R help - Apr 2015 - clusterR (fun=aggregate) error "number of items to replace is not a multiple of replacement length"

I am getting the above  error with clusterR and aggregate:

works fine without parralell:

library(raster)
r<-raster(matrix(data = sample(c(1:10,NA),10000,replace=T),100,100),xmn=0,
xmx=1000,ymn=0,ymx=1000)
beginCluster()
Parr_agg<-clusterR(r,fun=aggregate,args=list(fact=3,fun=modal,expand=TRUE,na.rm=TRUE))
endCluster()
agg<-aggregate(r,3,fun=modal,na.rm=TRUE)
plot(agg)

Apoligies.  did not read help properly it states:
"Among other functions, it does _not_ work with ... (dis)aggregate"
