Preserving plot dimensions from one plot to another in R

[garchbrooks]

I saw some people here post some good advice about using R once, so I started to teach myself how to use it.

There's a command called par(new=T) that lets you plot over the previous plot. The problem is that even though you're using the same plot, the dimensions of a new plot can change. I was wondering if there was some way to take a "snapshot" of the dimensions from one plot and then preserve them for use with another plot.

Does anyone know how to do this?

Using lines() and points() helped me achieve what I wanted to achieve, but I'd be interested in a solution involving par(new=T) if anyone out there has such a solution.

you could assign your par params to a variable like

orig<- par(mfrow = c(5,1) )


and then use that next time like

par(orig)

theres also library ggplot2 thats supposed to be popular
