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 FACTOR in R [CREATE, CHANGE LABELS and CONVERT data] The factor function. The factor function allows you to create factors in R. In the following block we show the arguments of the function with a summarized description. factor(x = character(), # Input vector data levels, # Input of unique x values (optional) labels = levels, # Output labels for the levels (optional) exclude = NA, # Values to be excluded from levels ordered = is.ordered(x ...

R and labelled data: Using quasiquotation to add variable ... - R-bloggers Adding value labels to variables using quasiquotation. 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 ...

How to Label Points on a Scatterplot in R (With Examples) 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. labels: The text to use for the labels. The following code shows how to label a single ... 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 ().

Apply labels in r. A Guide to apply(), lapply(), sapply(), and tapply() in R Use the apply () function when you want to apply a function to the rows or columns of a matrix or data frame. The basic syntax for the apply () function is as follows: apply (X, MARGIN, FUN) X is the name of the matrix or data frame. MARGIN indicates which dimension to perform an operation across (1 = row, 2 = column) 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). APPLY in R with apply() function [with EXAMPLES] In this tutorial you will learn how to use apply in R through several examples and use cases. 1 apply () function in R 1.1 Applying a function to each row 1.2 Applying a function to each column 2 Apply any function to all R data frame 3 Additional arguments of the apply R function 4 Applying a custom function 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. The article consists of three examples for the addition of point labels. To be more precise, the table of content looks like this: 1) Creating Example Data. 2) Example 1: Add Labels to Base R Scatterplot. 3) Example 2: Add Labels to ggplot2 Scatterplot.

11.3 Changing the Text of Facet Labels - R Graphics 11.3.3 Discussion. Unlike with scales where you can set the labels, to set facet labels you must change the data values. Also, at the time of this writing, there is no way to show the name of the faceting variable as a header for the facets, so it can be useful to use descriptive facet labels. With facet_grid () but not facet_wrap (), at this ... 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. 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). 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"))

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. Add custom tick mark labels to a plot in R software - STHDA Change the string rotation of tick mark labels The following steps can be used : Hide x and y axis Add tick marks using the axis () R function Add tick mark labels using the text () function The argument srt can be used to modify the text rotation in degrees. apply_labels function - RDocumentation apply_labels function - RDocumentation expss (version 0.11.1) apply_labels: Set variable labels/value labels on variables in the data.frame Description apply_labels tries automatically detect what is variable label and what are value labels. See also var_lab and val_lab. Usage apply_labels (data, ...) Arguments data data.frame/list ... Add value labels to variables — set_labels • sjlabelled if labels is a vector and x is a data frame, labels will be applied to each column of x. Use labels = "" to remove labels-attribute from x. force.labels Logical; if TRUE, all labels are added as value label attribute, even if x has less unique values then length of labels or if x has a smaller range then length of labels. See 'Examples'.

How to customize Bar Plot labels in R - How To in R Add x-axis Labels The simplest form of the bar plot doesn't include labels on the x-axis. To add labels , a user must define the names.arg argument. In the example below, data from the sample "pressure" dataset is used to plot the vapor pressure of Mercury as a function of temperature. The x-axis labels (temperature) are added to the plot.
