[R] R & bash script

[Christian Schulz]

Hi

how is it possible to use more than one command when i'm
didn't want use R CMD BATCH for specific reason?

$ echo "(x<-1:10)" | R --vanilla
works

$ echo "(x<-1:10 ;y<-20:30 ;lm(y ~ x))" | R --vanilla
works not.

Is it further possible using  bash variables like $i  from a loop
in the bash echo call  i.e.   dm$x$i$k <- 
read.data("dmdata$x$i$k.dat",header=T)

many thanks for a starting point!
