[R] lineplot.CI problem

[Dieter Vanderelst]

Hi,

Thank you very much for this very rapid and helpful reply.

I'm giving the code a spin around the block. It looks to be working fine.

There is actually also something else on my lineplot.CI wish list. If I might be so bold to ask:

When plotting multiple data traces with relative high standard deviations, the whiskers tend to overlap. This hampers the interpretation of the data somewhat. Is there a way to let the function plot data points with some horizontal displacement to prevent this?

Regards,

Dieter
