  y,
  SE,
  pch,
  bg,
  ln.col,
  ln.lwd,
  cex = 1,
  pt.lwd = 0.5,
  pt.lty = 1,
  pt.col = "black",
  length = 0.07
)

Arguments

x: x-value
y: y-value (or mean)
SE: standard error
pch: plotting ‘character’, i.e., symbol to use. see points()
bg: background (fill) color for the open plot symbols given by pch = 21:25. see points()
ln.col: color of error bar lines
ln.lwd: width of error bar lines
cex: size of point
pt.lwd: line width of points
pt.lty: line type for points
pt.col: color of point
length: length of the edges of the error bar head (in inches).

Value

draws lines in the form of error bars

Note

see arrows() and errorbars() functions

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),type="n")
pt_error(x.val,mean.val,se.val,21,"dodgerblue1","grey",2,cex=2)
