Response:

Correct answer is Option b – bwplot()

Bwplot() is the Box and Whisker plot used for numerical VARIABLES. This is part of lattice PACKAGE in R.

Below is an example of a box and whisker plot using the singer dataset.

library(lattice)

require(stats)

#bwplot bwplot(voice.part ~ height, DATA=singer, xlab="Height (inches)") plot() is used for generic x-y plotting. xyplot() PRODUCES bivariate scatterplots or time-series plots. #xyplot ## Tonga Trench Earthquakes Depth <- equal.count(quakes$depth, number=8, overlap=.1) xyplot(lat ~ LONG | Depth, data = quakes)

dotplot() produces Cleveland dot plots.
