Modify axis, legend, and plot labels using ggplot2 in R By default, R will use the variables provided in the Data Frame as the labels of the axis. We can modify them and change their appearance easily. The functions which are used to change axis labels are : xlab ( ) : For the horizontal axis. ylab ( ) : For the vertical axis. labs ( ) : For both the axes simultaneously. 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.

Change Labels of ggplot2 Facet Plot in R | Modify & Replace Names The following code illustrates how to replace facet labels of a ggplot2 graph by changing the factor levels of our grouping column.

Beautiful dendrogram visualizations in R: 5+ must known methods ... - STHDA x: an object of the type produced by hclust(); labels: A character vector of labels for the leaves of the tree.The default value is row names. if labels = FALSE, no labels are drawn.; hang: The fraction of the plot height by which labels should hang below the rest of the plot.A negative value will cause the labels to hang down from 0. main, sub, xlab, ylab: character strings for title. 8.8 Changing the Text of Tick Labels - R Graphics To set arbitrary labels, as in Figure 8.15 (right), pass values to breaks and labels in the scale. One of the labels has a newline ( \n) character, which tells ggplot to put a line break there: hw_plot + scale_y_continuous( breaks = c(50, 56, 60, 66, 72), labels = c("Tiny", "Really\nshort", "Short", "Medium", "Tallish") ) How to customize Bar Plot labels in R - How To in R Customize Axis Labels The font, color, and orientation of the axis labels can be customized per the font.axis, col.axis, and las arguments. barplot (ElementContainingData, font.axis = FontValue, col.axis = "Color", las = OrientationValue ) Font Values: Normal Bold Italic Bold Italic Orientation Value: 0. Y = Vertical, X = Horizontal 1. Quick-R: Value Labels To understand value labels in R, you need to understand the data structure factor. You can use the factor function to create your own value labels. # variable v1 is coded 1, 2 or 3 # we want to attach value labels 1=red, 2=blue, 3=green mydata$v1 <- factor (mydata$v1, levels = c (1,2,3), labels = c ("red", "blue", "green"))
