Convert units
1 | convert_length(x, unit = c("mm", "cm", "inches"))
|
x |
a numeric vector |
unit |
supported units, only "mm", "cm", "inches". |
This function coverts mm/cm/inches units to units measured in the canvas coordinate, e.g. how much is it in the canvas coordinate for 1 mm/cm/inches.
Since in the circular plot, the aspect ratio is always 1, it does not matter this conversion is applied on x direction or y direction.

convert_x
and convert_y
convert absolute units into a data coordinate in a specified cell.
