[BioC] Changing margins on a boxplot

[Jarno Tuimala]

Hi!

You can set margins to boxplot (or any plot for that matter) by first setting 
the graphical parameters, e.g.:

par(mar=c(0,0,0,0))     # Removes margins
par(mar=c(5,4,4,2)+0.1) # Default
par(mar=c(8,8,4,2))     # Larger bottom and left margins

and then calling the boxplot function:

boxplot(rnorm(100))

You can do this using the pars -argument in the boxplot command, also, e.g.:

boxplot(n, pars=list(par(mar=c(0,0,0,0))))
