R: How do I replace \\ with /?

Question

In R I have a string like

file = "c:\\hello\\nihao"

How do I replace all the \ with /? The ?gsub documentation is really confusing! You should get extra points for pointing to a good R regex resource!!

Answer 1

Why not just use the fixed = TRUE argument?

gsub("\\", "/", file, fixed=TRUE)
# [1] "c:/hello/nihao"

Alternatively:

gsub("\\\\", "/", file)
# [1] "c:/hello/nihao"
