Add ggplot instructions to create brushes and lassos for both saved and active multiple selections in a DotPlot panel.
Arguments
- x
An instance of a DotPlot class.
- envir
The environment in which the ggplot commands are to be evaluated.
- commands
A character vector representing the sequence of commands to create the ggplot object.
- flip
A logical scalar indicating whether the x- and y-axes are flipped, only relevant to horizontal violin plots.
Value
A character vector containing commands plus any additional commands required to draw the self selections.
Details
This is a utility function that is intended for use in .generateDotPlot.
It will modify envir by adding all_active and all_saved variables,
so developers should not use these names for their own variables in envir.
If no self-selection structures exist in x, commands is returned directly without modification.
