Make the Gabriel's barplot, if, and only if, their bar intervals are disjoint, they are differ significantly. This function could also be used to plot error bar when the bar vector is imported as upper or lower margin.

Usage

gabriel.plot(x, f, upper, lower = upper, length = 0.1, ...)

Arguments

x

data vector

f

factor vector

upper

the upper margin of error bar

lower

length

the length of error bar

...

Arguments to be passed to methods, such as graphical parameters.
