add title using grid.arrange for multiple plots made with gridExtra::grid.arrange

I have to use gridExtra::grid.arrange for plotting several plot besides eachother because of the package I am using to create the fit for the plot. I have to create a title for the plot using grid.arrange. Now I want to combine the two, but cannot figure out how. So: I want to plot several figures besides eachother and give them all have a different title.

I have euler1 and euler2 as fits tat represent my data in an euler diagram. for plotting 2 plots besides eachother this code works for me: 

gridExtra::grid.arrange(plot(euler1),plot(euler2))

for giving a single plot a title, this code works for me:

plot1 <- plot(euler1)
grid.arrange(grobs = list(plot1), top = "Title 1")

Now, I would like to combine the two codes. How can I do it?

I tries for example (but doesn't work):

plot1 <- plot(euler1)
plot2 <- plot(euler2)
gridExtra::grid.arrange(plot1, plot2, grobs = list(plot1, plot2), top = list("Title 1","Title 2"))

Kinds regards, Judith

I figured out how to do it, since the use of main in plot was fixed for the eulerr package. Now I can use:

gridExtra::grid.arrange(plot(euler1, main = 'title1'),
plot(euler2, main = 'title2'))

Thanks everyone for the feedback.

Typically you'd add titles to the plot themselves, as in

p1 = ggplot() + ggtitle('plot 1')
p2 = ggplot() + ggtitle('plot 2')

grid.arrange(grobs = list(p1, p2), top = "Global Title", ncol=2)

but if you prefer to use grid.arrange's top argument for the titles, you can nest them,

p = ggplot()
grid.arrange(arrangeGrob(p, top = 'title 1'), arrangeGrob(p, top = 'title 2'), top = "Global Title", ncol=2)
