R help - Sep 2013 - no answer to the following question

I sent this message :
			Hello everyone,
			R beginner, I am confronted with the need to use
Rmpf.
			In my first scripts I made use of 
				X=read.table(file.choose(), header=FALSE,
sep=",",dec=".") 
				X=as.matrix(X)
			to load into a matrix data  from file before matrix
use.
			How can I do to load the same data in a
"mpfrMatrix".
			Is it possible to use with "mpfrMatrix" the same as
operations
				M1%*%M2 
				scale(M1,TRUE,FALSE)
			Sorry but I'm a newbe

			Thanks in advance

			Michel

But no body ... may be my question appear too simple for r-help people
I'll try alone using books
Thank you anyway

It helps to provide a sensible subject line and not to misspell package 
names:Rmpfr.

M1 <- mpfr(M1, precBits = ....)

Should work out of the box for mpfr objects.

There is not scale function implemented in Rmpfr. HEnce you need to 
write it yourself based on the provided infrastructure from the Rmpfr 
package.

You might be more successful if:

1. Post in plain text, not HTML, as the posting guide asks;

2. Don't post at all. Instead read the included tutorial, An Introduction
to R, or one of the many on the web that you might prefer. Nothing wrong
with being a newbie; but (imo, of course) there **is** something wrong with
being a newbie who has not first done some homework before posting to this
list.

Cheers,
Bert
