If you are so productive that the rate-limiting step in your statistical programming is the number of times you need to type "<-", then your sample(c("MacArthur Award", "Nobel Prize", "Chambers Award"), 1, prob=c(0.1,0.1, 0.8) ) , will surely be granted in rnorm(1, 8) years. -- David. > > H > > -----Original Message----- > From: Erik Iverson [mailto:er...@ccbr.umn.edu] > Sent: Friday, June 18, 2010 1:23 PM > To: Greg Snow > Cc: Horace Tso; li li; r-help > Subject: Re: [R] questions on some operators in R > > > > Greg Snow wrote: >> Your example could also be used as an argument against allowing '=' >> as a shortcut for <- after all if you are used to using <- (rather >> than =) then you will see the problem with x<-2 right off.
