[R] "as.numeric"

[Jessica Lam]

Dear R user,

After I imported data (csv format) in R, I called it out. But it is in
non-numeric format. 
Then using "as.numeric" function. 
However, the output is really awful !!!!! 

> PE[1,90:99]
           V90          V91          V92          V93          V94         
V95          V96          V97          V98          V99
1  16.8467742   17.5853166   19.7400328   21.7277241   21.5015489  
19.1922102   20.3351524   18.1615471   18.5479946   16.8983887 

> as.numeric(PE[1,90:99])
 [1] 11 10 11 10 11  9 10  9  9  8

 How can I solve the above problem??

Thanks so much!
Jessica
