[R] the first name of the first column

[greg holly]

Dear all;

I need to run heatmap. Because my first column in my data is alphanumeric,
I can not run as.matrix(scale(my_data)). So I need to make my data readable
as in data(mtcars). In *mtcars *data the first column is alphanumeric and
has no  name.

Thanks,

Greg
