I'm trying to create a custom ggplot2 geom by modifying
geom_errorbar function uses an operator that I've never seen before
%||%, on line 37 here:
does anyone know what it is, and which package define it? Trying to run my custom geom I get the error:
Error in data$width %||% params$width %||% (resolution(data$x, FALSE) * (from geom_errorbar2.R#40) :
could not find function "%||%"
