v[is.na(v)]=0 -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rajarshi Guha Sent: Friday, November 21, 2003 2:38 PM To: R Subject: [R] using a logical vector as a mask?
Hi, say I have a vector: v <- c(1,2,3,NA,5,6,NA,7) And I would like to set the elements that are NA to, say, 0 I can use is.na() to get a logical vector: ind <- is.na(v) Is there a way in which I can use this logical vector to set the NA elements in v to 0?
