Create a data set of polygons for a set of letters from a specified fontfamily

Description

Create a data set of polygons for a set of letters from a specified fontfamily

Usage

createPolygons(letters, font, fontsize = 400, dim = c(720, 720), scale = FALSE)

Arguments

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

Value

data set compatible to work with geom_logo

Examples

# 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)
