Ista:
Your attached code did work for me; moreover, the facets were presented in
the desired order with facet_wrap() and facet_grid(), which is what I'm
using because I have a second factor used in facet_grid().
Still, my plots with total.density as a facet are coming out in 16, 32, 8,
and I'm not seeing why. Below is my plot code -
ggplot(ag.tab[ag.tab$plant.sp == 'EC',], aes(x = days.out, y = per.remain))
> + facet_grid(total.density ~ prop.ec) +
> #add point and error bar data
> theme_set(theme_bw()) +
> geom_point() + geom_errorbar(aes(ymin = per.remain - se, ymax =
> per.remain + se), width = 3) +
> #add predicted model data
> geom_line(data = se.predict.data[se.predict.data$plant.sp == 'EC',],
> aes(x = x.values, y = predicted.values), colour = c('red')) +
> geom_line(data = dc.predict.data[dc.predict.data$plant.sp == 'EC',],
> aes(x = x.values, y = predicted.values), colour = c('blue'), linetype =
> c('dashed')) +
>
> xlab('Day') + ylab('Percent Mass Remaining') + opts(panel.grid.major =
> theme_blank(), panel.grid.minor = theme_blank())
Is there anything odd about it that might be producing the odd ordering
problem? FYI, avoiding subsetting ag.tab doesn't do the trick.
