[R] boot with different sample sizes

[paolo brunori]

Dear all,
a question about the package boot: is it possible to bootstrap a 
function of arguments of different length? is there an alternative package?
below an example of a simple try,

many thanks
paolo

> library(boot)
> blue<-c(4, 3, 4, 1, 2, 3, 1)
> red<-c(4, 3, 4, 1, 2, 3, 1, 2, 3, 1, 3, 2)
>
> test1<-function(x,y,d){
+ 	return(sum(x) - sum(y))
+ 	}
> b=boot(red blue, test1 ,R=10)
Error: unexpected symbol in "b=boot(red blue"
