ggplot2 is based on the grammar of graphics the idea that you can build every graph from the same components: a data set a coordinate system and geoms—visual marks that represent data points Basics GRAPHICAL PRIMITIVES a + geom_blank() (Useful for expanding limits)

coordinate system plot Complete the template below to build a graph required ggplot(data = mpg aes(x = cty y = hwy)) Begins a plot that you finish by adding layers to Add one geom function per layer qplot(x = cty y = hwy data = mpg geom = “point") Creates a complete plot with given data geom and mappings
ggplot2 geoms with support for pattern ?lls Description All geoms in this package are identical to their counterparts in ggplot2 except that they can be ?lledwith patterns Usage geom_rect_pattern( mapping = NULL data = NULL stat = "identity" position = "identity" linejoin = "mitre" na rm = FALSE show legend = NA inherit aes = TRUE
ggplot(df aes(variable))instead of ggplot(df aes(df$variable))) The names for x and y aesthetics are typically omitted because they are so common; all other aesthetics must be named Details This function also standardises aesthetic names by converting color to colour (also in substrings
