Hi the list, I include some C code in a R function using .C. The argument is a character. I find how to acces to the characters one by one:
--- 8< --- C ------------ void dealWithCharacter(char **chaine, int *size){ int i=0; for(i=0;i<*size;i++){ Rprintf("Le caractere %i est %c\n",i,chaine[0][i]); }; } --- 8< ------ R --------- ch <- "zerta" .C("dealWithCharacter",as.character(ch),as.integer(nchar(ch))) --- 8< ------------------ But is it possible to acces to the full word at once?
