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 (). Variable and value labels support in base R and other packages In addition to apply_labels we have SPSS-style var_lab and val_lab functions: nps = c(-1, 0, 1, 1, 0, 1, 1, -1) var_lab(nps) = "Net promoter score" val_lab(nps) = num_lab(" -1 Detractors 0 Neutralists 1 Promoters ")

Change Axis Labels of Boxplot in R (2 Examples) Example 1: Change Axis Labels of Boxplot Using Base R. In this section, I'll explain how to adjust the x-axis tick labels in a Base R boxplot. Let's first create a boxplot with default x-axis labels: boxplot ( data) # Boxplot in Base R. The output of the previous syntax is shown in Figure 1 - A boxplot with the x-axis label names x1, x2 ... label function - RDocumentation label can optionally append a "units" attribute to the string, and it can optionally return a string or expression (for R 's plotmath facility) suitable for plotting. labelPlotmath is a function that also has this function, when the input arguments are the 'label' and 'units' rather than a vector having those attributes.

Apply labels in r. How to apply manually created x-axis labels in a histogram created by ... Therefore, firstly we need to create the histogram by ignoring the labels and then axis function can be used for new values. Consider the below vector x and create a histogram of x by ignoring x-axis labels − Example set.seed(1999) x<-rnorm(5000,9,1) hist(x,xaxt='n') Output Now adding new values for x-axis labels − Example Change Labels of GGPLOT2 Facet Plot in R - GeeksforGeeks Now let us explore different approaches to change the labels. Method 1: Combine Label Variable with Facet Labels . If we want to combine Label Variable (LBLs) to Facet Labels (Values of LBLs), then for that we simply have to use labeller parameter of facet_grid() and set label_both to its value. Example 1: Add value labels to variables — set_labels • sjlabelled labels. (Named) character vector of labels that will be added to x as "labels" or "value.labels" attribute. if labels is not a named vector, its length must equal the value range of x, i.e. if x has values from 1 to 3, labels should have a length of 3; if length of labels is intended to differ from length of unique values of x, a warning is given. Draw Scatterplot with Labels in R (3 Examples) | Base R & ggplot2 The article consists of three examples for the addition of point labels.

R: Add value labels to variables R: Add value labels to variables set_labels {sjlabelled} R Documentation Add value labels to variables Description This function adds labels as attribute (named "labels" ) to a variable or vector x, resp. to a set of variables in a data frame or a list-object.

Tables with labels in R We can save labelled dataset as *.csv file with accompanying R code for labelling. write_labelled_csv(w, file filename = "product_test.csv") Or, we can save dataset as *.csv file with SPSS syntax to read data and apply labels.

R: Assign variable labels of data frame columns - NewbeDEV Here's the original answer for archival purposes: You can assign the labels using lapply: 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 ... labels.data.frame : Extract labels from and set labels for data frames 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. If labels are set (attached to a data.frame) the data.frame gets a special class labeled.data.frame with specific subset and combination functions. Add 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. Note that a package called ggrepel extends this concept further Quick-R: Variable Labels describe (mydata) Unfortunately the label is only in effect for functions provided by the Hmisc package, such as describe (). Your other option is to use the variable label as the variable name and then refer to the variable by position index. names (mydata) [3] <- "This is the label for variable 3" mydata [3] # list the variable To Practice

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).

expss: Tables with Labels in R - GitHub Pages 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.
