gf_function | R Documentation |
These functions provide two different interfaces for creating a layer that contains the graph of a function.
gf_function(object = NULL, fun, xlim, ..., inherit = FALSE) gf_fun(object = NULL, formula, xlim, ..., inherit = FALSE)
object |
When chaining, this holds an object produced in the earlier portions of the chain. Most users can safely ignore this argument. See details and examples. |
fun |
A function. |
xlim |
A numeric vector providing the extent of the x-axis when creating the first layer in a plot. Ignored when creating a subsequent layer. |
... |
Other arguments such as |
inherit |
A logical indicating whether default attributes are inherited. |
formula |
A formula describing a function. See examples and |
gf_function(fun = sqrt, xlim = c(0, 10)) gf_dhistogram(~age, data = mosaicData::HELPrct, binwidth = 3, alpha = 0.6) %>% gf_function( fun = stats::dnorm, args = list(mean = mean(mosaicData::HELPrct$age), sd = sd(mosaicData::HELPrct$age)), color = "red" ) gf_fun(5 + 3 * cos(10 * x) ~ x, xlim = c(0, 2)) # Utility bill is quadratic in month? f <- makeFun(lm(totalbill ~ poly(month, 2), data = mosaicData::Utilities)) gf_point(totalbill ~ month, data = mosaicData::Utilities, alpha = 0.6) %>% gf_fun(f(m) ~ m, color = "red")
