errorBars: errorBars

In bobverity/bobFunctions: my personal functions

Description

Produce error bars at given positions. When se=FALSE, input should be y1=lower limit and y2=upper limit. When se=TRUE, input should be y1=mean and y2=standard error, in which case error bars represent two standard errors either side of the mean. Can handle vector inputs as well as scalars.

Usage

errorBars(y1, y2, x = 1:length(y1), se = FALSE, width = 1, col = 1,
  lty = 1, lwd = 1)

Arguments

y1	under first method (when se=FALSE) this value is the lower limit of the error bar. Under the second method (when se=TRUE) this value is the mean of the distribution that will be used to produce error bars (mean +- 1.96 standard deviations).
y2	as above, either the upper limit of the error bar, or the standard deviation of the distribution that will be used to produce error bars.
x	horizontal position of error bars.
se	whether to use values y1 and y2 as mean and standard deviation.
width	length of error bar handles.
col	colour of error bars.
lty	line type of error bars.
lwd	line width of error bars.
