I'd recommend:
a) using cppFunction instead of the older cxxfunction
b) creating an example that anyone can copy and paste out of their
email client and into R.
You are more likely to get helpful responses if you reduce the burden
on the potential helpers as much as possible

Thank you for your quick reply!
I corrected the issue mentioned by you, but I get the same error.
It must be a beginner's issue.
The data is quite big, but this kind of output could be produced with any
random data, I guess.
Namely, using the Rcpp, I get Am as:
[,1] [,2] [,3] [,4] [,5] [,6

Not for me, because my vanilla copy of R doesn't know about dataqtr. It's
helpful to provide reproducible examples.

Hello,
The following code works well in R:
attach(dataqtr)
dataqtr <- data.table(dataqtr)
setkeyv(dataqtr,c("gvkey","qtr"))
vec_growth <- data.frame(0,0,0,0,0,0,0,0,0,0,0,0,0)
vec_eps<- data.frame(0,0,0,0,0,0,0,0,0,0,0,0,0)
T <- 15
for (i in 1:nrow(dataqtr)) {
vec_growth[i,] <- ( dataqtr[
