Using mtext() you can do something like the following:


# Now place labels closer to the x axis
# set 'axisnames' to FALSE so the default
# labels are not drawn. Also note that barplot() 
# returns the bar midpoints, so set 'mp' to the return
# values
mp <- barplot(VADeaths, axisnames = FALSE)

# Now use mtext() for the axis labels
mtext(text = colnames(VADeaths), side = 1, at = mp, line = 0)

# clean up

You can adjust the 'line = 0' argument to move the labels closer to and
farther away from the axis.
