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).

FACTOR in R [CREATE, CHANGE LABELS and CONVERT data] On the one hand, the labels argument allows you to modify the factor levels names. Hence, the labels argument it is related to output. Note that the length of the vector passed to the labels argument must be of the same length of the number of unique groups of the input vector. factor(gender, labels = c("f")) Output f f f f Levels: f

Renaming levels of a factor - Cookbook for R # Rename by name: change "beta" to "two" levels(x) [levels(x)=="beta"] <- "two" # You can also rename by position, but this is a bit dangerous if your data # can change in the future. If there is a change in the number or positions of # factor levels, then this can result in wrong data. Modify ggplot X Axis Tick Labels in R | Delft Stack In this case, we utilize scale_x_discrete to modify x axis tick labels for ggplot objects. Notice that the first ggplot object is a bar graph based on the diamonds data set. The graph uses the cut column and plots the count of each type on the y axis. x axis has the default title - cut, which can be modified by passing the string as the first ... Change Labels of GGPLOT2 Facet Plot in R - GeeksforGeeks Method 2: Using levels () As we discussed previously the LBLs variable of DataFrame is responsible for Labels of Facet, so now we will create a new DataFrame and assign old DataFrame DF to it. Then simply change the Values of Labels variable of the new DataFrame. Here we use levels () function to set the attribute of a variable in a new manner.

Change labels in r. 8.8 Changing the Text of Tick Labels - R Graphics To set arbitrary labels, as in Figure 8.15 (right), pass values to breaks and labels in the scale. One of the labels has a newline ( \n) character, which tells ggplot to put a line break there: hw_plot + scale_y_continuous( breaks = c(50, 56, 60, 66, 72), labels = c("Tiny", "Really\nshort", "Short", "Medium", "Tallish") ) Add custom tick mark labels to a plot in R software - STHDA Changing the rotation angle is not something easy in R but we'll see how to do it in the next section. # Hide x and y axis plot(x, y, xaxt="n", yaxt="n") 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 How to Relabel Rows and Columns in an R Table - Displayr Help Select the table you wish to copy the labels from. 2. Copy the name from Properties > GENERAL > Name. 3. Select the R table you wish to update. 4. In the object inspector, go to Properties > R CODE. 5. To update all the table's column names with that of the table from steps 1 and 2, add a line to the code: Change Axis Labels of Boxplot in R - GeeksforGeeks Horizontal boxplot with changed labels Method 2: Using ggplot2 If made with ggplot2, we change the label data in our dataset itself before drawing the boxplot. Reshape module is used to convert sample data from wide format to long format and ggplot2 will be used to draw boxplot.

How to change the axes labels using plot function in R? R Programming Server Side Programming Programming. In a plot, the axes labels help us to understand the range of the variables for which the plot is created. While creating a plot in R using plot function, the axes labels are automatically chosen but we can change them. To do this, firstly we have to remove the axes then add each of the axes ... 10.8 Changing the Labels in a Legend - R Graphics # create the base plot hw_plot <- ggplot(heightweight, aes(x = ageyear, y = heightin, shape = sex, colour = sex)) + geom_point() hw_plot # change the labels for one scale hw_plot + scale_shape_discrete(labels = c("female", "male")) # change the labels for both scales hw_plot + scale_shape_discrete(labels = c("female", "male")) + … 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")) How to customize Bar Plot labels in R - How To in R Click to set custom HTML Add Axis Titles Axis titles can be added via the xlab and ylab arguments. barplot (ElementContainingData, xlab = "LabelText", ylab = "LabelText" ) Example > barplot (pressure$pressure, names.arg = pressure$temperature, xlab = "Temperature", ylab = "Pressure") Customize Axis Titles

Change Legend Labels of ggplot2 Plot in R (2 Examples) ggp + # Modify labels and colors scale_color_manual ( labels = c ("Group 1", "Group 2", "Group 3") , values = c ("red", "blue", "green")) As shown in Figure 2, we have modified the text of the legend items with the previous R programming code. Note that the previous R code also change the color of the data points in our scatterplot. R plot() Function (Add Titles, Labels, Change Colors and Overlaying Pots) Adding Titles and Labeling Axes We can add a title to our plot with the parameter main. Similarly, xlab and ylab can be used to label the x-axis and y-axis respectively. plot (x, sin (x), main="The Sine Function", ylab="sin (x)") Changing Color and Plot Type We can see above that the plot is of circular points and black in color. Change Table Names & Labels in R (2 Examples) | How to Modify & Adjust Table Names & Labels in R (2 Examples) In this R programming tutorial you'll learn how to change the names and labels of a table object. Table of contents: 1) Example Data. 2) Example 1: Change Column Names of Table Object. 3) Example 2: Change Row Names of Table Object. 4) Video & Further Resources. Setting the Font, Title, Legend Entries, and Axis Titles in R You can set the figure-wide font with the layout.font.family attribute, which will apply to all titles and tick labels, but this can be overridden for specific plot items like individual axes and legend titles etc. In the following figure, we set the figure-wide font to Courier New in blue, and then override this for certain parts of the figure.

Axes customization in R | R CHARTS Remove axis labels You can remove the axis labels with two different methods: Option 1. Set the xlab and ylab arguments to "", NA or NULL. # Delete labels plot(x, y, pch = 19, xlab = "", # Also NA or NULL ylab = "") # Also NA or NULL Option 2. Set the argument ann to FALSE.

How can I change the angle of the value labels on my axes? | R FAQ If we want to adjust the labels on the horizontal axis, we must first alter our graphics parameters so that we suppress the horizontal axis that usually appears with the graph. First, we save our current settings for the graphics parameters so that we can restore them later. Then we change our x-axis type, or xaxt, to "n".

labels.rpart function - RDocumentation The returned set of labels is always of the same length as the number of nodes in the tree. If collapse = TRUE (default), the returned value is a vector of labels for the branch leading into each node, with "root" as the label for the top node. If FALSE, the returned value is a two column matrix of labels for the left and right branches leading ...

Add, replace or remove value labels of variables — add_labels Details. 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 () .

Changing the names of labels and legend - RStudio Community Changing the names of labels and legend. Although I initially had lots of troubles realizing my likert plot, I now managed to do so. I have created a plot I'm happy with, such as the one attached. I already managed to change the names of "Community1" and "Community2". Instead of "econ_comm" I would like to have the original question, e.g.

Variable and value labels support in base R and other packages Variable label is human readable description of the variable. R supports rather long variable names and these names can contain even spaces and punctuation but short variables names make coding easier. Variable label can give a nice, long description of variable. With this description it is easier to remember what those variable names refer to.
