Hello List,
I got an error message when I submit the code below
ggplot(eth, aes(ymax=ymax, ymin=ymin, xmax=4, xmin=3, fill=ethnicity)) +
geom_rect() + coord_polar(theta="y") + xlim(c(2, 4) )
Error: `data` must be a data frame, or other object coercible by `fortify()`,
not an S3 object with class rxlsx
I checked the syntax. But I can not find any error on my code. Can you help me
to find where is the problem?
Thanks
