anyone has C++ STL classes stability issue if used with R
Hello,
is there any one who uses C++ STL classes when programming shared libs
for R and has had any problems with STL?
In the very simple example below I am constantly getting segfaults when
trying to populate the queue. The segfault occurs at what looks like a
random index in the loop when pushing another element to the queue.
Reproduced on 4 machines. Object x is an Image as in EBImage,

R and Memory
I would suggest that you make a more thorough search of the R-Archives.
(http://finzi.psych.upenn.edu/search.html) If you do you will find this
discussion has been had several times and that the type of machine you
are running will have an impact upon what you can do. My feeling is that
you are going have to knuckle down with the documentation and understand
how R works and then when you have

Merge data frame with mispelling characters
Hello dear R-helpers,
I'm working with R-2.15.2 on Windows 7 OS. I'm stucked with a merge of two
data frames by characters.
In each data frame I got two different list of names, that is my main-key to
be merged.
To figure out what I'm saying, I build up a modified "?merge" example, with
errors by purpose:
# Data for authors:

write.dta (foreign package)
Hi,
I'd like to request that the 'write.dta' command also save the
"var.labels" attributes of the data frame.
'read.dta' can read them, but 'write.dta' doesn't write them back.
Thanks....

factanal question
Dear R users:
I'm wondering if it's possible to get the residual correlation matrix when using factanal.
Since factanal assumes that the errors are normally distributed and independent (provided the factor model fits the data) this would be useful. Of course you would need to submit the data to the function to get the residuals (not just their correlation matrix), but it should be possible

Mac OS X crash bug?
Hi all,
I want to check if this is a bug for which I should file a report.
I am using R2.5.0 on OS X 10.4.9. When I invoke the data editor and
when I change the values of individual cells, it seems to work as
intended. However, when I try to delete/add a row/column, R.app
crashes. I've attached the crash log.

sas.get problem
I have 3 SAS files all in the directory F:/sas, two
data files
and a format file :
form.ea1.sas7bdat
form.ea2.sas7bdat
sas.fmts.sas7bdat
F is a USB.
I am trying import them to R using "sas.get".
I have not used SAS since I was downloading data from
mainframe
and having to write JCL. I had forgotten how bizarre
SAS can be.
I currently have not even figured out how to load the

retain class after merge
Dear All,
is there a simple way to retain the class attribute of a column, if
merging two data.frames?
When merging the example data.frames form help(merge) I am unable to
keep the class attribute as set before merging (see below).
Two columns are assigned new classes before merge (myclass1,
myclass2), but after merge the resulting column has class "character".
best regards,
