pt_error(
  x,
  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

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)
