I am trying to check for backslashes in data, then remove them when I

do it. I know the backslash is the escape character in R, and I
should be able to use 'gsub' to accomplish this, but I all I seem to
be getting are errors. For example:
If entry is:
"Hello\World"
I want:
"HelloWorld"
There are several entries with backslashes, and I need to find them
and delete them. All help is welcome, thank you.
This gets a little confusing because print() automatically doubles
backslashes. To see what's really going on, you need to use cat. Then
the following can be seen to work:
input <- "\"Hello\\World\""
cat(input, "\n")
output <- gsub("\\\\", "", input)
cat(output, "\n")
