It is hard to understand that your R code will not work with a
double matrix since double is just short for double precision
floating point matrix. Your only alternative would be integer.
"It is a historical anomaly that R has two names for its
floating-point vectors, double and numeric (and formerly had
"double is the name of the type. numeric is the name of the
mode and also of the implicit class."

Subject: [R] double matrix?
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
that it be in a numerical matrix, and it is really not okay
with a double
Does anyone know how to fix this?
