visualise_variables_xx: Visualise each Variable Pair in a given Dataset

In oislen/BuenaVista: Functions for Everyday Data Science Tasks

Description

Plots an appropriate visualisations for two attributes in a given dataset. This function utilises ggplot2 to design and plot the Visualisations. Plots a scatterplot for two numeric variables. Plots a bar chart for two factor variables. Plots a boxplot for one numeric variable and one categorical variable. The plots can be standardised, whereby the values lie on the interval 0 to 1. By default, regular plots are visualised. There is also an option to click through the points one by one, or print them all simultaneously. The plots are outputed as a list. The plots can also be saved to a specified directory as pdfs. Note, that it is crucial that the variables are correctly defined as either numeric or categorical.

Usage

visualise_variables_xx(dataset, y_index = NULL, y_name = NULL,
  click = TRUE, standardise = FALSE, directory = NULL)

Arguments

dataset	The dataset to be visualised. Note, appropriate data types must be defined for the columns.
y_index	An integer value, indicating the column index of the response variable, the default is NULL.
y_name	A character value, indicating the column name of the response variable, the default is NULL.
click	A boolean value, indicating whether to click through the plots one by one, default is True,
standardise	A logical value, indicating whether the axises should be standardised to the interval 0 to 1, the default is False.
directory	A character object specifying the directory where the data frame is to be saved as a .pdf file.

Value

Outputs a variety of bar charts, histograms and bar charts.

Examples

#-- Example 1: LungCap Data --#

# Regular Visualisations of the data frame
visualise_variables_xx(dataset = lungcap, click = TRUE)

Regular visualistions of the data using y_name
visualise_variables_xx(dataset = lungcap, y_name = 'Gender')

# Standardised Visualtions of the dataset
visualise_variables_xx(dataset = lungcap, standardise = TRUE, click = FALSE)

# Standardised Visualisations of the data frame using y_index
visualise_variables_xx(dataset = lungcap, standardise = TRUE, y_index = 1)

#-- Example 2: Titanic Data --#

# Regular Visualisations with click option
visualise_variables_xx(dataset = titanic, click = TRUE)

Regular visualistions of the data using y_name
visualise_variables_xx(dataset = titanic, y_name = 'Gender', click = TRUE)

# Standardised Visualtions of the dataset
visualise_variables_xx(dataset = titanic, standardise = TRUE, click = FALSE)

visualise_variables_xx(dataset = titanic, standardise = TRUE, y_index = 1)
