Subtracting one based on an If
For the following:
Bldgid<-c(1000,1000,1000,1001,1002,1003,1003,1003)
Maplot<-c(20000,20001,20002,30000,30001,40000,40001,40002)
Area<-c(40,170,160,50,100,100,90,110)
#Construct Sample dataframe
MultiLotBldgs..<-data.frame(Bldgid,Maplot,Area)
CondoLots_ <- tapply(MultiLotBldgs..$Maplot, MultiLotBldgs..$Bldgid, length)
CondoLots_ Returns:
1000 1001 1002 1003
3 1 1 3
What i want to do is to subtract 1 from the above for all cases where there
are more than one, so that CondoLots_ returns:
1000 1001 1002 1003
2 1 1 2...
