dotplots.errors, a new R function to ease the pain of creating dotplots

Dot plots are preferred over barplots to present estimates with error bars for grouped data, yet the latter are overwhelmingly more often used in such situations. The paper presents a code for an R function to produce a dot plot with error bars, employing the utility of the lattice package. Easy to use for non-advanced users of lattice and R, it offers much possibilities to control
