file.rename overwrites existing target (PR#14065)
Full_Name: Jens Oehlschl?gel
Version: 2.10.0
OS: Windows XP Professional
Submission from: (NULL) (85.181.158.112)
file.rename() will successfully rename file a to b - even if b exists already.
Though the documentation does not state what file.rename() will do in this
case,
I guess the expected behaviour is to fail and return FALSE.
Kind regards

Summary: How to represent pure linefeeds chr(10) under R for Windows
Thanks to all who have responded.
My concern was to be able to write a csv file that can have line feeds in
string columns chr(10).
Why? Excel allows line feeds chr(10) within cells and line breaks
chr(13)+chr(10) at line ending,
but the windows version of R automatically replaces \n by \r\n in writing
and \r\n by \n in reading (text mode).
The clues for a solution came from Brian Ripley and

problems with assigning a class to an environment
I was surprised to find that calling str() on an environment can remove
attributes from it, as in
> a <- new.env()
> class(a) <- "jens"
> class(a)
[1] "jens"
> str(a)
Class 'jens' length 0 <environment>
> class(a)
NULL
then I found in the R-Language-Manual in chapter 2.1.10 Environments the

How to return a big treelike list from .Call Interface (protect stack overflow)
I try to create a big treelike list structure using the RDefines/RInternal
macros. The tree carries information at each node (attribute list) and at each
leaf (vector).
My understanding is that for each node I add to the binary tree I have to
call
PROTECT(newnode = NEW_LIST(2));
and cannot UNPROTECT before I return the whole tree. Same story for node
attributes and leaf vectors. However, this

Dear John,
Dear Joseph,
Thank you for your quick answers and the pointer to semnet.
I try to clarify on my assumptions:
- yes, I am willing to assume multivariate normality
- no, I don't want to assume a single factor model
- I assume there is an unknown number of factors, and I do not know which
items belong to which factors
but I still want to estimate single item reliabilities

How to grow an R object from C (.Call Interface)
What is the best way to grow an R return object in writing a C function
using the Rdefines.h macros.
In my application, the final size of the return object is not known during
construction. My understanding is that each time I grow an R object I have to
use PROTECT() again, probably before UNPROTECTing the smaller version.
However, due to the stack character of the PROTECT mechanism, UNPROTECT
