ActivityOverlap with more than 2 species

[Raphaelle Abn]

Hi, 

I would like to plot the diel activity of 5 species on the same graph to see the differences. I noticed that the function ActivityOverlap only allows the overlap of 2 speices curves. Does anyone has an idea of another method to make a multi-species activity plot ? Thanks !

As far as I know it's not possible with overlap() as yet. However, follow this tutorial, it should do what you want using ggplot2:

Just an ugly workaround, but you could use the output of activityOverlap(), which is a data frame with 3 columns (time, density species A, density species B).

Do that for all relevant species, name the columns, then combine the data frames via cbind, melt (to convert from wide to long format), then plot with ggplot2.

Alternatively, you could use the densityPlot function from overlap, which also returns a data frame of time and density for further plotting.

Best,

J
