problem with loadURL -- claims newer version used
Dear list,
I am trying to prepare a handout showing how to use R for factor
analysis. As part of the exercise I want to save a correlation
matrix on a tutorial web page. I can save with no problem (saving
locally and then transferring to the web site). Although I can
load() the local file, I am having problems getting loadURL to read
the remote file. I have tried saving it as an ascii

Comment on loadURL: should default to mode="wb"
So the help for loadURL says:
'loadURL' is a convenience wrapper which downloads a file, loads
it and deletes the downloaded copy.
Trying to load an rda file on Windows (XP, R-devel) I was surprised
when I received an error about input being corrupted with LF
replaced by CR.
The fix was to specify mode="wb" to loadURL. This gets passed to
download.file and the right

Inspect a "delayed" assigned whose value throws an error?
Hi, I got an interesting programming challenge:
How do you inspect an object which is assigned via delayedAssign() and
that throws an error as soon as it is "touched" (=the value is
evaluated)? Is it possible?
MINIMAL EXAMPLE:
$ R --vanilla
> delayedAssign("foo", stop("Hey!"))
(If you find this minimal example silly/obvious, please skip down to

If it was any other environment than the global, you could use substitute:
e <- new.env()
delayedAssign("foo", stop("Hey!"), assign.env = e)
substitute(foo, e)
delayedAssign("foo", stop("Hey!"))
substitute(foo)

I am wondering how to make a function Fun to make the following work:

SVM? Comparison method wanted: 3 Groups, Microarray data
Dear all,
i have microarray data of 3 classes of patients. It's not a time course experiment only steady state.
I used a rule-based method to classify the groups by the expression of the genes. This works out so far. Nevertheless I want to check my results with an other method. Therefore I look for one and want to ask you, what you suggest.

Hi,
Plotting a graphic into a postscript device using family="mono" returns the

Thanks guys for your help.
