Marker Transparency

[samhinman]

Thank you for generating this package - I'm excited about the possibilities it opens for interpreting my data!

I would like to render the datapoints/markers semi-transparent (alpha < 1) so that overplotted data will be easier to visualize. I have attempted using the following arguments, based on code from the readme, tutorial, and manual files, though have not had any luck. I do not receive any errors using the following code, though the transparency of the data points in the plot is not altered.

plot(unpaired_mean_diff, rawplot.type = "swarmplot", palette = c(rgb(0, 0, 0, 0.2), alpha("sienna4", 0.2)))

plot(unpaired_mean_diff, rawplot.type = "swarmplot", palette = c(rgb(0, 0, 0), "sienna4")) + geom.quasirandom(alpha = 0.2)

I have also attempted utilizing the swarmplot.params argument (from geom_quasirandom()link), though receive the error, "Error in plot.dabest_effsize(unpaired_mean_diff, rawplot.type = "swarmplot", : swarmplot.params is not a list."

plot(unpaired_mean_diff, rawplot.type = "swarmplot", palette = c(rgb(0, 0, 0), "sienna4"), swarmplot.params = (alpha = 0.2))

Interestingly, if I change the plot type to "sinaplot", alpha can be changed through the palette argument, though the group width becomes rather thin and is not responsive to the rawplot.groupwidth argument.

plot(unpaired_mean_diff, rawplot.type = "sinaplot", rawplot.groupwidth = 1, palette = c(rgb(0, 0, 0, 0.2), alpha("sienna4", 0.2)))

I am currently toubleshooting through RStudio v1.3.1056 and dabestr v.0.3.0 with the iris dataset. As I'm relatively new to R, I would like to know whether I am missing a simple argument or command, or whether there is a bug and/or workaround? Any advice would be appreciated!

Workaround: Was able to enable marker transparency in the swarmplot by routing through a geom_quasirandom list (via the swarmplot.params argument). Marker size then had to be adjusted in the same list, as it was no longer responsive through the plot() function.

swarmplot.custom.params <- list(alpha = 0.3, size = 3)
plot(unpaired_mean_diff, rawplot.type = "swarmplot", palette = c(rgb(0, 0, 0), "sienna4"), swarmplot.params = swarmplot.custom.params)
