[R] Turning a logical vector into its indices without losing its length

I have the code below which gives me what I want for temp based on logvec but I was wondering if there was a shorter way ( i.e : a one liner ) without having to initialize temp to zeros. This is purely for learning purposes. Thanks. logvec - c(TRUE,FALSE,FALSE,TRUE,FALSE,FALSE,TRUE,FALSE)

Hi Erin, Since the error occurs during the loading of the gtools package, I would suggest upgrading to a newer version of gtools to see if this solves your problem. -G On Aug 24, 2007, at 12:49PM , Erin Berryman wrote: Dear R community, I am using R version 2.4.1 GUI 1.18 on an iBook G4
