Hi All,
I am able to replace "r" with "x" for the word "Users" just for a test run.
*Code: newlist %>% mutate(.,new_col=str_replace(fpath,"r","x"))  *- this
works fine
But when I try to replace "\\" with "\".
*newlist %>% mutate(.,new_col=str_replace(fpath,"\\","\")) *, I get a
prompt ">" to complete the code. Not working. There is something on
backslashes to be "masked".
Any help would be appreciated.

                       fpath                         new_col
1 C:\\Users\\Anbu\\Desktop\\sas\\ C:\\Usexs\\Anbu\\Desktop\\sas\\
2 C:\\Users\\Anbu\\Desktop\\sas\\ C:\\Usexs\\Anbu\\Desktop\\sas\\
3 C:\\Users\\Anbu\\Desktop\\sas\\ C:\\Usexs\\Anbu\\Desktop\\sas\\
4 C:\\Users\\Anbu\\Desktop\\sas\\ C:\\Usexs\\Anbu\\Desktop\\sas\\
5 C:\\Users\\Anbu\\Desktop\\sas\\ C:\\Usexs\\Anbu\\Desktop\\sas\\

Thanks,
Anbu.

"\" is an escape in R. See ?Quotes for details.

Why do you want to replace '\\' with '\' in the file names?  They are
actually single '\' in the character string, but are printing out as '\\'.
see example below:

    > x <- 'a\\b'
    > x
    [1] "a\\b"
    > nchar(x)
    [1] 3

Thank you, Jim. That clarifies. I am trying to pass this path in a loop and
read the files  associated with the path.
Yes the length is 26 where double quotes are counted as single quotes. Let
me try to read the files using the collected path.

Really appreciate it.

Thanks,
Anbu
