cont_hist_list is a vectorized version of cont_hist. pm_histogram is a generic histogram function that is called by other functions in pmplots.

cont_hist(
  df,
  x,
  xs = defx(),
  y = "count",
  add_density = y == "density",
  add_layers = TRUE,
  ...
)

cont_hist_list(df, x, ...)

pm_histogram(
  ...,
  col = opts$histogram.col,
  fill = opts$histogram.fill,
  alpha = opts$histogram.alpha
)

Arguments

df

the data frame containing plotting data.

x

the x column for ggplot2::geom_histogram().

xs

a list of information for the x axis.

y

what to use for the y-axis on the histogram; can be "count" or "density".

add_density

if TRUE, a normal density line will be plotted over the histogram using add_density().

add_layers

extra layers will be added only if TRUE.

...

passed to ggplot2::geom_histogram() and add_density().

col

a character value passed to ggplot2::geom_histogram().

fill

a character value passed to ggplot2::geom_histogram().

alpha

a numeric value passed to ggplot2::geom_histogram().

Value

A single plot.

Examples


data <- data.frame(WT = rnorm(1000,80,20))

cont_hist(data, x = "WT//Weight (kg)")
#> `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.
