Why not just use an rbind() and create one data.frame?

Hi,
Is it possible use a loop to process many data frames in the same way?
For example, if I have three data frames, all with same variables
df_bs_id1 <- read.csv("test1.csv",header =TRUE)
df_bs_id2 <- read.csv("test2.csv",header =TRUE)
df_bs_id3 <- read.csv("test3.csv",header =TRUE)
How could I would implement a code loop that , for instance, would select
two coluns of interest in a fashion of the code below ?
# selecting only 2 columns of interest
for (1, 1:3) {
df_selected [i] <- df_bs_id[i] [ , c("column1", "column2")] }
Tks
