How to Label Points on a Scatterplot in R (With Examples) - Statology This tutorial provides an example of how to label the points on a scatterplot in both base R and ggplot2. Example 1: Label Scatterplot Points in Base R. To add labels to scatterplot points in base R you can use the text() function, which uses the following syntax: text(x, y, labels, …) x: The x-coordinate of the labels; y: The y-coordinate of the labels Annotating select points on an X-Y plot using ggplot2 WARcht = ggplot (outfield, aes (x=UZR.150, y=wRAA)) + #. geom_point (colour="gray60″, size=2.0) + # set the colour and size of the points. theme_bw () + # and use the "background white" theme. ggtitle ("Everyday Outfielders, 2013 [to 2013-06-15]") # and put a title on the plot. #.

Text — geom_label • ggplot2 geom_text() and geom_label() add labels for each row in the data, even if coordinates x, y are set to single values in the call to geom_label() or geom_text(). To add labels at specified points use annotate() with annotate(geom = "text", ...) or annotate(geom = "label", ...). To automatically position non-overlapping text labels see the ggrepel package.

Stats An alternative way to build a layer. + = data geom x = x · Adding Labels to a {ggplot2} Bar Chart - thomasadventure.blog To add an annotation to the bars you'll have to use either geom_text() or geom_label().I will start off with the former. Both require the label aesthetic which tells ggplot2 which text to actually display. In addition, both functions require the x and y aesthetics but these are already set when using bar_chart() so I won't bother setting them explicitly after this first example. GGPlot Axis Labels: Improve Your Graphs in 2 Minutes - Datanovia This article describes how to change ggplot axis labels (or axis title ). This can be done easily using the R function labs () or the functions xlab () and ylab (). Remove the x and y axis labels to create a graph with no axis labels. For example to hide x axis labels, use this R code: p + theme (axis.title.x = element_blank ()).

Ggplot label specific points. Modify ggplot X Axis Tick Labels in R | Delft Stack In this case, we utilize scale_x_discrete to modify x axis tick labels for ggplot objects. Notice that the first ggplot object is a bar graph based on the diamonds data set.
