aov(HSuccess ~ different VegIndexes)

Hi R-listers, 

I would like to do an ANOVA with HSuccess ~ each individual Vegetation index
(0-5m, 6-10m, 11-15m, 16-20m, 21-25m, 26-30m, 31-35m) and alternatively
HSuccess ~ HTLIndex (-5-(-1m), 0-5m, 6-10m, 11-15m, 16-20m, 21-25m, 26-30m). 

I'm not sure how to write the script for it. I have tried:

summary(aov(HSuccess ~ ((data.to.analyze$Veg
breaks=c(0,5,10,15,20,25,30,35)), data=data.to.analyze)

Error: unexpected symbol in "summary(aov(HSuccess ~ ((data.to.analyze$Veg
breaks"

AND

summary(aov(HSuccess ~ VegIndex$0-5, VegIndex$6-10 + VegIndex$11-15 +

VegIndex$16-20 + VegIndex$21-25 + VegIndex$26-30 + VegIndex$31-35,
data=data.to.analyze)
Error: unexpected numeric constant in "summary(aov(HSuccess ~ VegIndex$0"

Any suggestions on how to do this? 

Jean
