Dear list
Having read through all the archives of the mailing lists, I've had no
luck finding the answer to my problem.
I am running a for(i in 1:n) loop and am creating a matrix, p, for each
of the n observations. This matrix p is a 2x1 matrix. I am then doing
the following:
diagp<-diag(c(p[1,1],p[2,1]))
to create a matrix with the elements of P on the diagonal (i.e. a 4x4
matrix).
This works fine when I have n=60, however when I increase the size of
the data set to n=100, I get the error message:
Error in diag(c(p[1, 1], p[2, 1])) : subscript out of bounds
I put this down to a problem with memory at first so increased the
memory in my PC from 128Mb to 256Mb yet it made no difference and the
error still occurred. I am eventually going to need to run this command
for n=8000.
Could anybody suggest what I can do to solve this problem? Do I need to
store my matrix as another type of variable?
Thanks in advance for any help
Laura
