I've done more searching and found a problem with the data in one of the
matrices that was corrupting the calculation. Data now fixed and problem
is solved. Apologies if anyone wasted time on this.

Dear Jamil,
Presumably, the variables alloc.dose, r0, r1, and r2 will exist in the global
environment when you call the compiled function lf1.c(), but didn’t exist when
you compiled the function. If so, then lf1.c() should work properly despite the

Dear R-users,
I would like to seek your suggestion. I have the following code which runs
smoothly. But when I compile the function (lf1.c), it shows "no visible
binding for global variable" for some of the arguments.

nothing to do with multiplication, but without the code there is no way to say
for sure.

Hi all. A question about performance of matrix multiplication.
I have two relatively large matrices:
A is 100x3072, all integers 0-255, not sparse
B is 1016x3072, all integers 0-255, not sparse
The command z<-B %*% t(A) works fine and takes roughly 0.2 seconds . If I
add one row to B, t
