[R] another little problem embedding R

[Didier Leibovici]

I was using 
num <-scan("",numeric(0))
in a file to be ran in batch or with R --vanilla <bidon.R

but I don't know how to make it wait for the value ???
i.e. if you do the same typing

19 didier at mace $ R --vanilla

R : Copyright 2001, The R D

> source("bidon.R")
1: 1
2: 33
3: 999
4: 
Read 3 items
> num
[1]   1  33 999
> q()

the "batch" gave
20 didier at mace $ R --vanilla <bidon.R

R : Copyright 2001, The R Development Core Team
Version 1.2.3  (2001-04
> num <- scan("",numeric(0))
1: Read 0 items
> q()

and if you put source("bidon.R) in Runbidon.R
22 didier at mace $ R --vanilla <Runbidon.R
...
> source("bidon.R")
1: Read 0 items
> 
23 didier at mace $ 


Is there any options or variables to change to make it ...wait!
thanks
