pass character strings to ggplot2 within a function

Question

Often I use ggplot2 in my work and build wrapper functions to speed up my work flow. The use of the non-standard evaluation (NSE) aes forces me to use the actual variable n

Answer 1

There's the aes_string function, that I don't really see given prominence, which does exactly this:

FUN <- function(dat, x, y) {
    ggplot(dat, aes_string(x = x, y = y)) +
        geom_point()
}

FUN(mtcars, "mpg", "hp")
