Thanks Dennis,
Your code also produces same as Jim's but I am not looking that one,
I need
to use "cbind" so that finally I will get the data frame of size
200X320
(i,e, 200 X(16X20)).
Thanks
Here we are a day later and your question risks sinking beneath the
waves because you have not realized that you are implicitly making
impossible demands on your volunteer consultants. Please review your
postings and responses and try to put yourself in the position of
someone who doesn't have the capacity to read your mind or see your
screen.

In addition to Jim's reply, had you used the plyr package, you could
have done this in one shot:
library(plyr)
DF <- ldply(llply(temp, read.table), rbind)
The inner llply call is equivalent to your lapply() and the outer
ldply() is equivalent to Jim's do.call() code.

Hi group,
I imported 16 data frames using the function "list.files"
temp <- list.files(path="...........")
myfiles = lapply(temp, read.table,sep = "")
Now I have 16 data set imported in R window.
I want to combine them by row and tried some thing like (Here I am
considering only 20 columns)
for(i in 1:16){
data<- cbind(myfiles[[i]][,1:20])
}
but it returns only first data set. I can combine them using
data <- cbind(myfiles[[1]][,1:20],myfiles[[2]]
[1:20],...............)
But I want in a loop so that I can make the efficient code.
Any kind of suggestion will be great for me.
Thanks
