[R] How to create a numeric data.frame

[Aparna]

Hi All

I am new to R and  I am not sure of how this should be done. I have a matrix of 
985x100 values and the class is data.frame. 

A sample of my dataset looks like this (Since its a huge dataset and it would 
make the screen look more complex, I am pasting only the first few rows and 
columns.

When I try to use this command to convert it to numeric, 

as.numeric(leu_cluster1): I get an error Error: (list) object cannot be coerced 
to type 'double'. I tried several functions and looked into other forums too, 
but could not find a solution. i am trying to change it to numeric data.frame 
and not to a matrix.


thanks in advance. :)
