[REBOL] Picks

From: andrew::martin::colenso::school::nz at: 12-Aug-2003 17:49

For those times, when there just isn't enough pick... :) Here's my nifty function of the day: Picks: func [ {Returns the values at the specified positions in the series.} Series [series! pair! event! money! date! time! object! port! tuple! any-function!] Indexes [block!] ] [ foreach Index Indexes collect/only [ pick Series Index ] ] And I use it like this: transpose Picks transpose Table [1 2 5 6 8 9 11 12 14 15 17 18] to pick out columns from a table by index number.
