[R] Coercing character string to function argument ?

[Derek Eder]

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!
