This is NOT critical. It arose due to a fumble fingers when developing an R example, but slightly intriguing.
How could one build a string from substrings with a single backslash (\) as separator. Here's the reproducible example: fname = "John"; lname = "Smith" paste(fname, lname) paste(fname, lname, sep=" / ") # BUT there's a glitch with backslash paste(fname, lname, sep=" \ ") # because of escaping character paste(fname, lname, sep=' \ ') paste(fname, lname, sep=' \\ ') # because of escaping character bslash <- "\\" print(bslash) paste(fname, lname, sep=bslash) Possibly the answer is that R never allows a single backslash in its strings, but I can imagine possible cases where I might want to output such lines, for example, in documenting this.
