show ggplot r code example

Example: ggplots in r

library(ggplot2)
ggplot(diamonds)  # if only the dataset is known.
ggplot(diamonds, aes(x=carat))  # if only X-axis is known. The Y-axis can be specified in respective geoms.
ggplot(diamonds, aes(x=carat, y=price))  # if both X and Y axes are fixed for all layers.
ggplot(diamonds, aes(x=carat, color=cut))  # Each category of the 'cut' variable will now have a distinct  color, once a geom is added.
