3.9 Adding Labels to a Bar Graph | R Graphics Cookbook, 2nd edition Another common scenario is to add labels for a bar graph of counts instead of values. To do this, use geom_bar (), which adds bars whose height is proportional to the number of rows, and then use geom_text () with counts:

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 Text and annotations in R - Plotly For the pie, bar, sunburst and treemap traces, it is possible to force all the text labels to have the same size thanks to the uniformtext layout parameter. The minsize attribute sets the font size, and the mode attribute sets what happens for labels which cannot fit with the desired fontsize: either hide them or show them with overflow. r-graph-gallery.com › 275-add-text-labels-with-ggplot2Add text labels with ggplot2 – the R Graph Gallery This example demonstrates how to use geom_text() to add text as markers. 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.

How to add data labels in r. Quick-R: Value Labels 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")) # variable y is coded 1, 3 or 5 # we want to attach value labels 1=Low, 3=Medium, 5=High 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 (). add_labels function - RDocumentation add_labels () adds labels to the existing value labels of x, however, unlike set_labels, it does not remove labels that were not specified in labels. add_labels () also replaces existing value labels, but preserves the remaining labels. remove_labels () is the counterpart to add_labels () . It removes labels from a label attribute of x. Data Visualization With R - Title and Axis Labels This is the second post of the series Data Visualization With R.

Add Count and Percentage Labels on Top of Histogram Bars in R hist (…, labels=TRUE,..) Example: R # setting the seed value set.seed(67832) # define x values using the # rnorm method xpos <- rnorm(50) # plotting the histogram hist(xpos , labels = TRUE, ylim=c(0,20)) Output The percentage can be computed using mathematical functions. Initially, the histogram without any labels is stored in a variable. labels function - RDocumentation One can set or extract labels from data.frame objects. If no labels are specified labels (data) returns the column names of the data frame. Using abbreviate = TRUE, all labels are abbreviated to (at least) 4 characters such that they are unique. Other minimal lengths can specified by setting minlength (see examples below).

How to add text labels to a scatter plot in R? - Didier Ruedin To add the labels, we have text (), the first argument gives the X value of each point, the second argument the Y value (so R knows where to place the text) and the third argument is the corresponding label. The argument pos=1 is there to tell R to draw the label underneath the point; with pos=2 (etc.) we can change that position. The scatter ...
