R - Changing ggplot plot size in jupyter

Using R in a jupyter notebook, first I set the plot size universally. Second, I would like to plot one single plot with a different size.

## load ggplot2 library
library("ggplot2")
## set universal plot size:
options(repr.plot.width=6, repr.plot.height=4)

## plot figure. This figure will be 6 X 4
ggplot(iris, aes(x = Sepal.Length, y= Sepal.Width))   +  geom_point() 

## plot another figure. This figure I would like to be 10X8
ggplot(iris, aes(x = Sepal.Length, y= Sepal.Width))   +  geom_point() + HOW DO i CHANGE THE SIZE?

As you can see, I would like to change the second plot (and only the second plot) to be a 10X8. How do I do this?

Sorry for a potentially dumb question, as plot sizing is typically not an issue in Rstudio.

I've found another solution which allows to set plot size even when you make plots inside function or a loop:

pl <- ggplot(iris, aes(x = Sepal.Length, y= Sepal.Width)) + geom_point()
print(pl, vp=grid::viewport(width=unit(10, 'inch'), height=unit(8, 'inch')))

If options is the only mechanism available to change figure size, then you'd do something like this to set & restore the options to whatever they were:

saved <- options(repr.plot.width=10, repr.plot.height=8)
ggplot(iris, aes(x = Sepal.Length, y= Sepal.Width)) + geom_point()
options(saved)

A solution that doesn't involve using external packages is this.

fig <- function(width, heigth){
 options(repr.plot.width = width, repr.plot.height = heigth)
 }

Just put fig(10, 4), for example, in the cell that generates the plot, and the plot will be scaled accordingly
