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

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!
