You don't want a histogram, but a barplot:

x <- c(0.0001, 0.0059, 0.0855, 0.9082)

y <- c(0.54, 0.813, 0.379, 0.35)

# create a two row matrix with x and y

height <- rbind(x, y)

# Use height and set 'beside = TRUE' to get pairs # save the bar midpoints in 'mp' # Set the bar pair labels to A:D mp <- barplot(height, beside = TRUE, ylim = c(0, 1), names.arg = LETTERS[1:4])

# Draw the bar values above the bars

text(mp, height, labels = format(height, 4), pos = 3, cex = .75)

See ?barplot, ?text and ?format (or ?formatC or ?sprintf).

**HTH,
