Can anyone provide an elegant solution?

Thank you. This was a mistake from me, I actually did not load the
package.
Sorry for this!

PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
Dear R-help:
Is there a way to extract a robust covariance matrix from optim? I am looking
for one of the form H V H; where H is the inverse of the Hessian, and V is
dLL/dT * dLL/dT (LL=Log-likelihood, T=vector of parameters, d is the partial).
Optim returns H, which approximates for the c
Are there any functions that include this process?

Scot,
Thanks for the additional information. On further
reflection... whether one uses SAS PROC EXPORT or uses
a SAS LIBNAME yourfile XPORT 'yourpathname';
statement, an intermediate file is created in either
case. As far as experience tells me now, PROC EXPORT
is a far superior choice, because
Scot,
Thanks for the info. I will try your code out to
verify the result, but before I do that, will your
code (SAS and R) work with variable names that are
longer than 8 characters long without truncating the
variable name in R?
Also, I wonder about using your method or the PROC
EXPORT method w
I'd like to thank the R Core Team for making the
parameters clearer for me on how to solve this
problem.
I think for now I will try to do most data management
tasks in SAS (from Oracle) and then use PROC EXPORT in
SAS to create a csv file that R can read and then I
can do my graphics, for publicat
Thomas,
The SAS data set I PROC CPORTed is [9] the result is
[10]. I PROC CIMPORTed [10] back to its orginal
state [9], and it worked.
So the SAS people think that the error is not with the
SAS XPORT file, but with R trying to load a text SAS
XPORT file, when it should be loading the SAS XPORT

read.xport("J:\\QM\\Reports\\Sarthur\\SAS_Application\\SAS_Data_Sets\\use")
Error in lookup.xport(file) : unable to open file

I did do that originally, I just mis-tpyed it, and it
did not work.
I talked with people at SAS, and they said the PROC
COPY SAS code was good, but that I just need to play
around with the R parameters for read.ssd
Will get back to you on this issue.
If you have any a
anyone help me get to the next step of this
process? I believe I am close to getting R to read
SAS permanent data sets directly, which I would really
like to be able to do.
Thanks,

I just downloaded and installed R 1.6.1 on my Windows
machine where I also run SAS.
I want to use the 'read.ssd' function so that I can
convert a permanent SAS data set into an R data frame.
I downloaded and installed the package 'foreign' on my
machine, which includes the 'read.ssd' function.
