Hello,
I have a similar problem, but using the latest versions of R and raster:
"luse1"<-function(x){
x[x >=1 & x<=199]<-100 #Conservation land use
x[x >=200 & x<=299]<-200 #Native Vegetation extensive use
x[x >=210 & x<=210]<-210 #Grazing native vegetation
x[x >=221 & x<=222]<-220 #Production forestry
x[x >=300 & x<=399]<-300 #Dryland agriculture and plantations
x[x >=310 & x<=314]<-310 #Plantations
x[x >=321 & x<=325]<-320 #Grazing modified pastures
x[x >=331 & x<=338]<-330 #Cropping
x[x >=341 & x<=349]<-340 #Horticulture
x[x >=400 & x<=499]<-400 #Irrigated agriculture and plantations
x[x >=411 & x<=414]<-410 #Irrigated plantation
x[x >=421 & x<=224]<-420 #Irrigated pasture
x[x >=431 & x<=439]<-430 #Irrigated cropping
x[x >=441 & x<=449]<-440 #Irrigated horticulture
x[x >=451 & x<=455]<-450 #Irrigated seasonal horticulture
x[x >=500 & x<=599]<-500 #Intensive uses
x[x >=600 & x<=699]<-600 #Water
x[x >=611 & x<=614]<-610 #Lake
x[x >=621 & x<=623]<-620 #Reservoir or dam
x[x >=631 & x<=633]<-630 #River

return(x[])
}
