r - convert a string range of values to numeric range -


i have following type of values in 1 column of data.

£48.00 - £52.00

first have remove £ sign, done with

v <- gsub('£'," ",£48.00 - £52.00)

v string.

> v [1] " 48.00 -  52.00"

how can transform v numeric v 48.00 - 52.00?

we use str_extract extract numeric part along .. output list. can loop through list sapply , median after converting 'numeric'.

library(stringr) sapply(str_extract_all(str1, '[0-9.]+'), function(x) median(as.numeric(x)))

data

str1 <- "£48.00 - £52.00"
