r - Increase plot size (width) in ggplot2

Question

Below is a plot that I want to include in a paper. The problem is the width of my plot which is to small (that make x-axix not readable at all)

Here is the ggplot2 code myCode.r :

require("ggplot2")

all <- read.csv(file="benchmark/bench.query.csv", head=TRUE, sep=";")

w <- subset(all, query %in% c("sort.q1", "sort.q2", "sort.q3", "sort.q4", "sort.q5"))

w$rtime <- as.numeric(sub(",", ".", w$rtime, fixed=TRUE))

p <- ggplot(data=w, aes(x=query, y=rtime, colour=triplestore, shape=triplestore))
p <- p + scale_shape_manual(values = 0:length(unique(w$triplestore)))
p <- p + geom_point(size=4)
p <- p + geom_line(size=1,aes(group=triplestore))
p <- p + labs(x = "Requêtes", y = "Temps d'exécution (log10(ms))")
p <- p + scale_fill_continuous(guide = guide_legend(title = NULL))
p <- p + facet_grid(trace~type)
p <- p + theme_bw()

ggsave(file="bench_query_sort.pdf")

print (p)

I've look around to see how to enlarge the plot, but I found nothing.

Any idea about what to add/delete/modify in my code ?

Inside a Jupyter notebook I found the following helpful:

# Make plots wider 
options(repr.plot.width=15, repr.plot.height=8)
