Plot by group

[antagomir]

The plotSeries function can be used to plot and compare several taxa over e.g. time.

But sometimes we need to plot and compare several individuals / subjects over time w.r.t. one taxa, or another variable like alpha diversity.

Suggestion to implement a function that allows handy comparison of multiple time series from different groups.

Along these lines

ggplot(as.data.frame(colData(tse)), aes(x = time, y=shannon, group = subject)) + geom_line()

but allowing one to easily choose any given numeric colData field, or taxonomic group on the Y axis, as a handy wrapper:

plotSeries(tse, x=time, y=selected.field, group=subject, ....)
