Thanks!

Yes, but I also want to be able to condition easily hence
histogram(...), not plot

You might consider something based on the concept of:

   y <- table( x)
   plot( as.numeric(names(y)) , y, type='h')

[R] histogram for integer data

2008-03-27 Thread Erwann.Rogard
hi,
 
library(lattice)
x<-c(-1,-1,-1,0,0,0,0,1,1,2)
rng<-range(x)
histogram(x,endpoints=c(rng[1]-0.5,rng[2]+0.5),nint=length(unique(x)))
 
instead of contiguous bins, i'd like spaces between them to indicate
that the data is discrete, or even better, line segments positioned at
integer values.
i know how to do this with plot, but i need it with histogram, so that
in more complicated contexts i can use histogram(~x| f1 * f2)
 
thanks!
