Hi, I'd like to store N vectors of different lengths, and to be able to access them with an index, and eventually free the memory for one of them without modifying the indexes to the others.
int *pv[3];
pv[0] = (int *) malloc(13 * sizeof(int)); pv[1] = (int *) malloc(7 * sizeof(int)); pv[2] = (int *) malloc(110 * sizeof(int));
free(pv[1]) ...
What is the best data type (or class) in R to do such a thing?
A list, with vector elements (index starts at 1 in R):
pv = list() pv[[1]] = real(13) pv[[2]] = real(7) pv[[3]] = real(110)
then the equivalent of freeing the memory and keeping the indexing would be:
pv[[2]] = real(0)
and NOT
pv[[2]] = NULL (which deletes element 2)
*BUT* I dont know if R will really free() the memory at that point. You may need to force the garbage collection with gc()....
