Dear Lorenzo,
This is the trade off that comes with convenience. The `$` operator
passes its argument directly as I understand it. This is what lets
you pass unquoted names that not variables. The way around it is to
use the `[` extraction operator. Look at these examples:

Let y be the hold out response values. Let y.hat be the model predictions

The key is to remember that R^2 = cor( y , y.hat )^2.
So,
cor( cbind(y,y.hat))[1,2]^2

Hello,
I have a two column dataframe that
has entries that look like this:
2315100 NR_024005,NR_024004,AK093685
2315106 DQ786314
and I want to change this to look like this:
2315100 NR_024005
2315100 NR_024004
2315100 AK093685
2315106 DQ786314
I can do this

Sorry about that; s <- 1

OK, I found the bug in subplot (it was never tested with multiple figures).
The bug has been fixed, but probably won't make it to CRAN any time soon. In
the meantime there are a couple of work arounds.
1. create your own local copy of subplot and edit it so that the 1st 3 lines of
the body ar

Well, not really ...
Google on "R package Debye" . The 5th hit lists the gsl package with
the debye() function.
Moral: DO make use of standard professional search tools, also.

Suppose I have the following data:
tmp <- data.frame(var1 = sample(c(0:10), 3, replace = TRUE), var2 =
sample(c(0:10), 3, replace = TRUE), var3 = sample(c(0:10), 3, replace = TRUE))
I can run the following double loop and yield what I want in the end (rr1) as:
library(statmod)
Q <- 2
b <- runif

Suppose I have a data file (possibly with a huge number of columns), where the
columns with factors are coded as "1", "2", "3", etc ... The default behavior
of
read.table is to convert these columns to integer vectors.
Is there a way to get read.table to recognize that columns of quoted number

library(sos)
Debye <- ???Debye
#found 4 matches

Conclusions:
1. There are references to Debye in the "CHNOSZ" package,
but it may not be what you want.
2.
Dear all
I am implement one grid computing system using GridR package. I am
working on windows platform. I did all the configuration according to
the GridR tutorial.
But it has some errors when I execute grid.apply function.
Here is the output from stderr:
R: not found
java.io.IOException: Error d
Dear list,
Is there another package than gsl* where the Debye function (of first order)
is implemented? Google only finds the gsl package.
Thanks in advance

Thanks to everyone who replied to my post. One person indicated that this
question treads on "dangerous terrain." I had that sense too but really wanted
to know how many packages might not be "free" in the sense that they could be
used at no cost by everyone. I was a little disappointed to learn
