Histogram

Description

Create a histogram

Usage

histogram(
  vector = NULL,
  number_of_bins = 30,
  x_tick_marks = NULL,
  y_tick_marks = NULL,
  fill_color = "cyan4",
  border_color = "black",
  y_axis_title_vjust = 0.85,
  x_axis_title = NULL,
  y_axis_title = NULL,
  cap_axis_lines = FALSE,
  notify_na_count = NULL
)

Arguments

vector

a numeric vector

number_of_bins

number of bins for the histogram (default = 30)

x_tick_marks

a vector of values at which to place tick marks on the x axis (e.g., setting x_tick_marks = seq(0, 10, 5) will put tick marks at 0, 5, and 10.)

y_tick_marks

a vector of values at which to place tick marks on the y axis (e.g., setting y_tick_marks = seq(0, 10, 5) will put tick marks at 0, 5, and 10.)

fill_color

color for inside of the bins (default = "cyan4")

border_color

color for borders of the bins (default = "black")

y_axis_title_vjust

position of the y axis title (default = 0.85).

x_axis_title

title for x axis (default = "Value")

y_axis_title

title for y axis (default = "Count")

cap_axis_lines

logical. Should the axis lines be capped at the outer tick marks? (default = FALSE)

notify_na_count

if TRUE, notify how many observations were removed due to missing values. By default, NA count will be printed only if there are any NA values.

Value

the output will be a histogram, a ggplot object.

Examples

histogram(1:100)
histogram(c(1:100, NA))
histogram(vector = mtcars[["mpg"]])
histogram(vector = mtcars[["mpg"]], x_tick_marks = seq(10, 36, 2))
histogram(vector = mtcars[["mpg"]], x_tick_marks = seq(10, 36, 2),
y_tick_marks = seq(0, 8, 2), y_axis_title_vjust = 0.5,
y_axis_title = "Freq", x_axis_title = "Values of mpg")
