Introduction to gghighlight: Highlight ggplot's Lines and Points with ... As gghighlight_* () returns a ggplot object, it is fully customizable just as we usually do with ggplot2 like custom themes and facetting. By default, gghighlight_line () calculates predicate per group, more precisely, dplyr::group_by () + dplyr::summarise (). So if the predicate expression returns multiple values per group, it ends up with an ...

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 (). 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 How to label only certain points in ggplot2 - Stack Overflow plot1 % ggplot (aes (year, mtco2, group = scenario, colour = scenario)) + geom_line (size = 1) + geom_point (size = 2) + scale_x_continuous (name = "year", breaks = c (1990, 2000, 2006, 2020, 2030, 2040, 2050)) + theme_bw () + labs (title = "global co2 emissions projections with and without constraints") plot1a <- plot1 + geom_text (data = …

How to Annotate a Specific Cluster or Group in ggplot2 in R? These groups can be labeled differently in the graph. Method 1: Using geom_mark_circle package The geom_mark_circle geom method allows the user to annotate sets of points via circles.

The reason for this choice is that it makes it the units for font sizes consistent with how other sizes are specified in ggplot2. (There are 72.27 pts in a inch, so to convert from points to mm, just multiply by 72.27 / 25.4).

Because we globally defined x = continent in the ggplot function, we do not have to specify x in the aesthetics layer in the geom_text () functions. Our ggplot () knows exactly where to place our counts on the x-axis. Only for the y-axis, we have to specify y, fill = status, and position ... 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 Construct labelling specification — labeller • ggplot2 Details. In case of functions, if the labeller has class labeller, it is directly applied on the data frame of labels. Otherwise, it is applied to the columns of the data frame of labels.

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 ()).
