position_nudge is generally useful for adjusting the position of items on discrete scales by a small amount. Nudging is built in to geom_text() because it's so useful for moving labels a small distance from what they're labelling.

position_nudge(x = 0, y = 0)

Arguments

x, y

Amount of vertical and horizontal distance to move.

Examples

df <- data.frame( x = c(1,3,2,5), y = c("a","c","d","c") ) ggplot(df, aes(x, y)) + geom_point() + geom_text(aes(label = y))
ggplot(df, aes(x, y)) + geom_point() + geom_text(aes(label = y), position = position_nudge(y = -0.1))
# Or, in brief ggplot(df, aes(x, y)) + geom_point() + geom_text(aes(label = y), nudge_y = -0.1)
