I have solved the problem by introducing an artificial variable in the original
I have a large data-frame with measurements such as:
id i v1 v2 v3

three variables) I want to compute the median

Hello,
What would you recommend for producing publication-quality plots with R?
Built-in graphics, trellis, ggplot2, or something else?
Basic requirements:
- I need to draw line-, box-, density-plots, bar-charts and histograms
- error bars on bar- and box-plots
- easy tiling of multiple plots
