string - R ggplot2 Add today's date to the title

In principle, I'm sure this is straightforward....

How do I append today's date to my ggplot title?

today.date <- Sys.Date() 
labs(title='Daily New COVID-19 Hospitalizations as of ', x=....)

In other words, what's the R / ggplot syntax to append today.date to my plot title? Am I better off using ggtitle rather than labs for the title -- does that make it easier?

Thank you!

Both with labs and ggtitle you can use function paste() as follows:

labs(title = paste('Daily New COVID-19 Hospitalizations as of', today.date, sep = " "))

or

ggtitle(paste('Daily New COVID-19 Hospitalizations as of', today.date, sep = " "))
