Re: [R] Removing inter-bar spaces in barchart
Using the barplot function in base graphics you just set space=0, but that function does not have a box.ratio argument which would imply that you are using something else. If you let us know which function (and which package it is in) then it is easier (possible) for us to help you, even better is to give the information asked for at the bottom of every post and the posting guide. -- Gregory (Greg) L.

I'm more interested in why you'd 'ideally want zero space between the bars'. By default, bar chart functions in R have spaces between bars because the bars represent different categories of a discrete/factor variable and the space is a visual device meant to connote to the viewer that the categories are not to be interpreted as an underlying continuum. In contrast, there are no spaces in between bars of a histogram precisely because the x-scale is meant to be continuous. Since you're using barchart(), why do you want to remove the space between bars? Cheers, Dennis --j -- Jonathan A.
