Modify axis, legend, and plot labels — labs • ggplot2 # The plot tag appears at the top-left, and is typically used # for labelling a subplot with a letter. p + labs(title = "title", tag = "A") # If you want to remove a label, set it to NULL. p + labs(title = "title") + labs(title = NULL) 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.

Modify axis, legend, and plot labels using ggplot2 in R Last Updated : 05 Jul, 2021.

Adding Labels to a {ggplot2} Bar Chart - thomasadventure.blog In this post I will walk you through how you can create such labeled bar charts using ggplot2. The data I will use comes from the 2019 Stackoverflow Developer Survey. To make creating the plot easier I will use the bar_chart() function from my ggcharts package which outputs a ggplot that can be customized further using any ggplot2 function. 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 How to Add Labels Directly in ggplot2 in R - GeeksforGeeks To put labels directly in the ggplot2 plot we add data related to the label in the data frame. Then we use functions geom_text() or geom_label() to create label beside every data point. Both the functions work the same with the only difference being in appearance. The geom_label() is a bit more customizable than geom_text(). Method 1: Using geom_text() Putting labels for only the first and the last value of data in R and ... The special treatement (in my case big red ending point & label) can be relatively easily combined with a ggplot of the full series programmatically.

How To Highlight Select Data Points with ggplot2 in R? Here we will see an example of highlighting specific data points in a plot. Let us first load the packages needed, we will mainly be using dplyr and ggplot2 here. 1 2 3 library(dplyr) library(ggplot2) theme_set(theme_bw(base_size = 16)) Let us use the gapminder data from Carpentries website to make plots and highlight data points. 1 2 3 4 5 6 7 8 9 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: Add Label to Straight Line in ggplot2 Plot in R (2 Examples) In order to use the functions of the ggplot2 package, we also have to install and load ggplot2: install.packages("ggplot2") # Install ggplot2 package library ("ggplot2") # Load ggplot2. Now, we can plot our data as follows: ggp <- ggplot ( data, aes ( x, y)) + # Create plot without line geom_point () ggp # Draw plot without line. 14 Build a plot layer by layer | ggplot2 This call fully specifies the five components to the layer: mapping: A set of aesthetic mappings, specified using the aes() function and combined with the plot defaults as described in Section 14.4.If NULL, uses the default mapping set in ggplot().. data: A dataset which overrides the default plot dataset.It is usually omitted (set to NULL), in which case the layer will use the default data ...

Add text labels with ggplot2 - the R Graph Gallery It works pretty much the same as geom_point (), but add text instead of circles. A few arguments must be provided: label: what text you want to display. nudge_x and nudge_y: shifts the text along X and Y axis. check_overlap tries to avoid text overlap. Note that a package called ggrepel extends this concept further.

Chapter 4 Labels | Data Visualization with ggplot2 - Rsquared Academy 4.7 Format Title & Axis Labels. To format the title or the axis labels, we have to modify the theme of the plot using the theme() function. We can modify: color; font family; font face; font size; horizontal alignment; and angle; In addition to theme(), we will also use element_text(). It should be used whenever you want to modify the appearance of any text element of your plot.
