Hi everyone,
I am trying to use the values from every cell of the data frame in a
further calculation.
This is the code that I am using to catch every element of the data-frame.
while (a=10)
{
while (b=10)
{
n-as.numeric(df[a,b)];
...;
}
}
The problem is that when I print out 'n' I get the
Sahana,
The notation
df[a,b)]
is plain wrong. I think you meant (but I may be mistaken)
df[a, b]
and I am not still sure if that would work in your example. Have you
instead considered subset()? E.g.,
subset(df, a = 10 b = 10)
See ?subset for more details.
Also, df is a very bad name

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.
