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 (). 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"))

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).

R: Assign variable labels of data frame columns - Stack Overflow label (data) = lapply (names (data), function (x) var.labels [match (x, names (var.labels))]) lapply applies a function to each element of a list or vector. In this case the function is applied to each value of names (data) and it picks out the label value from var.labels that corresponds to the current value of names (data).

Apply labels in r. R Basics | Labeling - Stats Education R Basics | Labeling Labeling It is very important when making graphs to be able to label features. We will look at various ways in which we can label our graphics now. Labeling the Axes We can add a lot of features to the axes but for now we will just change labels. We use xlab and ylab for this, if we set them to NULL we have blank axes labels. Create a labelled vector. — labelled • haven A labelled vector is a common data structure in other statistical environments, allowing you to assign text labels to specific values. This class makes it possible to import such labelled vectors in to R without loss of fidelity. This class provides few methods, as I expect you'll coerce to a standard R class (e.g. a factor()) soon after importing. Display All X-Axis Labels of Barplot in R (2 Examples) Example 1: Show All Barchart Axis Labels of Base R Plot. Example 1 explains how to display all barchart labels in a Base R plot. There are basically two major tricks, when we want to show all axis labels: We can change the angle of our axis labels using the las argument. We can decrease the font size of the axis labels using the cex.names argument. Label Encoding in R programming - All you need to know! Before diving deep into the concept of Label Encoding, let us understand about its emergence as a technique in the domain of Data Science and Machine Learning. To recall, Machine Learning algorithmsbroadly deal with structured and unstructured data i.e. the data which contains labels as well as unlabeled data values. In Supervised Learning algorith...

Draw Scatterplot with Labels in R (3 Examples) | Base R & ggplot2 In this post, I'll explain how to add labels to a plot in the R programming language.

Usually, set_labels() can be used to add value labels to variables.The syntax of this function is easy to use, and set_labels()allows to add value labels to multiple variables at once, if these variables share the same value labels. In the following examples, we will use the frq() function, that shows an extra label-column containing value ...

Variable and value labels support in base R and other packages The usual way to connect numeric data to labels in R is factor variables. However, factors miss important features which the value labels provide. Factors only allow for integers to be mapped to a text label, these integers have to be a count starting at 1 and every value need to be labelled.

The best way to attach labels to numeric variables - RStudio Community Factor works but the script gets really long and it takes a very long time to read the data in. Using the forcats package you can get the unique factor levels for a set of observations by converting to factor after you've read in the data with as_factor().. Once you've read your data in, you can recode the factors with their labels, if you so choose (see thread below).
