[R] cannot use simple=TRUE in boot

[he chen]

I am doing boot with a large database, thus want to use simple=TRUE to
reduce the memory used.
I alreday set up sim="ordinary", stype="i" , but I don't know how to
set "n=0". In fact, I don't know what does "n=0" mean?
For example,

a<-c(1:1000)
b<-c(2:1001)
c<-cbind(a,b)

library(boot)
table<-function(c,indices){
  d<-c[indices,]
  e<-mean(d[,1])
  return(e)
}

boot<-boot(c,table,100, sim="ordinary", stype="i",simple=TRUE)


AND, r give "Error in statistic(data, original, ...) : unused
argument(s) (simlpe = TRUE)"

Thanks a lot!
