Hello,
The backslash is not a character of the string str. test it with nchar:
str = '<span id=\"ctl00'
nchar(str)
#[1] 15
It is there just to escape the double quotes.
if you want a backslash you would need to escape it, like in str1.
str1 = '<span id=\\"ctl00'
nchar(str1)
#[1] 16
Now yes, you can remove it.
str2 <- gsub("\\", "", str1, fixed = TRUE)
identical(str, str2)
#[1] TRUE
Hope this helps,
Rui Barradas

Hi,
I have below string where I am trying to remove Backslash from. I tried
with gsub() function, however failed to remove that:
str = '<span id=\"ctl00'
gsub("\\", "", str)
Error in gsub("\\", "", str) :
invalid regular expression '\', reason 'Trailing backslash'
Any pointer to the right approach?
Thanks for your time
