39 ggplot2 label points

Text — geom_label • ggplot2 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. Aesthetics geom_text () understands the following aesthetics (required aesthetics are in bold): x y label alpha angle colour family fontface group 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

8 Annotations | ggplot2 The ggplot2 package doesn't have all the answers, but it does provide some tools to make your life a little easier. The main tool for labelling plots is geom_text (), which adds label text at the specified x and y positions. geom_text () has the most aesthetics of any geom, because there are so many ways to control the appearance of a text:

If you use a line graph, you will probably need to use scale_colour_xxx and/or scale_shape_xxx instead of scale_fill_xxx.colour maps to the colors of lines and points, while fill maps to the color of area fills.shape maps to the shapes of points.

Ggplot2 label points. r - label specific point in ggplot2 - Stack Overflow Your current plot should look like this (point + labels): ggplot (data=df,aes (x=A,y=B,label=genes)) + geom_point () + geom_text (hjust=-1,vjust=1) In order to highlight some genes, we create a new variable, group. I assign "important" to some arbitrary genes. You may want to do this programatically, by looking for outliers for instance. r - Label points in geom_point - Stack Overflow ggplot (nba, aes (x= MIN, y= PTS, colour="green", label=Name))+ geom_point () +geom_text (hjust=0, vjust=0) EDIT: Label only values above a certain threshold: ggplot (nba, aes (x= MIN, y= PTS, colour="green", label=Name))+ geom_point () + geom_text (aes (label=ifelse (PTS>24,as.character (Name),'')),hjust=0,vjust=0) Share Improve this answer Add text labels to a ggplot2 plot — LabelPoints • Seurat - Satija Lab Arguments plot.

A vector of labels for the points; if NULL, will use rownames of the data provided to the plot at the points selected. repel. Use geom_text_repel to create a nicely-repelled labels; this is slow when a lot of points are being plotted. Modify axis, legend, and plot labels — labs • ggplot2 Modify axis, legend, and plot labels — labs • ggplot2 Modify axis, legend, and plot labels Source: R/labels.r Good labels are critical for making your plots accessible to a wider audience. Always ensure the axis and legend labels display the full variable name. Use the plot title and subtitle to explain the main findings.

How to Add Labels to Select Points with ggrepel? In this post, we will see how to add labels or annotations to select data points such that the labels don't overlap with each other. We will use the R package ggrepel together with ggplot to add labels without overlaps. More specifically we will use geom_text_repel() function from ggrepel to add annotations to data points. Add text labels with ggplot2 - the R Graph Gallery # library library (ggplot2) # Keep 30 first rows in the mtcars natively available dataset data= head (mtcars, 30) # 1/ add text with geom_text, use nudge to nudge the text ggplot (data, aes ( x= wt, y= mpg)) + geom_point () + # Show dots geom_label ( label=rownames (data), nudge_x = 0.25, nudge_y = 0.25, check_overlap = T ) Add one text label only Chapter 4 Labels | Data Visualization with ggplot2 - Rsquared Academy Let us explore the ggtitle () function first. It takes two arguments: label: title of the plot subtitle: subtitle of the plot ggplot(mtcars) + geom_point(aes(disp, mpg)) + ggtitle(label = 'Displacement vs Mileage', subtitle = 'disp vs mpg') 4.4 Axis Labels You can add labels to the axis using: xlab () ylab () labs () Legends (ggplot2) - Cookbook for R Note that this didn't change the x axis labels. See Axes (ggplot2) for information on how to modify the axis labels.. If you use a line graph, you will probably need to use scale_colour_xxx and/or scale_shape_xxx instead of scale_fill_xxx.colour maps to the colors of lines and points, while fill maps to the color of area fills.shape maps to the shapes of points.
