datautils (version 0.1.5)

plotmeanshack:

Description

Hack of the plotmeans function (gplots package), to allow native scale on the x axis, if the associated grouping variable is numeric.

Usage

plotmeanshack(formula, data = NULL, subset, na.action, bars = TRUE, 
    p = 0.95, minsd = 0, minbar = NULL, maxbar = NULL, xlab = names(mf)[2], 
    ylab = names(mf)[1], mean.labels = FALSE, ci.label = FALSE, 
    n.label = TRUE, digits = getOption("digits"), col = "black", 
    barwidth = 1, barcol = "blue", connect = TRUE, ccol = col, 
    legends = names(means), xaxt, use.t = TRUE, nummeans=TRUE, ...)

names(irisdat)[5] <- "iris.class"
plotmeanshack(Sepal.Width ~ iris.class, data=irisdat, nummeans=TRUE) # (artificial) numeric variable
