## 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. Take care, -jh         [[alternative HTML version deleted]] ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.

## Re: barplot problem

 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.

## Re: barplot problem

 Hi Jim- Thanks for your help.  I am not sure how to execute your instructions... I used the space argument to to equally space the bars (barplot(data, space=c(1,1,1,1,1,1)). How do I get the "x positions in the return values".  Take care, -jh On Sun, May 27, 2012 at 3:42 AM, Jim Lemon <[hidden email]> wrote: > On 05/27/2012 01:26 PM, jack hietpas 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. >> >>  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 take a look into xp. See also ?barplot!

## Re: barplot problem

 In reply to this post by jhmicro 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 <[hidden email]> 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]] > > ______________________________________________ > [hidden email] mailing list > https://stat.ethz.ch/mailman/listinfo/r-help> PLEASE do read the posting guide > http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >         [[alternative HTML version deleted]] ______________________________________________ [hidden email] mailing list https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.
