[R] Visualize quartiles of plot line

[Arne Brutschy]

Hello,

I'm currently using a simple plot to visualize some mean values. I'm
having ~200 datapoints on the x-axis, each has 10 records. I'm
currently plotting only the mean value of each of the datapoints.

What I need is a way to visualize the quartiles/error/whatever of
these points. I thought about boxplots, but I have to many points on
the xaxis - it would be impossible to see anything. I though that it
would be nice to have a "hull" around each line, indicate the width of
the quartiles, visualized by a different background. It's like a very
wide boxplot with a changing mean value...

Is this possible with r? Does anyone know what I mean and/or has done
this before?

Thanks
Arne
