createPolygons | R Documentation |
Create a data set of polygons for a set of letters from a specified fontfamily
createPolygons(letters, font, fontsize = 400, dim = c(720, 720), scale = FALSE)
letters |
set of characters for which polygons are to be created |
font |
character describing the name of a font - use e.g the command 'extrafont::fonts()' to check on available fonts and installing other fonts. |
fontsize |
size of letter to be created - larger means higher resolution, but also bigger result sets |
dim |
dimensions of the box in which the created letter is supposed to fit |
scale |
scale the values along the y axis to use result in geom_logo |
data set compatible to work with geom_logo
# check that all letters and digits are nicely shaped:
new_alphabet <- createPolygons(c("f", "g", "W", "*"), font="Garamond")
library(ggplot2)
qplot(x,y, geom="polygon", data=new_alphabet, facets=~group)
