A problem about "nlminb"

Hello everyone!

When I use "nlminb" to minimize a function with a variable of almost  
200,000
dimension, I got the following error.

nlminb(start=start0, msLE2, control = list(x.tol = .001))

Error in vector("double", length) : vector size specified is too large
I had the following setting

options(expressions=60000)
options(object.size=10^15)

That would do nothing on my machine, but then you may have a different  
(unspecified) OS. You may have unrealistic expectations. 10^15 seems a  
bit optimistic to me, even if you were supplying that number in a  
manner that R would recognize.

?mem.limits   #  should give you information specific to your OS.

If you use Windoze, try also:

I have no idea about what might be wrong. Any suggestion is highly
appreciated!!

And we have no idea what sort of setup you have. You could, of  
course,  read the specifics for your OS in the Installation Guide:
