"Open space-managed"??????????????????????? 1.4
"Mixed use"?????????????????????????????????????????? 5.2
"Residential-existing"??????????????????????????? 4.2
"Residential-existing"??????????????????????????? 7.1
"Residential-future"?????????????????????????????? 5.2
"Residential-existing"??????????????????????????? 1.2
"mixed use"??????????????????????????????????????????? 4.5
',sep="",header=TRUE)


library(reshape)

?Data1[,1]<-combine_factor(Data1[,1],c(2,2,3,4,5))


levels(Data1[,1])
#[1] "Mixed use"??????????? "Open space-managed"??
"Residential-existing"
#[4] "Residential-future"?
Data1[,1]
#[1] Residential-future?? Open space-managed?? Mixed use??????????

Sorry, this is what it should be:

DATA
TYPE ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?VALUE
Residential - future" ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?2.2
"Open space - managed" ? ? ? ? ? ? ? ? ? ? ? ?1.4
"Mixed use" ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 5.2
"Residential - existing" ? ? ? ? ? ? ? ? ? ? ? ? ? ?4.2
"Residential - existing" ? ? ? ? ? ? ? ? ? ? ? ? ? ?7.1
"Residential - future" ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? 5.2
"Residential - existing" ? ? ? ? ? ? ? ? ? ? ? ? ? ?1.2
"mixed use" ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?4.5


Which gives me these levelsLevels: Mixed use Open space - managed Residential -
existing Residential - future, mixed use


I need to combine mixed use and Mixed use into one category


Thank you very much. I really appreciate your help.
Thanks again
