R help - Jun 2012 - cannot use simple=TRUE in boot

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!

Hello,

Your code works with me, unchanged:


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

ORDINARY NONPARAMETRIC BOOTSTRAP


Call:
boot(data = c, statistic = table, R = 100, sim = "ordinary",
     stype = "i", simple = TRUE)


Bootstrap Statistics :
     original  bias    std. error
t1*    500.5 0.76209    8.876232


But your error message shows a typo in 'simlpe' so, check your typing.

Also, 'c', 'table' and 'boot' are really bad names for
data objects or
functions, they already are R functions.

Hope this helps,

Rui Barradas
