Their settings can be changed with theme()Įxample how to change background color to white.Theme settings can be accessed with theme_get().Effects are global when passed on to ggplot() and local for other components. aes() mappings can be passed on to all components ( ggplot, geom, etc.).aesthetic mappings provided by aes function.

More important than qplot to access full functionality of ggplot2. Local regression curve (loess) p <- qplot ( carat, price, data = dsmall, geom = c ( "point", "smooth" )) print ( p ) # Setting se = FALSE removes error shade Regression line set.seed ( 1410 ) dsmall <- diamonds p <- qplot ( carat, price, data = dsmall ) + geom_smooth ( method = "lm" ) print ( p ) Plot different shapes qplot ( x, y, geom = "point", size = 5, shape = cat )Ĭolored groups p <- qplot ( x, y, geom = "point", size = x, color = cat, main = "Dot Size and Color Relative to Some Values" ) + theme ( legend.position = "none" ) print ( p ) Prints dots with different sizes and colors qplot ( x, y, geom = "point", size = x, color = cat, main = "Dot Size and Color Relative to Some Values" )ĭrops legend qplot ( x, y, geom = "point", size = x, color = cat ) + theme ( legend.position = "none" ) Simple scatter plot qplot ( x, y, geom = "point" ) : many arguments accepted by plot functionĬreate sample data library ( ggplot2 ) x <- sample ( 1 : 10, 10 ) y <- sample ( 1 : 10, 10 ) cat <- rep ( c ( "A", "B" ), 5 ) xlab, ylab: labels for the x- and y-axes. main: main title see ?plotmath for mathematical formula. data: data frame with corresponding column names. The syntax of qplot is similar as R’s basic plot function Packages with convenience utilities to create expected inputs. qplot: ame (support for vector, matrix. Settings of plotting theme can be accessed with the command theme_get() and its settings can be changed with theme(). List of available geom_* functions see here.
