levels() deletes other attributes
Dear All,
it seems to me that levels() deletes other attributes. See the following
example:
## example with levels
f1 <- factor(c('level c','level b','level a','level c'), ordered=TRUE)
attr(f1, 'testattribute') <- 'teststring'
attributes(f1)
levels(f1) <- c('L-A', 'L-B', 'L-C')
attributes(f1)

character strings with embedded commands: perl "/gee" ?
dear R experts---I am trying to replicate a perl feature. I want to be
able to embed R commands inside a character string, and have the
string be printed with the command executed. my perl equivalent is
my $a=10;
my $teststring = "the expression, $a+1, is ::$a+1::, but add one
more for ::$a+2::\n";
$teststring =~ s/::(.*?)::/$1/gee;
print $teststring;
of course, R does not use

Search and convert string function
Hi all,
I want to do this kind of function In R enviroment :
For example :
R <- 4
testString <- "I love $R"
then search this testString, when find "$R",replace "$R" to R ,and because
the value of R is 4
So the final string I want to get is "I love 4"
How can I implement? Thanks advance

Implementing a "plugin" paradigm with R methods
Dear list,
I was wondering how to best implement some sort of a "plugin" paradigm
using R methods and the dispatcher:
Say we have a function/method ('foo') that does something useful, but
that should be open for extension in ONE specific area by OTHERS using
my package. Of course they could go ahead and write a whole new 'foo'
method including the features they'd

RFC: "loop connections"
I've just implemented a generalization of R's text connections, to
also support reading/writing raw binary data. There is very little
new code to speak of. For input connections, I wrote code to populate
the old text connection buffer from a raw vector, and provided a new
raw_read() method. For output connections, I wrote a raw_write() to
append to a raw vector. On input, the mode

Updated rawConnection() patch
Here's an update of my rawConnection() implementation. In addition to
providing a raw version of textConnection(), this fixes two existing
issues with textConnection(): one is that the current textConnection()
implementation carries around unprotected SEXP pointers, the other is
a performance problem due to prolific copying of the output buffer as
output is accumulated line by line.

parse and pushBack (PR#2396)
Is this the last bug of the year? Well, it's the last one from me, anyway...
The "parse" function seems to give erratic behaviour when used in
conjunction with "pushBack" on an open connection (R1.6.1, Windows 2000).
Try this:
> { cat( c( '1', 'a+b', '2'), file='r123.r', sep='\n');
tcon_ file( 'r123.r'); open( tcon);

About Mcneil Hanley test for a portion of AUC!
Dear all
I am trying to compare the performances of several methods using the AUC0.1
and
not the whole AUC. (meaning I wanted to compare to AUC's whose x axis only
goes to
0.1 not 1)
I came to know about the Mcneil Hanley test from Bernardo Rangel Tura
and I referred to the original paper for the calculation of "r" which is an
argument of the function

How to compare areas under ROC curves calculated with ROCR package
Dear all,
I try to compare the performances of several parameters to diagnose
lameness in dogs.
I have several ROC curves from the same dataset.
I plotted the ROC curves and calculated AUC with the ROCR package.
I would like to compare the AUC.
I used the following program I found on R-help archives :

How to compare areas under ROC curves calculated with ROC R package
I might be missing something but I thought that AUC was a measure for
comparing ROC curves, so there is nothing else needed to "compare" them. The
larger AUC is the higher correlation of 2 variables compared. No other
measures or calculations are needed.

need help explain the routine input parameters for seROC and cROC found in the R archive
Please help.
I found the code in the archive.
The author of this script says: "The first function (seROC) calculate
the standard error of ROC curve, the second function (cROC) compare
ROC curves."
Can some one explain to me what are the na, nn and r parameters which
are used as the input to the following two functions?
Thanks much in advance.
