Thanks a lot Boris, I tried out your worked out solution and it works just
perfectly fine. No doubt I need a lot of practice with regexr and the pattern
stated by you - I will do that now. Thanks a lot for pointing me in the right
direction. Appreciate it a lot.
Sam.

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.
