I need to turn the character string: "1:5, 20:25, 50" into indices for
subsetting a vector.
For example: indices <- "1:5, 20:25, 50, 99" vector <- rnorm(100,0,1) # Please R, show me the way to achieve this: vector[indices] I thank you angels in advance for rushing in where this fool got bogged
down!
