[R] Converting chr to num

[Rui Barradas]

Hello,

You have to get rid of the percent sign first. This can be done with ?sub

x <- "12.6%"
y <- sub("%$", "", x)
z <- as.numeric(y)

1) The dollar sign means "end of string". See ?regexpr.
2) You can all of that in one code line, no need to create y.

z <- as.numeric(sub("%$", "", x))


Hope this helps,

Rui Barradas
