[R] Creating vegetation distance groups from one column

Thank you! That has worked for me when creating graphs. In plyr I used the

# Veg Index 
data.to.analyze$VegIndex <- cut(data.to.analyze$Veg,
      breaks=seq(0, 35, 5), include.lowest=TRUE)
VegIndex <- data.to.analyze$VegIndex

But the vegetation distances on the x-axis in the graph are showing up as: 
[-5,0] (0,5] (5,10] (10,15] (15,20] (20,25] (25,30] 

I am concerned these vegetation classes are not grouped probably and there
is overlap between the classes. It should read, preferably without brackets
or only one kind (): 
(-5-0) (1-5) (6-10) (11-15) (16-20) (21-25) (26-30)

How do I fix this?
Please advise, Jean
