[EXTERNAL] Re: NOTE: multiple local function definitions for ?fun? with different formal arguments
Because functions get called and therefore, the calling sequence matters. It?s just protecting you from yourself, but as someone pointed out, there?s a way to silence such notes.

[EXTERNAL] Re: NOTE: multiple local function definitions for ?fun? with different formal arguments
Here's a dummy example that I think illustrates the problem:
toto <- function() {
if (runif(1) < 0.5)
function(a) a
else
function(a,b) a+b
}
> fcn <- toto()
> fcn(1,2)
[1] 3
> fcn <- toto()
> fcn(1,2)
[1] 3
> fcn <- toto()
> fcn(1,2)
Error in fcn(1, 2) : unused argument (2)
How can you use the returned function, if you get different arguments?

Thanks. Workarounds are interesting but... what's the point of the NOTE

question on using "gl1ce" from "lasso2" package
Hi,
I tried several settings by using the "family=gaussian"
in "gl1ce", but none of them works.
For the case "glm" can work.
Here is the error message I got:

,data=iris,family=gaussian())
> gl1ce(Petal.Width~Sepal.Length+Sepal.Width+Petal.Length

LME: internal workings of QR factorization
Hi:
I've been reading "Computational Methods for Multilevel Modeling" by Pinheiro and Bates, the idea of embedding the technique in my own c-level code. The basic idea is to rewrite the joint density in a form to mimic a single least squares problem conditional upon the variance parameters. The paper is fairly clear except that some important level of detail is missing. For

can someone help me understand LAM/MPI and Rmpi for use on a cluster
I'm fairly astute at C and R but new to parallelization. Would someone
be willing to provide help in the form of a simple example that parallelizes
an R function from the inside of a C routine?
If so, write me back at izmirlig at mail.nih.gov
Thanks!

Cross-validation for logistic regression with lasso2
Hello, I am trying to shrink the coefficients of a logistic regression for a
sparse dataset, I am using the lasso (lasso2) and I am trying to determine
the shrinkinage factor by cross-validation. I would like please some of the
experts here to tell me whether i'm doing it correctly or not. Below is my

Help with functions
Hi there,
I have a the following function which takes a name(fname), total number of
rows (Total), number of times to make a sample(nSample), number of
records/rows to be included in each sample(nPatient). then it generates
required samples and calculates the mean and standard deviation of the
columns for each sample and finally in calculates the grand mean and
standard deviation.

Latest (as of a month ago) R under cygwin64. I'm teaching an intern package

In the package lasso2, there is a Prostate Data. To find coefficients in the

code is:

Please kindly advise if it is possible to
find the corresponding explanatory variable(s) for the model number.
