r2htmlBiv (or r2hb in short) performs some bivariate analyses, then generates code to be
included in a HTML document in order to print out the analyses on a Web page.r2hb(formula,fileOut="",textBefore="",textAfter="",graphDir="graphBiv",graphName="V",type="png",displayStyle=7,limDiscreteY=10,limDiscreteX=10)
r2htmlBiv(formula,fileOut="",textBefore="",textAfter="",graphDir="graphBiv",graphName="V",type="png",displayStyle=7,limDiscreteY=10,limDiscreteX=10)[variable~variable] or [variable~data.frame] : contains the
data to analyse. In all the following, the left part will be called
Y, the right part will be X.[character]

the HTML summary will be saved. If empty, the HTML code is printed on screen.[character] or [vector(character)] : before
printing a variable analysis, r2hb can write a
text. If X is a single variable,
textBefore should be of length 1. If X is a d[character] or [vector(character)] : same
as textBefore but the text is printed after the variable
analysis. See textBefore and examples for details.[character] :

r2hb proposes two different ways of displaying the results.
The first one is compact, it displays all the results on two lines. If the
number of modalities of X[numeric] : r2hb distinguishes two
kinds of numeric variables:
discrete designates numeric variables with only a few
modalities, continuous designates nume[numeric] or [vector(numeric)]: same
as limDiscreteY. If X is a data.frame, limDiscreteX can have the same
length as X or can be of length 1 (and is recycr2hb generates HTML code and either prints it on the screen, or saves it in a
file. It also generates several graphs, optionally
in a different directory.r2hb goes through the following steps:
data.frame).
Step 2. Optionally, set some variables as ordered.
Step 3. Run r2hb(Y~dataFrame,"fileOut.html").

See examples of application.r2hb performs some basic analyses, then generates
code to be included in a HTML document in order to print out the analyses in a
Web page.
r2hb performs the analyses automatically according to the
data class. It considers 5 classes: nominal with 2 modalities,
nominal with 3 modalities or more, ordered, discrete and
continuous (see the description of limDiscreteY for details on
discrete and continuous).
The analysis of the variable depends on the class of Y and
X wich gives 25 possible combinations. We will not give a
description here, all of them are presented in the pdf file Yis continuous andXhas

YandX. Note that as
many tests as possible are run. For example, ifYis nominal
andXis ordered,Xcan be considered as
a factor (khi2 and Fisher exact test) but also as a discrete variable (Wilcoxon).X is a data.frame, r2hb runs the analyses on
every column.

### Create some data
V1 <- factor(LETTERS[floor(runif(50,1,4))])
V2 <- rnorm(50,1,1)<0
V3 <- ordered(LETTERS[floor(runif(50,1,4))])
### Create a directory for the output
if(!file.exists("tmp/r2hbExample",recursive=TRUE)){dir.create("tmp/r2hbExample",recursive=TRUE)}else{}
setwd("tmp/r2hbExample")
### Execute r2hb
