Debug help

Hi, 

I am getting the following error: argument is of length zero

My code:
temp <- 0
for (j in 1 : 3) {
for (k in 1 : 12) {
temp <- temp + as.double(C[k, (q - 1) * 3 + j]) * as.double(m_ret_reb[i + k
- 1, j+1])
}
}

Why would R handle my temp variable as numeric(0)?

You need to send a reproducible example if you want an answer.  It's 
more likely a problem with C or m_ret_reb or q, and we don't have those.

Thanks Duncan,

I am translating code from Matlab into R and am still finding my feet in
R.
I first run TriskellData and the compute_strategy. In Matlab this is a
function, so I would be looking to do the same in R. 
The bug is in compute_strategy. I would appreciate any help you can
give.

Thanks,
Eduard
