Answer 1

You may try to play around with the width of the device you plotting to. E.g.:

# plot to a Windows graphic device
windows(height = 10, width = 4)
barplot(0.5)

# plot to PDF
pdf(height = 10, width = 2)
barplot(0.5)
dev.off()

You may also try width together with xlim

barplot(0.5, width = 0.1, xlim = c(0, 1))
