Try this also:
sapply(grep("string$", vec), function(idx)paste(vec[idx + 0:1], collapse = ""))

A different approach than those other people listed would be to change
the vector into a matrix (by setting its dimension, if you don't need
to keep the original vector) and then applying paste along one of the
dimensions. Obviously, you'd need to pad the end of the vector with
NAs or empty string
thanks so much, this did the trick!

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 sin
