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.
Ghislain.
