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. Take care, -jh [[alternative HTML version deleted]]
It sounds like you want something of the form plot(distance, data, type = "h") But the lines might be too thin: try adding lwd = NUM to increase the thickness.

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
I would use barchart in lattice. To get control of spacing you need to use the panel.barchart with the xyplot function. I show two options below. The first labels the distance scale with the default values seq(0,300,50), The second labels the bars with their distance value. tmp <- data.frame(y=c(-0.0002129061,0.0000000000,-0.0002699561,0.0163883061,0.0400000000), distance=c(0, 71, 172, 206, 292)) xyplot(y ~ distance, data=tmp, horizontal=FALSE, origin=0, panel=panel.barchart, box.width=20) xyplot(y ~ distance, data=tmp, horizontal=FALSE, origin=0, panel=panel.barchart, box.width=20, scales=list(x=list(at=tmp$distance))) On Sat, May 26, 2012 at 11:26 PM, jack hietpas <mikroskop@gmail.com> wrote:> 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. > > Take care, > > -jh > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html<http://www.r-project.org/posting-guide.html> > and provide commented, minimal, self-contained, reproducible code. >[[alternative HTML version deleted]]
