| cat_offset {rbokeh} | R Documentation |
Add an offset to a categorical variable for Bokeh plotting.
cat_offset(x, offset)
x |
The categorical data to offset, a vector of categorical / factor data. |
offset |
A numeric vector of matching length of |
This function allows specification of plotting values in between two categorical values. Suppose, for example, a categorical axis has axis ticks ordered "a", "b", "c". Then plotting cat_offset("a", -0.5) will plot a value halfway between "a" and "b", while plotting cat_offset("a", 0.5) will plot a value halfway between "b" and "c".
