One-way Analysis of Variance Plot

Description

Displays stripplot/boxplot of the reponse variable with intervals by factor levels. It is used as part of a one-way anova analysis.

Usage

onewayPlot(x,...)
## S3 method for class 'formula':
onewayPlot(formula, data = parent.frame(),
                             conf.level = 0.95,
                             interval.type = "tukey",
                             pooled = TRUE, strip = TRUE, vert = TRUE,
                             verbose = FALSE,
                             ylabel = deparse(terms(formula)[[2]]),
                             flabel = deparse(terms(formula)[[3]]),...)
## S3 method for class 'lm':
onewayPlot(x,...)

Arguments

formula a symbolic description of the model to be fit.
x either a formula or a lm object
conf.level confidence level of the intervals.
interval.type three options for intervals appearing on plot: "hsd","lsd" or "ci".
pooled two options: pooled or unpooled standard deviation used for plotted intervals.
strip if strip=F, boxplots are displayed instead.
vert if vert=F, horizontal stripplots are displayed instead (boxplots can only be displayed vertically).
verbose if true, print intervals on console.
ylabel can be used to replace variable name of y by another string.
flabel can be used to replace variable name of f by another string.
data an optional data frame in which to evaluate the formula.
... optional arguments.
