How to read in directory name as user input, without double backslashes?

Question

I want to write generic code which takes input from user, but when I run:

directory_name <- readline(prompt=" Enter the directory")

Enter the directory C:\\Users\\ANKIT\\Documents

It shows directory name like this (with double-backslashes)

directory_name "C:\\\\Users\\\\ANKIT\\\\Documents"

And how to use this directory name to load .csv file?

Answer 1

Use read.csv and paste0:

directory_name <- readline(prompt=" Enter the directory")

Enter C:\\Users\\griffinevo\\temporaryRfiles

read.csv(paste0(directory_name, "\\filename.csv"))

Answer 2

We can use paste0 to paste the file with the object directory_name

directory_name <- readline(prompt=" Enter the directory")
dat <- read.csv(paste0(directory_name, "\\mpg_data.csv"))

Or with paste and specify the sep

dat <- read.csv(paste(directory_name, "mpg_data.csv", sep="\\")) 
dim(dat)
