Dear all,
I am really new to R, and I have problem here. I searched around, but did
not get a solution.
I have a numetrix matrix (20 by 25) saved in .csv. I read it as
>sx<-read.csv("sx.csv",header=F)
Then I try to convert it to numeric using
>sx<-as.numeric(sx)
Error: (list) object cannot be coerced to type 'double'
The class of sx is "data.frame".
I tried to unlist it as,
s<-unlist(sx), but when I look at the dimension,
> dim(s)
NULL
Can anyone tell me how should I load my data as a numeric matrix rather than
"data.frame", or how to convert the data.frame matrix into numeric?
Thank you very much.
Wendy
