ErrorBarPlotPanel function

Plots a panel of error bars

Plots a panel of error bars to compare the means of several variables in the levels of a factor using confidence intervals.

ErrorBarPlotPanel(X, groups = NULL, nrows = NULL, panel = TRUE, 
GroupsTogether = TRUE, Confidence = 0.95, p.adjust.method = "None", 
UseANOVA = FALSE, Colors = "blue", Title = "Error Bar Plot", 
sort = TRUE, ...)

Arguments

• X: A matrix containing several variables
• groups: A factor defining groups of individuals
• nrows: Number of rows of the panel. The function calculates the number of columns needed.
• panel: The plots are shown on a panel (TRUE) or in separated graphs (FALSE)
• GroupsTogether: The groups appear together on the same plot
• Confidence: Confidence levels for the error bars (confidence intervals)
• p.adjust.method: Method for adjusting the p-value to cope with multiple comparisons.
• UseANOVA: If TRUE the function uses the residual variance of the ANOVA to calculate the confidence interval. ("None", "Bonferroni" or "Sidak")
• Colors: Colors to identyfy the groups
• Title: Title of the graph
• sort: Should short the means before plotting
• ...: Other graphical parameters

Details

The funtion plots a panel of error bars plots to compare several groups for several variables.

Returns
