library(gsubfn)
as.numeric(strsplit(gsub("[c() ]","",gsubfn("([0-9]+)-([0-9]+)", ~as.numeric(seq(x,y)),x)),",")[[1]])

Subject: [R] convert delimited strings with ranges to numeric

Is there an easy way to convert character strings with comma-separated 
numbers and ranges to a numeric vector?

x<-  "2,5-7,10,12-15"

[1]  2  5  6  7 10 12 13 14 15

Thanks,
Chris
