Assigning several lists to variables whose names are contained in other variables

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
