Extracting csv file names without extension R

Question

I have a folder with different files. What I'm trying to do is to extract file names without extensions of csv files only.

for example: if i have a folder with files

cp1.csv 
cp2.csv 
sd.exe 

I'd like to get a vector:

"cp1" "cp2" 

Answer 1

You could use a list.files() gsub() combo

basenames<-gsub("\\.csv$","", list.files(pattern="\\.csv$"))

Answer 2

An alternative to gsub would be file_path_sans_extension from "tools". Try:

library(tools)
file_path_sans_ext(list.files(pattern = "*.csv"))

Not much added here, but it's still a fun function to know about :-)
