[R] Searching for keyword values in a text (configuration) file

[David Barron]

Something like this?

> library(Hmisc)
> t <- readLines("clipboard")
> t
[1] "DEVICE = 'PC'"             "CPU_SPEED = '1999', '233'"

> ix <- grep("CPU_SPEED",t)
> loc <- substring.location(t[ix],",")
> cpu <- substring(t[ix],loc$first+2)
> cpu
[1] "'233'"
