Longer answer: (copied from the ggplot2 home page) "ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and none of the bad parts. A variation on geom_text() is geom_label(): it draws a rounded rectangle behind the text. This makes it useful for adding labels to plots with busy backgrounds: Labelling data well poses some challenges: Text does not affect the limits of the plot. multiply by 25.4 / 72.27). 3) Example 2: Show Number in Scientific Notation with Only Two Digits. Setting labs(x = "") omits the label but still allocates space; setting labs(x = NULL) removes the label and its space. r Share Scientific notation in R | DataKwery density matrix. In this tutorial youll learn how to modify the formatting of axis values in a ggplot2 graph in R programming. The second variable specifies the "columns" of the small multiple grid. to write the expression using Markdown or HTML syntax. side for continuous variables and by 0.6 units on each side for discrete e+06 instead of e+07).
