trouble with data frame
Le 22/03/13 12:34, Sahana Srinivasan a ?crit :
while (a<=10)
{
while (b<=10)
{
n<-as.numeric(df[a,b)];
...;
}
}
The problem is that when I print out 'n' I get the following errors :
"NULL" (if printed without as.numeric), and "numeric(0)" if printed with
the as.numeric.
Perhaps with n<-as.numeric(df[a,b]) )] are reversed Marc
