Errorbars to be used with base plotting

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")
