Your immediate problem is that 'y' is
not reset to 1.
Easier code to write would be to use
'for' loops rather than 'while' loops.
Better still would be to use neither if
possible. I suspect that you are in
Circle 3 of 'The R Inferno'.

Hi everyone,
I'm using the following code to go over every element of a data frame (row
wise). The problem I am facing is that the outer 'x' variable is not
incrementing itself, thus, only one row of values is obtained, and the
program does not proceed to the next row.
This is the code:
while(x<=coln)
{
while(y<=rown)
{
n<-as.numeric(df[[y]][x]);
if(n>0)
{
lim<-(n-1);
S<-100;
(...)
}
opdf[[y]][x]<-sum;
}
y<-y+1;
}
x<-x+1;
}
Here is a sample of the input data:
GENE A CD EF GH IK LM NP QR ST VW Y 2amt:Amet_0001 29 023 3417 1612 4229 39635
