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

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.

Hope this helps,
Michael

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.

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,

xp <- barplot(.....)

Then take a look into xp.

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)))

Re: barplot problem

Richard- thank you very very much, this is exactly what I needed. I have
not previously used lattice graphics, I will have to experiment more with
this package.

Also thanks to everyone for your input.
