

I am a post-grad (Arts!) student trying to get to grips with R...

Though I am not statistically trained my research involves working with a 
large amount of numerical data currently held in Excel. I have been told by a 
Stats trained advisor that I should examine my data by some sort of 
Pricincipal Component Analysis.

My questions then are (all apologies if they seem simple but I am neither a 
programmer nor a mathematician)...

(1) Is there a way of moving all my data over from Excel into an R workspace 
or data folder.

(2) If I can get my data in R how do I start going about applying a 
priincipal component analysis to that data ( I have downloaded the PCA 
package from Professor Ripley's site)

(3) Is the 3D graphing package compatable with the PCA (mulivariate) package?


Sorry if these questions seem basic or too general but this all rather new to 
me (but I am keen to learn)

Cheers,

Marcus Dahl (Univ. Bristol English Dept.)
