The string vector actually comes as a part of a list, and the vector is
named "int", and the numbers are strings. I then have to make it a vector
that is still called "int" and has 4,5,6 etc. the types are either integer
or numeric. The number of items in the vector is unknown.
here's an example,
a list has vectors
INT
"2"
"3"
"4"
NUM
"2.37"
"4.56"
