[R] Can ucminf be installed in 64 bit R and one more question?

[Ravi Varadhan]

I don’t understand your question about the hessian.  Did you try hessian()
function in "numDeriv" on the result from optim directly rather than using
"ucminf"?  Also, what do you mean by `failed'?  What error message did you
get?

Subject: [R] Can ucminf be installed in 64 bit R and one more question?

Hey, R Users

my windows is 64 bit windows 7. I am trying to install the package ucminf
into 
my 64 bit version R but cannot.  the package I downloaded is from 
http://cran.r-project.org/web/packages/ucminf/index.html and I installed it
with 
the "install from local zip files", due to I did not connect my computer to 
internet. 


did anyone meet this problem and is there a version of ucminf for 64 bit R?

the question is: why the ucminf (for 32 bit R) with option hessian=3 always
give 
hessian matrix while most of other methods failed (includiing the option 
hessian=1 which using numDeriv)?

thanks for any information
