Hello,
"double" and "numeric" are the same. From the help page for ?double,
section "Note on names"
"It is a historical anomaly that R has two names for its floating-point
vectors, double and numeric (and formerly had real)."
Apparently you are successfully converting characters to double
precision floating-point numbers.
Hope this helps,

Hi-
I have a 37 X 473971 character matrix that I am trying to convert into a
numeric matrix. When I use the code:
class(matrix) = "numeric"
I end up with something called a "double matrix" whose dimensions are
still 37 X 473971
I have also tried
new = apply(matrix,2, as.numeric) and got the same thing.
The analysis code I am ultimately attempting to run on this data
requires that it be in a numerical matrix, and it is really not okay
with a double matrix.
Does anyone know how to fix this?
Thanks.
