How to escape backslashes in R string

Viewed 54378

I'm writing strings which contain backslashes (\) to a file:

x1 = "\\str"

x2 = "\\\str"
# Error: '\s' is an unrecognized escape in character string starting "\\\s"

x2="\\\\str"
write(file = 'test', c(x1, x2))

When I open the file named test, I see this:

\str
\\str

If I want to get a string containing 5 backslashes, should I write 10 backslashes, like this?

x = "\\\\\\\\\\str"
