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 filenames as having a number from 1 to 24 in middle, you can
make such a vector using paste().
A somewhat related question is if you want to concatenate all the data into one
larger data.frame.

Subject: [R] Looping
I need to read csv files repeatedly, named data1.csv, data2.csv,… data24.csv,
24 altogether. That is,
data<-read.csv(“data1.csv”)
…
data<-read.csv(“data24.csv”)
…
Is there a way to do this in a loop? Thank you.
