Hi R users,
I find par("pin") is kind of confusing (or maybe just me?). The manual said
it will give " The current plot dimensions, (width,height), in inches."
The word "current" is the key here. I thought it would give the dimensions
of the to-be plot, but it actually gives the dimension of the finished plot:
> layout(matrix(c(1,2,3,4), nrow=2), width=c(1,3), height=c(1,3))
> par("pin")
[1] 4.216666 3.721324
> plot(x)
> par("pin")
[1] 0.7194221 0.2223079
> plot(x)
> par("pin")
[1] 0.7194221 3.7213237
> plot(x)
> par("pin")
[1] 4.2166662 0.2223079
> plot(x)
So, if par("pin") doesn't give to-be plot, how can I get its dimension?
Thanks,
Zech
