[R] Putting directory path as a parameter

[aajit75]

Hi List,

I am new to R, this may be simple. 

I want to store directory path as parameter which in turn to be used while
reading and writing data from csv files.

How I can use dir defined  in the below mentioned example while reading the
csv file.

Example:
dir <- "C:/Users/Desktop" #location of file

temp_data <- read.csv("dir/bs_dev_segment_file.csv")

If I run this it will show errors:

Error in file(file, "rt") : cannot open the connection
In addition: Warning message:
In file(file, "rt") :
  cannot open file 'dir/bs_dev_segment_file.csv': No such file or directory

Regards,
-Ajit
