A flexible way for doing this is to define logical vectors for the types of samples that you want to include or exclude. You can then use logical negation to select the complementary set:
inSet1 <- HData$H < 1.3 inSet2 <- HData$H < 8 & Hdata$DBH > 20 HDataPart1 <- Hdata[!inSet1, ] HDataPart2 <- Hdata[!inSet2, ] -Christos -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ghislain Vieilledent Sent: Thursday, April 20, 2006 8:55 AM To: r-help@stat.math.ethz.ch Subject: [R] The contrary of command %in% Dear r-list, I've got a data base: > HData[1:10,] NumTree Site Species Date Age DBH H IdentTree 1 1 Queige Spruce 2002 184 49 33.5 Queige 1 2 2 Queige Fir 2002 NA 5 4.6 Queige 2 3 3 Queige Fir 2002 25 8 6.6 Queige 3 4 4 Queige Spruce 2002 198 47 32.5 Queige 4 5 5 Queige Fir 2002 200 59 35.3 Queige 5 6 6 Queige Spruce 2002 80 16 9.4 Queige 6 7 7 Queige Fir 2002 NA 5 4.2 Queige 7 8 8 Queige Fir 2002 200 44 32.5 Queige 8 9 9 Queige Fir 2002 NA 5 3.4 Queige 9 10 10 Queige Spruce 2002 167 48 32.8 Queige 10 ... I want to remove particular points determined by > HDataPartP<-HData[H<1.30,] and > HDataPartP2<-HData[H<8&DBH>20,] That's why I want to use subset in a close form to: HData2<-subset(HData,HData$H>1.30&HData$IdentTree "not"%in%HDataPartP2$IdentTree) How should I do that ? Is there any R-syntax saying "not element of that object" ? Thanks for your help.
