different plot symbols according to a factor

Dear R list subscriber,

I'm hoppiing my question didn't come up so far. I try to do somthing simple

  a<-c(1,4,5,2,7,34,56,78,76,54)
b=c(a<-c(1,4,5,2,7,34,56,78,76,54)
c<-c(0,0,0,0,0,1,1,1,1,1)

I would like to get a scatter diagram with different plot symbol for 0 and 
1 in c
I tried

plot(a,b, pch=c(1,2)[c])

which didn't work.

I appreciate if someone from the list could direct me in the right direction

Yours
Frank
