Convert comma separated string to integer in R

Question

I have a line in following format

IP1: IP2: 0.1,0.5,0.9

I split this line using following command:

myVector <- (strsplit(oneLine, \":\"))

Answer 1

Here'a an approach using scan:

oneLine <- "IP1: IP2: 0.1,0.5,0.9"
myVector <- strsplit(oneLine, ":")
listofPValues <- myVector[[1]][[3]]
listofPValues
# [1] " 0.1,0.5,0.9"
scan(text = listofPValues, sep = ",")
# Read 3 items
# [1] 0.1 0.5 0.9

And one using strsplit:

as.numeric(unlist(strsplit(listofPValues, ",")))
# [1] 0.1 0.5 0.9
