x <- element_text(size = 15)
update_element(x, colour = "red")
# Partial matching works
update_element(x, col = "red")
# So does positional
update_element(x, "Times New Roman")
# And it throws an error if you use an argument that doesn't exist
update_element(x, noargument = 12)
# Or multiple arguments with the same name
update_element(x, size = 12, size = 15)
# Will look up element if given name
update_element("axis.text.x", colour = 20)
# Throws error if incorrectly named
update_element("axis.text", colour = 20)Run the code above in your browser using DataLab
