Is there a way to do this in a loop? Thank you.

f <- function (filename) {

for (filename in paste0("data", 1:24, ".csv")) f(filename)
Depending on what exactly you have in your file system,
for (filename in system("ls data*.csv", TRUE)) f(filename)
might work.

Steven,
It depends what you want to do. What you are showing seems to replace the
values stored in "data" each time.
Many kinds of loops will do that, with one simple way being to store all the
filenames in a list and loop on the contents of the list as arguments to
read.csv.
Since you show

The pin,
Try
for (ind in 1:24)
{
data = read.csv(paste0("data", ind, ".csv"))
...

Hi Dirk. If you use use-package, you can pin the package source for ess
to gnu-elpa like this:
(use-package ess
:ensure t
:pin gnu)
Documentation for use-package can be found here:
https://www.gnu.org/software/emacs/manual/html_node/use-package/index.html
Section 5.2 discusses :pin.
Rodney et al,
Thanks for the update(s)!

This is hard if not impossible to implement for the general case
because the default arguments are
Hi Reed,
I need to stress before giving my answer that no solution can handle
everything. These scenarios will always lead to problems:
* if any of the formal arguments rely on the current state of the call stack
* if any of the formal arguments rely on a variable that is only
defined later in
I'm wrapping a function in R and I want to record all the arguments
passed to it, including default values and missing values. I want to
be able to snoop on function calls in sourced scripts as part of a
unit testing framework.
I can capture the values fine, but I'm having trouble evaluating them
