Description

Errorbars to be used with base plotting

Usage

errorbars(x, Mean, SE, col, lty = 1, length = 0.07, lwd = 1)

Arguments

x

x value

Mean

mean value or y alternative

SE

standard error

col

color of bars

lty

Line type The line type. Line types can either be specified as an integer (0=blank, 1=solid (default), 2=dashed, 3=dotted, 4=dotdash, 5=longdash, 6=twodash) or as one of the character strings "blank", "solid", "dashed", "dotted", "dotdash", "longdash", or "twodash", where "blank" uses ‘invisible lines’ (i.e., does not draw them).

length

length of the edges of the error bar head (in inches).

lwd

line width

Value

draws lines in the form of error bars

Note

see arrows() function

Examples

x.val=c(1,2,3)
mean.val=c(2,5,7)
se.val=c(0.1,0.5,1)
plot(mean.val~x.val,ylim=c(0,10))
errorbars(x.val,mean.val,se.val,"red")
