aes_string

From ggplot2 v0.9.3.1 by Hadley Wickham

Generate aesthetic mappings from a string

Aesthetic mappings describe how variables in the data are mapped to visual properties (aesthetics) of geoms. Compared to aes this function operates on strings rather than expressions.

Usage

aes_string(...)

Arguments

...: List of name value pairs

Details

aes_string is particularly useful when writing functions that create plots because you can use strings to define the aesthetic mappings, rather than having to mess around with expressions.

Examples

aes_string(x = "mpg", y = "wt")
aes(x = mpg, y = wt)

``` # define a function to create a scatterplot, allowing user to specify what to put on x- and y-axes: plot.fn.with.aes <- function(df, x.axis, y.axis, point.colour = NULL) { ggplot(df, aes_string(x = x.axis, y = y.axis, colour = point.colour)) + geom_point() } # test the function: plot.fn.with.aes(mtcars, "mpg", "cyl") plot.fn.with.aes(mtcars, "mpg", "cyl", "gear") ```
