The use for par is: > plot(1:8,1:8) #you must have an open graphics window before par has an effect > par(mar=c(5,4,4,2)) #this will stay in effect until you either close the graphics window or change it with another call to par > plot(1:8,1:8)
In other words, par works on an open graphics device and applies to all subsequent plots to that device. You can't put it in the plot command--a bit awkward at times, but often does save time and is very general.
