[R] Help with a third ggplot error

[Boris Steipe]

(Technically you are now thread-hijacking. But here goes:)


mydf <- data.frame(V11 = c("DD Pack0.002",
                           "FTA English News0.003",
                           "FTA Complimentary0.004"),
                   stringsAsFactors = FALSE)

# regex matching start-of-string(letters or blanks)(numbers, a decimal
# point, more numbers)end-of-string: "^([a-zA-Z ]+)([0-9]+\\.[0-9]+)$"

# first check that all elements are matched by the regex. If not, an assumption
# of how the strings are patterned is not true ... 
all(grepl("^([a-zA-Z ]+)([0-9]+\\.[0-9]+)$", V11))  # must be true!

mydf$`Channel name` <- gsub("^([a-zA-Z ]+)([0-9]+\\.[0-9]+)$", "\\1", mydf$V11)
mydf$Price          <- gsub("^([a-zA-Z ]+)([0-9]+\\.[0-9]+)$", "\\2", mydf$V11)

mydf
#                      V11      Channel name Price
# 1           DD Pack0.002           DD Pack 0.002
# 2  FTA English News0.003  FTA English News 0.003
# 3 FTA Complimentary0.004 FTA Complimentary 0.004


Note this _will_ give wrong results if channel names like "ABC4" exist.
