hTest: hTest

In sontron/madis: Manipulating and Analyzing Data Interactively with Shiny

Description

hTest provides some basic hypothesis statistical tests, and can detect which test method should be used based on the variable modes and distribution of continuous variables.

Usage

hTest(data, xvars, yvars = "", alter = c("two.sided", "less",
  "greater")[1], paired = FALSE, confLevel = 0.95, nullHyp = 0,
  normalSampleSize = 30, Digits = 4)

Arguments

data	data.frame
xvars	variables on the right hand side.
yvars	variables on the left hand side. when yvars is null, statistical tests are made on xvars.
alter	could be two.sided,less,greater.
paired	logical, if the x variable and yvariable is paired.
confLevel	confidence level,alpha=1-confLevel
nullHyp	eg. mu=0 in t.test
normalSampleSize	integer, when sample size exceed this value, always using parametric tests instead.

Details

when there are multiple variables both in xvars and yvars params, hTest performs statistical tests on each x and y.

Examples

hTest(iris,xvars=c('Sepal.Length','Sepal.Width'),yvars='Species',alter='two.sided')->res
res$hTestRes

plot(res$hTestGraph)
