Exploration of the relationship between a response and a single predictor

A convenience function for generating exploratory graphs and numeric summaries, regression analysis output, and the residual analysis of the simple linear model.

Usage

OnePredictor(Response, Predictor, Data = NULL, 
    Filename = NULL, Folder = NULL, 
    VI = getOption("BrailleR.VI"), Latex = getOption("BrailleR.Latex"), 
   View = getOption("BrailleR.View"), Modern=TRUE)

Arguments

Response: Name of the continuous response variable.
Predictor: Name of the continuous response variable.
Data: The data.frame that contains both the response and the factor.
Filename: Name of the Rmarkdown and HTML files to be created. A default will be created that uses the names of the variables if this is left set to NULL.
Folder: Name of the folder to store graph and LaTeX files. A default will be created based on the name of the data.frame being used.
VI: Logical: Should the VI method for blind users be employed?
Latex: Logical: Should the tabulated sections be saved in LaTeX format?
View: Logical: Should the HTML file be opened for inspection?
Modern: Logical: Should the graphics be created using ggplot?

Details

This function writes an R markdown file that is knitted into HTML and purled into an R script. All graphs are saved in subdirectories in png, eps, pdf and svg formats. Tabulated results can be stored in files suitable for importing into LaTeX documents.

Value

This function is used for creation of the files saved in the working directory and a few of its subdirectories.
