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, ...)
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 |
