Answer 1

Here is a my solution to this:

resize.win <- function(Width=6, Height=6)
{
        # works for windows
    dev.off(); # dev.new(width=6, height=6)
    windows(record=TRUE, width=Width, height=Height)
}
resize.win(5,5)
plot(rnorm(100))
resize.win(10,10)
plot(rnorm(100))

Answer 2

Some workaround could be rather than using dev.new() R function use this function which should work across platform :

 dev.new <- function(width = 7, height = 7) 
 { platform <- sessionInfo()$platform if (grepl("linux",platform)) 
 { x11(width=width, height=height) } 
 else if (grepl("pc",platform)) 
 { windows(width=width, height=height) } 
 else if (grepl("apple", platform)) 
 { quartz(width=width, height=height) } }
