aes() arguments: x, ymax, ymin, alpha, color, fill, group, linetype, size.Ĭommon aesthetics: x, y, alpha, color, linetype, size, linewidth.ī + geom_abline(aes(intercept = 0, slope = 1)): Draw a diagonal reference line with a given slope and intercept.ī + geom_hline(aes(yintercept = lat)): Draw a horizontal reference line with a given yintercept.ī + geom_vline(aes(xintercept = long)): Draw a vertical reference line with a given xintercept.ī + geom_segment(aes(yend = lat + 1, xend = long + 1)): Draw a straight line from (x, y) to (xend, yend).ī + geom_spoke(aes(angle = 1:1155, radius = 1)): Draw line segments using polar coordinates ( angle and radius).

aes() arguments: xmax, xmin, ymax, ymin, alpha, color, fill, linetype, size.Ī + geom_ribbon(aes(ymin = unemploy - 900, ymax = unemploy + 900): For each x, plot an interval from ymin to ymax. aes() arguments: x, y, alpha, color, fill, group, subgroup, linetype, size.ī + geom_rect(aes(xmin = long, ymin = lat, xmax = long + 1, ymax = lat + 1)): Draw a rectangle by connecting four corners ( xmin, xmax, ymin, ymax). aes() arguments: x, y, alpha, color, group, linetype, size.Ī + geom_polygon(aes(alpha = 50)): Connect points into polygons. aes() arguments: x, xend, y, yend, alpha, angle, color, curvature, linetype, size.Ī + geom_path(lineend = 'butt', linejoin = 'round', linemitre = 1): Connect observations in the order they appear. Graphical PrimitivesĪ <- ggplot(economics, aes(date, unemploy)) b <- ggplot(seals, aes( x = long, y = lat))Ī + geom_blank() and a + expand_limits(): Ensure limits include values across all plots.ī + geom_curve(aes(yend = lat + 1, xend = long + 1), curvature = 1): Draw a curved line from (x, y) to (xend, yend). Use a geom function to represent data points, use the geom’s aesthetic properties to represent variables.

shape integer/name pairs: 0 = 'square open', 1 = 'circle open', 2 = 'triangle open', 3 = 'plus', 4 = 'cross', 5 = 'diamond open', 6 = 'triangle down open', 7 = 'square cross', 8 = 'asterisk', 9 = 'diamond plus', 10 = 'circle plus', 11 = 'star', 12 = 'square plus', 13 = 'circle cross', 14 = 'square triangle', 15 = 'square', 16 = 'circle', 17 = 'triangle', 18 = 'diamond', 19 = 'circle small', 20 = 'bullet', 21 = 'circle filled', 22 = 'square filled', 23 = 'diamond filled', 24 = 'triangle filled', 25 = 'triangle down filled'.

Shape: Integer/shape name or a single character ( 'a'). Linewidth: Integer (line width in mm for lines).

Size: Integer (line width in mm for outlines). Linetype: Integer or string (0 = 'blank', 1 = 'solid', 2 = 'dashed', 3 = 'dotted', 4 = 'dotdash', 5 = 'longdash', 6 = 'twodash'). Matches file type to file extension.Ĭolor and fill: String ( 'red', '#RRGGBB'). Ggsave('plot.png', width = 5, height = 5): Saves last plot as 5’ x 5’ file named “plot.png” in working directory. Ggplot(data = mpg, aes(x = cty, y = hwy)): Begins a plot that you finish by adding layers to. Stat, Position, and the Coordinate, Facet, Scale, and Theme functions are not required and will supply sensible defaults. ggplot(data = ) +ĭata, a Geom Function, and Aes Mappings are required.
