I want to use read.table to input many files, each for a different

this? Thank
you!
for (t in 1970:2005)
{ edge <- read.table(file="edge_t.csv", header=T, sep=",")
## I will have many rows of code following the read.table line

Two things:
1. Not extremely important here at all, but for the future: just note
that but by using "t" you're trampling over the transpose function
t(), so perhaps you can use a more descriptive variable to both make
code more readable and less ... urm, trample-itve :-)
2. Answer:
for (year in 1970:2005) {
edge <- read.table(file=sprintf("edge_%d.csv", year), header=T,
sep=",")
...
}
You can also use the paste function in place of sprintf
