Hi, I'm using the hist function to plot the frequency of 21 variables, but it keeps starting the x-axis from 0 and adding variables 1 and 2 together (all other vairables have the correct frequencies). I suspect it adds 1 and 2 together so that 0 can fit in with demarcations at intervals of 5. Using "xlim=c(1,21)" to specify that i don't want to include 0 and using the "breaks" command to specify 21 breaks doesn't help. Any advice? Thank you!! -- View this message in context: http://r.789695.n4.nabble.com/Histogram-not-plotting-correct-breaks-tp2066057p2066057.html Sent from the R help mailing list archive at Nabble.com.
trying setting br = 40 inside the hist, and check if that helps...

What do you expect to happen to values that fall exactly on the boundary? I have seen questions similar to yours that come about because the user expects different from what the computer does. Look at the 'right' argument to the hist function for a way to change this and see if that helps. -- Gregory (Greg) L.
