cytofan
implements the concept of fan plots (Britton,
E.; Fisher, P. & J. Whitley (1998) The Inflation Report Projections:
Understanding the Fan Chart) for cytometry data in ggplot2.
The cytofan
package was implemented following up on a gist
written shortly after the fanplot
package was released. Compared to ggfan,
cytofan
uses categorical data as input on the x axis.
You can install cytofan from github with:
# install.packages("devtools")
::install_github("yannabraham/cytofan") devtools
cytofan
can be used to visualize differences between
populations identifed using mass
