In general, if you have an nxn matrix, you can use the apply function to
apply a function to each row of the matrix, and return the result.
So, as a start, you could do,

I tried to select a mirror site from R, but got the following error -
chooseCRANmirror()
Warning message:
In open.connection(con, r) :
unable to connect to 'cran.r-project.org' on port 80.
The consequence is that i have to install R-packages by downloading zip
files one by one, and then

Hi Moshe,
Your idea sounds reasonable to me. It seems analogous to have a system of
linear equations with
more unknowns that equations - there should be several solutions so there is
no exact PCA solution.
My plan (* = dot product)
1. Pick first nice vector to be longest - that is x1 * x1 is

Hi everyone -- I have a number of systems here running CentOS 5.2 and
5.3. Recently, I tried adding a package unrelated to R and found that
yum is complaining about the R repo. Here's the error I get when
running yum update:

Have look in the ROCR package and Example's.

Hello,
Frank was nice enough to point me to the val.prob function of the Design
library.
It creates a beautiful graph that really helps me visualize how well my
model is predicting probabilities.
By default, there are two lines on the graph

2)
Thanks everyone for their replies, both on- and off-list. I should
clarify, since I left out some important information. My original
dataframe has some numeric columns, which get changed to character by
gsub when I replace spaces with NAs. Thus, in going back to a
dataframe, those (now
Dear All,
I am trying to fit a simple linear mixed model (see below this paragraph)
arising from a crossed factorial design with 2 factors and ubalanced number of
replicates (from two to five) in each cell, but I keep getting an error message
(see bottom of message). The model is:
yijk =
x - 1041281__2009_08_20_.lev
I would like to split this string up and only extract the leading numbers.
1041281
to use as a label for a data column in a bigger for loop function to
read in data.
regards,

This assume _ if the first character following the numbers. You may need a
character class if it can be one of several.
?gsub
?regex
for further (terse for the latter) details.

Actually _ is not a metacharacter so, gsub(_.*,,x) will do.
