Hello,
my_function seems to be a function you have defined somewhere in your code.
In your original post you mention it 3 times, this is the first one:
subnet_MYSUBNET <- my_function(MYSUBNET)
So Ivan's and Greg's code should work, they use a function you haven't
posted but is assumed to exist.
Note: if you are more comfortable with for loops than with *apply, I
would rewrite Ivan's for loop solution as
results <- vector("list", length = nrow(datatable))
for(val in datatable$column) {
results[[as.character(val)]] <- my_function(val)
}
To keep extending a vector or list object in a loop is inefficient, this
creates the list with the right length beforehand.
Hope this helps,
Rui Barradas

Greg,
here I get the error message:
Error my_function(val) :
cannot find function my_function.

Wolfgang,
result <- assign(paste("subnet_", val, sep = "")
result <- my_function(val)
i don't understand why you are twice assigning to =result=. also, the
first assignment doesn't seem well formatted (t's missing a value?).
did you mean something like
: assign(paste("subnet_", val, sep = ""), my_function(val))
(which i would think should work)?
cheers, Greg
