How to read multiple csv files and combine them into a single dataframe

Question

I'm using R. I have very many files in .csv format which I would like to read and then combine them into a data frame with each file representing a column, so that I can manipulate using simple statistics. How can I go about this?

Answer 1

Assuming that files contains the list of your files,

ff <- sapply(files, read.csv)
df <- Reduce(cbind, ff)

First command loads all files. Second command merges all files into one data frame. Clearly, I am assuming that all files have one column and the same number of rows. You can check that with

sapply(ff, nrow)
sapply(ff, ncol)

Answer 2

Data<-do.call(rbind,lapply(filelist,read.csv))
