Each dataframe is a gridded file, so I want to add the values at
corresponding grid cells from all the dataframes.

Sorry, I forgot to ask something.
When you say you want to add the df's values, what exactly do you mean?
All of the values, by row, by column, what?

Hello,

Note that you *never* need to set header = FALSE, it already is the
default of read.table. You would have to with read.csv.
old_dir <- setwd("~/directory")
f1990 <- list.files(pattern = "^199.*\\.txt$")
r1990 <- lapply(f1990, read.table)
setwd(old_dir)
Hope
