r - RStudio fatal error while generating matrix -

-

i'm processing 2 char vectors outer function, results in matrix. i'm using levensthein function, compares 2 strings , outputs simialirity of them, each item vectors.

for tests 1000x1000 vectors, runs fine. runs in 4.95 sec.

 calc_levensthein_d <- function(vector1,vector2){     #total matrix    total <- as.matrix(outer(vector1,vector2,levenshteinsim))     return(total)  }

however 10000x5000 vector, fatal error message, @ ending of processament.

here tests:

~1000x1000 -> 4~6 sec

~1000x5000 -> 40~60 sec

~10000x1000 -> 688 sec ~ 11min

~10000x5000 -> fatal error after 2hours

it's memory problem? ideias? goal process 120000x10000 matrix.

obs: levenshteinsim record linkage package.
