Hello everyone,
R beginner, I am confronted with the need to use
Rmpf.
It helps to provide a sensible subject line and not to misspell package
names:Rmpfr.
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 <- mpfr(M1, precBits = ....)
M1%*%M2
Should work out of the box for mpfr objects.
scale(M1,TRUE,FALSE)
There is not scale function implemented in Rmpfr. HEnce you need to
write it yourself based on the provided infrastructure from the Rmpfr
package.
Best,
Uwe Ligges
