Hello,
I am just starting out using R on my Uni course. I have been given a function
to work with that adds error bars to a bar chart. I want to add a legend and
have been trying to amend the code in the function error.bars (see below) so it
automatically places a legend on the chart. It does this, but the legend is
sitting over the top of one of my data columns. I need the function to decide
where best to place the legend, depending on where the chart bar data and error
bars are located. Is it possible to do this?
Hi Sarah,
The "emptyspace" function in the plotrix package can find the empty
space on a bar chart, but would need a little modification to avoid
error bars. You could feed it the bar heights plus the error bars, but
that might not be automatic enough.
