R use variable within regex

Question

Okay - maybe this is a better example. I am looking for guidance/references on how to reference a variable within a regex - not how to build a regex for this data.

Answer 1

Try this:

> d1 <- c("CCA: 135 cm/sec ICA: 50 cm/sec", "CCA: 150 cm/sec ICA: 75 cm/sec")
> t(strapplyc(d1, "\\w+: \\S+ \\S+", simplify = TRUE))
     [,1]              [,2]            
[1,] "CCA: 135 cm/sec" "ICA: 50 cm/sec"
[2,] "CCA: 150 cm/sec" "ICA: 75 cm/sec"
