I am trying to store the special escape character `\` in R as part of a string.

```
x = "abcd\efg"

# Error: '\e' is an unrecognized escape in character string starting ""abcd\e"

x = "abcd\\efg"

# Works

```

The problem is that `x` is actually a password that I am passing as part of an API web call so I need to find a way for the string to store a literal single slash in order for this to work.

Example using the ignoring literal command:

```
> x = r"(abcd\efg)"

> y = "https://url?password="

> paste(x, y, sep = "")
[1] "abcd\\efg123"

> # What I need is for it to return
[1] "abcd\efg123"

> z = paste(y, x, sep = "")

> z
[1] "https://url?password=abcd\\efg"

> cat(z)
https://url?password=abcd\efg

```

When I pass `z` as part of the API command I get "bad credentials" message because it's sending `\\` as part of the string. `cat` returns it to the console correctly, but it appears to not be sending it the same way it's printing it back.
