barplot problem

Hello- I am having trouble making a barplot... The y-values are: data=c(-0.0002129061,0.0000000000,-0.0002699561,0.0163883061,0.0400000000). The x-values are distance=c(0, 71, 172, 206, 292). The desired x-range is 0 and ~300+ (kilometers), range=seq(0,300,1) I would like to make a bar plot with the bar locations along the x-axis spaced according to their distances. I have tried barplot(distance, data)... but this produces a very strange plot. plot(distance, data) is almost correct, except it is a scatter plot. Thanks for any help you can provide, I must be missing something very obvious.
Hi Jack, You can use the space argument in barplot to do this by running barplot with equally spaced bars, and getting the x positions of the bars in the return values. Then just space the bars out as needed with a vector of "space" values. This should give you a reasonable looking x axis, but you might have to pass the cumulative sum of bar positions and spaces if you want each bar labelled. Jim
