please help with estimation of true correlations andreliabilities
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

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

> class(a) <- "jens"
> class(a)
[1] "jens"
> str(a)
Class 'jens' length 0 <environment>
> class(a)

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

mtext adj= wrong with several las= (PR#7188)
Dear all,
Our quite basic function mtext() does wrong adjustments in some parameter
configurations. This gets obvious when using multi line texts: There is no
way to properly adjust text perpendicular to axis 2, for example.

Error in substring: invalid multibyte string
Thanks for the quick response Ivan. readLines with encoding='latin1' works
for me (on Ubuntu).
However I was more concerned with the inconsistency in results between
substr and regexpr. I was expecting that if one of them errors because of
an unknown encoding then the other should as well. Even better, if regexpr
works, why shouldn't substr work as well?

package incompatibility under 2.5.0 (please respond directly, I am not on r-devel)
Dear all,
For my package "ref" I have implemented extensive regression testing. It now fails to compile since primitives "dim" and "dimnames" (and their assignment methods) no longer allow for additional arguments. I was using an additional argument "ref" with several methods. For "].refdata" it still works, with "dim.refdata" no longer.

Can someone point me to literature and/or R software to solve the following
problem:
Assume n true scores t measured as x with uncorrelated errors e , i.e.
x = t + e
and assume each true score to a have a certain amount of correlation with
some of the other true scores.
The correlation matrix cx of x will have its off-diagonal entries reduced by

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).
