how to adjust plot area size

[Herbert Jägle]

I am creating multiple plots which are adjusted with grid.arrange. An
example is given below.
The plot area size depends on the size of the axis labels so two plots
in a column are not adjusted.

Is it possible to set fixed size or adjust the size of the plot area?

Thanks,
Herbert

--------------------
df.d <- data.frame(x=c(1:10), y1=c(1:10)/10, y2=c(1:10)*10000)

label=y_label_formatter <- function(x) {lab <- sprintf('%5.0f', x)}

q <- ggplot(df.d) +
geom_point(aes(x, y1)) +
scale_x_continuous(name='x-axis', limits=c(0, 11)) +
scale_y_continuous(name='y1-axis', limits=c(0, 1.1),
label=y_label_formatter)

r <- ggplot(df.d) +
geom_point(aes(x, y2)) +
scale_x_continuous(name='', limits=c(0, 11)) +
scale_y_continuous(name='y2-axis', limits=c(0, 110000),
label=y_label_formatter)

theme_set(theme_bw())
plots.l <- list(ggplotGrob(r), ggplotGrob(q))
args.l <- c(plots.l, nrow=2, ncol=1)
do.call(grid.arrange, args.l)

You could try the following function set_panel_size() which adjusts
the gtable size,
