scatter_chart: Create scatter chart

In pgarnry/ggplotHelper: Helper functions for great looking ggplots in R

Description

This function is a convinient overlay for creating a beautiful scatter plot using ggplot2

Usage

scatter_chart(data, x, y, na.rm = FALSE, name.label = NULL,
  name.labels.show = NULL, label.just = NULL, title = NULL,
  sub.title = NULL, y.title = NULL, x.title = NULL, x.min = NULL,
  x.max = NULL, y.min = NULL, y.max = NULL, prediction.interval = FALSE,
  ...)

Arguments

data	data frame containing data for plotting
x	character string specifying name of x variable in data frame
y	character
na.rm	a logical indicating whether NA values should be removed
name.label	character string specifying column name of names for textual annotations
name.labels.show	numeric or character string indicating either the number of label names to show or the specific names (details)
label.just	numeric vector with length two setting the horizontal and the vertical text alignment for data point labels
title	character string specifying chart title
sub.title	character string specifying chart sub title
y.title	character string specifying y-axis title
x.title	character string specifying x-axis title
x.min	numeric setting minimum limit on x-axis
x.max	numeric setting maximum limit on x-axis
y.min	numeric setting minimum limit on y-axis
y.max	numeric setting maximum limit on y-axis
prediction.interval	logical indicating whether a prediction interval should be computed and ploted

Details

If the name.labels.show is numeric the data point labels shown are based on the distance between actual and fitted y-values. If the variable is set to 3 then the three points with largest absolute distance between actual y-values and the fitted values will have their name shown. This functionality requires that the prediction.interval is set to TRUE. If the name.labels.show is a character string then names are explicitly shown in the scatter plot.

Examples

data(mtcars)
density_chart(mtcars, "mpg", "cyl", title = "Miles per gallon",
sub.title = "(per groups of cylinders)", vline = TRUE)
