Dear list,
I am new to R and trying to create a grouped (four groups) scatter plot
with error bars (only in y-direction) using the scatterplot() function
from the car package.
The code I am using for plotting the scatter plot is:
scatterplot(a$s_profile~a$s_plot | a$group, data=a)
which gives me a nice grouped scatter plot. However I have no idea how
to insert error bars. Using errbar() from the Hmisc Package gives some
unwanted results, e.g. adding new points with an offset in xy(!?) even
when specifying the xlim/ylim parameters.
Another problem is to move/orientate the plotted legend individually, is
there any possibility?
I would appreciate your help in solving my problems.
Many thanks in advance,
Philip
