OneFactor {BrailleR} R Documentation

## Analysis for a continuous response for one group factor

### Description

A convenience function that creates an analysis for a continuous response variable with one grouping factor. The function creates a number of graphs and tables relevant for the analysis.

### Usage

OneFactor(Response, Factor, Data = NULL, HSD = TRUE, AlphaE = 0.05,
Filename = NULL, Folder = NULL,
VI = getOption("BrailleR.VI"), Latex = getOption("BrailleR.Latex"),
View = getOption("BrailleR.View"))


### Arguments

 Response Name of the continuous response variable. Factor The grouping factor. Data The data.frame that contains both the response and the factor. HSD Logical: Should Tukey's HSD be evaluated for the data? AlphaE The family-wise Type I error rate for Tukey's HSD calculations. 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?

### 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 are 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.

### Examples

DIR = getwd()
setwd(tempdir())
data(airquality)

# the following line  returns an error:
## OneFactor("Ozone", "Month", airquality, Folder=tempdir(), View=FALSE)
# so we make a copy of the data.frame, and fix that:

airquality2 = airquality
airquality2$Month = as.factor(airquality$Month)
# and now all is good to try:
OneFactor("Ozone", "Month", airquality2)
# N.B. Various files and a folder were created in a temporary directory.
# Please investigate them to see how this function worked.
setwd(DIR)
