TwoFactors {BrailleR} R Documentation

## A convenience function for a two-way analysis

### Description

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"))


### 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?

### Examples

DIR = getwd()
setwd(tempdir())
TG <- ToothGrowth
TG$dose <- as.factor(TG$dose)

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

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

# For unbalanced data
TG_Unb <- TG[-c(53:60),]
TwoFactors('len', 'supp', 'dose', Data=TG_Unb, Inter=TRUE)
rm(TG); rm(TG_Unb)
# N.B. Various files and a folder were created in a temporary directory.
# Please investigate them to see how this function worked.
setwd(DIR)
