AsIs aesthetics

[schloerke]

I'm trying to use aesthetics with the AsIs function to use values as they are.

library(ggplot2)

ggplot(data = iris, aes(Sepal.Length, Sepal.Width)) + geom_point(aes(size = I(5)))
# Error in data.frame(size = 5, PANEL = c(1L, 1L, 1L, 1L, 1L, 1L, 1L, 1L,  : 
  arguments imply differing number of rows: 1, 150

# thought process... produces error.  ok, I can make it longer.  trying again.
ggplot(data = iris, aes(Sepal.Length, Sepal.Width)) + geom_point(aes(size = I(rep(5, nrow(iris)))))

This produces a plot that is treated as a true value, rather than AsIs.

How can I make something a 'parameter' through the use of aes()?

You can't, unless you use ggvis.

You have to either move it outside of the aes() or use scale_size_identity()

Oh hmm, I made it work because it turned out to be easy
