plot.err: Plot means and error bars

In gtimmerhaus/aquaR: Functions for aquaculture related topics

Description

Plot the mean of a data vector, grouped be the group vector and add error bars.

Usage

## S3 method for class 'err'
plot(data, groups, at = FALSE, type = "dot", barwidth = 0.2,
  col = "black", err.bars = "sterr", cex = 2, xlab = "",
  ylab = "means", length = 0.1, lwd = 1, main = "", las.x = 1,
  las.y = 2, xaxt = T, cex.yaxis = 1, cex.xaxis = 1, yscale = c(1, 1),
  stats = T, stats.mark = T, sig.groups = F)

Arguments

data	a numeric vector containing the data to plot.
groups	vector containing the group information for data.
at	optinal vector to arrange the position of the data points on the x-axis.
type	type of plot: Either "dot" for dots, "bar" for bars or "diffbar" for bars, starting at the average.
barwidth	if type="bar", barwidth defines the width of the bars.
col	vector defining the color for each group. Must have the same length as number of groups.
err.bars	error bars show standard error ("sterr") or standard deviation ("sd").
cex	defines the size of the dots.
xlab	label for x-axis.
ylab	label for y-axis.
length	defines the length of the arrow heads of the error bars
lwd	line width of the error bars.
main	title of the plot
las.x	text orientation of the x-axis labels.
las.y	text orientation of the y-axis labels.
xaxt	add x-axis if TRUE
cex.yaxis	scaling for y-axis labels
cex.xaxis	scaling for x-axis labels
yscale	vector of length two to scale the ylim's upper and lower limit
stats	add ANOVA results to the plot
stats.mark	add stars to significant ANOVA results
sig.groups	vector with significant marker, which will be places over the error bars (order is 1:n and not according to at!)

Examples

plot.err(hr.data$weight, hr.data$group)
plot.err(hr.data$weight, paste(hr.data$group, hr.data$rank))
