Description

A wrapper function for the aov function, which performs a standard ANOVA.

Usage

basicAnova(Data, Treatment, Response, WeightList)

Arguments

Data	A data set.
Treatment	The name (as a string) of the treatment variable.
Response	The name (as a string) of the response variable.
WeightList	The name (as a string) of the variables containing the weight for ANOVA. Set this value to NULL to indicate that weights are not being used.

Sum Sq	The within treatment sum of squares.
Df	The degrees of freedom.
F value	The value of the F-statistic.
Pr(>F)	The p-value corresponding to the F statistic.
Signif	The significance flag for the where "." is a p-value > 0.05, "*" is a 0.01 < p-value <= 0.05, "**" for 0.001 < p-value <= 0.01, and "***" for p-value <= 0.001.
