Naming elements of a list as a function of x in r

Question

Here I am trying to name the individual elements of this list as a function of x so that I may index it later like one would with a dataframe or vector, yet I keep getting the error message

Error: unexpected '=' in "Indxlist <- sapply(1:1600, function(x) list( (x) ="

Here is the code that I am attempting to use...

Indxlist <- sapply(1:1600, function(x) list( (x) = dataframe1[,x]))

Thanks!

Using an example data, your code works. Do you 1600 columns in your dataset? — akrun, Jul 13 '16 at 16:33
my bad, the code had parentheses around the x. I am trying to name the elements $1 through $1600 so they don't change when I index specific ones. — Zach Eisner, Jul 13 '16 at 16:40
the problem with that is that the element names with "x" are all "$x" — Zach Eisner, Jul 13 '16 at 16:46
Is there a way to get the column names to be $1 through $1600 instead of [[1]] through [[1600]] — Zach Eisner, Jul 13 '16 at 16:48

I think this cannot work. You cannot name a list with integers. Just do this after your command (which is not good practice anyways):

names(Indxlist) <- 1:1600

That worked! And thanks for the good practice note. As can be seen, I'm very new and inexperienced with coding. Thank you for the help though! – Zach Eisner Jul 13 '16 at 17:01
Glad, if that helped. If you want to accept this answer, I'd appreciate it. :) – Jul 14 '16 at 08:38
