Try this which assumes that comma does not appear in any of the strings.
You can substitute a different non-appearing character if a comma does
appear in any of the strings:
strsplit(gsub("string,", "string", paste(vec, collapse = ",")), ",")[[1]]
It first runs all the strings together into a single comma-separate string
using paste and then replaces each occurrence of "string," with "string"
using gsub. Finally it breaks the long string back up into individual
strings using strsplit.
