The basic problem is that hist() is really designed for continuous data,
and you're using it with discrete data. You can either say
r <- rbinom(100000,10,0.5)
hist(r,10,0.5),col=2,xlim=c(0,10),ylim=c(0,30000),
breaks=seq(-0.5,10.5,by=0.1))
so that the bins span (-0.5 to 0.5, 0.5 to 1.5, ...)
or (arguably better, because it is more sensible with discrete data)
barplot(table(r),space=0)
## note that if you're building tables of sparser data where all
## levels may not be represented you may want something like
barplot(table(factor(r,levels=0:10)),space=0)
# instead

I have a modified version of the plot.histogram that also takes the two arguments width and offset. This might be what you are looking for. See the Rd-page at: http://www.maths.lth.se/matstat/bioinformatics/software/R/library/R.base/html/plot.histogram.html The function can be downloaded at http://www.maths.lth.se/matstat/staff/hb/mypackages/R/plot.histogram.R I haven't used it in a while, but I wrote it to be able to place two or more histograms in the same plot.
