Prepares an analysis of a data set with one response and two predictors that are both factors. An interaction between the two factors is also allowed for. The function creates a number of graphs and tables relevant for the analysis.

Usage

TwoFactors(Response, Factor1, Factor2, Inter = FALSE, HSD = TRUE, 
   AlphaE = getOption("BrailleR.SigLevel"), 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.

Factor1, Factor2

Name the two factors to be included.

Inter

Logical: Should the interaction of the two factors be included?

HSD

Logical: Should Tukey's HSD be evaluated for the data?

AlphaE

The family-wise Type I error rate for Tukey's HSD calculations.

Data

Name the data.frame that includes the three variables of interest.

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?

Examples

DIR = getwd()
setwd(tempdir())
if(require(dplyr)){
TG <- ToothGrowth |> mutate(dose = as.factor(dose))

# Without interaction
TwoFactors('len','supp','dose',Data=TG, Inter=FALSE)

# With two-way interaction
TwoFactors('len', 'supp', 'dose', Data=TG, Inter=TRUE)

rm(TG); rm(TG)
