Generate a histogram plot

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 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 geom_histogram and add_density
col	a character value passed to geom_histogram
fill	a character value passed to geom_histogram
alpha	a numeric value passed to 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`.
