plt_labeled_pts: Plot scattered labeled points.

In cabaceo/shinymod: Reusable Shiny Modules and Helper Functions

Plot scattered labeled points.

Description

Visualize a blob of 2-D data points in space, with nearly non-overlapping labels for the points.

Usage

plt_labeled_pts(
  df,
  xvar,
  yvar,
  pt_label_var,
  title = "Multidimensional Scaling Result",
  repel_force = 10
)

Arguments

df	Data frame. Its rows are points and columns are dimensions.
xvar	String. Name of the variable to be put on the x-axis.
yvar	String. Name of the variable to be put on the y-axis.
pt_label_var	String. Name of the variable to label the points.
title	String. Plot title (default = "Multidimensional Scaling Result").
repel_force	Integer. Force of repulsion between overlapping text labels. Defaults to 10. If this value is too small, the labels often won't be repeled hard enough to completely avoid overlapping.

Value

A ggplot2 scatterplot with labeled points.

Examples

mtcars$car_types = row.names(mtcars)
plt_labeled_pts(mtcars, xvar = 'mpg', yvar = 'wt', pt_label_var = 'car_types')
