Dear all,
I'm having trouble getting the correct spacing between x-axis labels on a
barplot. This is the command I'm using to generate the plot:
temp <- barplot(precip, beside=TRUE, xaxt="n", las=1, xpd=FALSE, col="grey28",
ylim=c(0, max(precip)))
Here is the structure of temp:
> str(temp)
num [1:96, 1] 0.7 1.9 3.1 4.3 5.5 6.7 7.9 9.1 10.3 11.5 ...
And here is the structure of the data being plotted:
> str(precip)
num [1:96] 1841 2871 9254 22335 30682 ...
> length(precip)
[1] 96
These are monthly data points for 8 years (8 * 12 = 96), but I only want to
have labels for each year (1978 to 1985), rather than every month. So I tried
using the following command, but this results in the labels not being far
enough apart, and therefore they don't fill the length of the x-axis (and don't
align properly with the corresponding first bar of every year):
axis(1, at=seq(1,96,12), 1978:1985)
This one has stumped me somewhat, so I'd be grateful to receive any suggestions
as to how I might resolve this.
Many thanks,
Steve
