ggPlot2: Basics
Basic Plot |
ggplot(dataset, aes(x, y, colour=z) |
ggPlot2: layers
mapping |
Some asthetic mappings (aes) |
data |
The dataset to use |
geom |
Override default geom |
stat |
Override default stat |
position |
Adjustment for overlapping objects (dodge, fill, identity, jitter, stack) |
... |
Parameters for geom or stat; also aesthetics with constant values |
Layers may be added to plot objects using the layer command or stat_... and geom_... functions. Parameters not set are taken from the function's or plot's default values.
