[R] reading in multiple data sets in 2 loops

Hello,
I have over 1000 csv data sets I need to read into R, so I want to read
them in using a loop. The data sets are named as
pheno_1000ind_4000m_add_h70_prog_1_2.csv,
pheno_1000ind_4000m_add_h70_prog_1_3.csv, ... so I need 2 loops (for the
last 2 numbers in the names). What I would like to do is the following:

setwd("C:/Research3/simulation1/second_gen")
d1<-read.csv("pheno_1000ind_4000m_add_h70_prog_1_2.csv")
d2<-read.csv("pheno_1000ind_4000m_add_h70_prog_1_3.csv")
d3<-read.csv("pheno_1000ind_4000m_add_h70_prog_2_3.csv")
.
.
.

I am wondering how I can accomplish this with a loop. Any suggestion is
appreciated!
I tried the following but it does not work:

data <- lapply(
 paste(("C:/Research3/simulation1/second_gen/pheno_1000ind_4000m_add_h70_prog_",[1:2],"_",[2:3],".csv",sep=''),
read.csv, header=TRUE, sep=',' )
names(data) <- paste("d", LETTERS[1:3], sep='')

Thanks!
