[R] Help with 'memory not mapped'

I'm no expert programmer at all;
I'm running an R script ("mariam1_2.R"). This scripts calls another script, which contains an R function, which .Call some C code. It runs several times without any problem, but sometimes I get the error:


  1. .Call("rrfunc", as.double(dx), as.integer(nrows), as.integer(ncols), as.double(deltadt), as.character(binmaps), as.integer(ldd), as.double(downst),as.integer(outl), as.double(maxinte), as.double(nmn))
  2. rrfuncR(dx, nrows, ncols, delta.t,binmaps.pathed,ldd,downst, out.index,interc,n.man)
  3. eval.with.vis(expr, envir, enclos)
  4. eval.with.vis(ei, envir)
  5. source("rrprogv1_2.R")
  6. eval.with.vis(expr, envir, enclos)
  7. eval.with.vis(ei, envir)
  8. source("mariam1_2.R")

Possible actions:

1: abort (with core dump, if enabled)
2: normal R exit
3: exit R without saving workspace
4: exit R saving workspace


I've seen something related in the documentation, but it is not easy to understand it for me. I'm trying to perform a Monte Carlo analysis that calls the function iteratively. My question is why sometimes I can call forty or fifty times the function without any problem, and other times it crashes at the first, second or 6th time. Can you give me any advice?

Thanks and best regards,
