Dear all,
I am trying to split a matrix into 2 as efficiently as possible.
It is a character matrix:
1 2 3
1 "2-271" "2-367" "1-79"
2 "2-282" "2-378" "1-90"
3 "2-281" "2-377" "1-89"
I want to make 2 matrices from this, as succinctly and efficiently as
possible.
I've tried
used the
table later in loops. Is there an easy way to re-index the table?
Kind regards
Jim

same thing much more efficiently.
bascially I have a dataframe with charac
