errorbarplot: barplot with errorbars
In drmjc/mjcgraphics: mjc's graphics library

'height' and 'errors' much match exactly in dimension, and can either be both vectors, or both matrices.

  errorbarplot(height, width = 1, space = NULL,
    beside = FALSE, horiz = FALSE, ylim = NULL,
    xlim = NULL, ..., errors = NULL,
    errors.col = par("fg"), errors.width = 0.15,
    errors.type = c("+", "-"), pvalue.stars = NULL,
    pvalue.stars.pos = c("none", "above", "below", "top", "bottom", "left", "right"),
    pvalue.stars.cex = 1, pvalue.stars.col = "black",
    pvalue.stars.space = 0.05)

`height`	see `barplot`
`width`	see `barplot`
`space`	see `barplot`
`beside`	see `barplot`
`horiz`	see `barplot`
`ylim`	see `barplot`
`xlim`	see `barplot`
`...`	see `barplot`
`errors`	the object containing errors (eg standard deviation) with the SAME size and dimension as `height`.
`errors.col`	the colour of the errors bars
`errors.width`	the proportion of width that the ticks should be at the top/bottom or lhs/rhs of the error tick
`errors.type`	plot the errors bars going into and outof the bar itself (eg just "+" will plot the tick pointing out of the bar)
`pvalue.stars`	stars to add above significant bars, or `NULL`. must be same dimensions as `height` and `errors`
`pvalue.stars.pos`	where to put the stars? one of above, top, right, below, bottom, left
`pvalue.stars.cex`	size of the stars
`pvalue.stars.col`	colour of the stars
`pvalue.stars.space`	buffer between stars and the errorbar
