Line types in R

The function used to generate this figure is provided at the end of this document.

line type (lty) can be specified using either text (“blank”, “solid”, “dashed”, “dotted”, “dotdash”, “longdash”, “twodash”) or number (0, 1, 2, 3, 4, 5, 6). Note that lty = “solid” is identical to lty=1.

Examples

# Solid line (by default)
plot(1:10, 1:10, type="l")
# Use dashed line type
plot(1:10, 1:10, type="l", lty=2)
# Change line width
plot(1:10, 1:10, type="l", lty=2, lwd=3)

plot of chunk example

By default lty = 1

R script to generate a plot of line types

Use the following R function to display a graph of the line types available in R :

#Line types
#++++++++++++++++++++++++++++++++++++++++++++
generateRLineTypes<-function(){
  oldPar<-par()
  par(font=2, mar=c(0,0,0,0))
  plot(1, pch="", ylim=c(0,6), xlim=c(0,0.7),  axes=FALSE,xlab="", ylab="")
  for(i in 0:6) lines(c(0.3,0.7), c(i,i), lty=i, lwd=3)
  text(rep(0.1,6), 0:6, labels=c("0.'blank'", "1.'solid'", "2.'dashed'", "3.'dotted'",
                                 "4.'dotdash'", "5.'longdash'", "6.'twodash'"))
  par(mar=oldPar$mar,font=oldPar$font )
}
generateRLineTypes()
