Change Legend Labels of ggplot2 Plot in R (2 Examples) 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. Example 2: Rename Factor Levels to Change Legend Labels of ggplot2 Plot 15.8 Changing the Order of Factor Levels - R Graphics 15.8.2 Solution. Pass the factor to factor (), and give it the levels in the order you want. This returns a new factor, so if you want to change the original variable, you'll need to save the new result over it. The order can also be specified with levels when the factor is first created:

How to Reorder Factor Levels in R (With Examples) - Statology How to Reorder Factor Levels in R (With Examples) Occasionally you may want to re-order the levels of some factor variable in R. Fortunately this is easy to do using the following syntax: factor_variable <- factor(factor_variable, levels=c ('this', 'that', 'those', ...)) The following example show how to use this function in practice.

Change factor labels in r

15.10 Changing the Names of Factor Levels - R Graphics With this method, all factor levels must be specified in the list; if any are missing, they will be replaced with NA. It's also possible to rename factor levels by position, but this is somewhat inelegant: 10.8 Changing the Labels in a Legend - R Graphics If you are also changing the order of items in the legend, the labels are matched to the items by position. In this example we'll change the item order, and make sure to set the labels in the same order (Figure 10.14 ): pg_plot + scale_fill_discrete( limits = c("trt1", "trt2", "ctrl"), labels = c("Treatment 1", "Treatment 2", "Control") ) How to Change the Levels of a Factor in R - ProgrammingR We have two factors (wool, tension). We want to rename factor levels in r so they are easier to understand. Let's take look at their values: # look at factor levels in r for wool > levels (warpbreaks$wool) [1] "A" "B" # look at factor levels in r for tension > levels (warpbreaks$tension) [1] "L" "M" "H"

Change factor labels in r. How to Rename Factor Levels in R using levels() and dplyr One simple method to rename a factor level in R is levels (your_df$Category1) [levels (our_df$Category1)=="A"] <- "B" where your_df is your data frame and Category1 is the column containing your categorical data. Now, this would recode your factor level "A" to the new "B". How do I Rename Factor Levels in R? How to Rename and Relevel Factors in R - Predictive Hacks A "special" data structure in R is the "factors". We are going to provide some examples of how we can rename and relevel the factors. For the next examples, we will work with the following data ... Another way to change the order is to use relevel() to make a particular level first in the list. (This will not work for ordered factors ... How to Convert Character to Factor in R (With Examples) We can use the following syntax to convert a character vector to a factor vector in R: factor_vector <- as. factor (character_vector) This tutorial provides several examples of how to use this function in practice. Example 1: Convert a Vector from Character to Factor. The following code shows how to convert a character vector to a factor vector: Change Labels of ggplot2 Facet Plot in R - Statistics Globe Let's do this: data_new <- data # Replicate data levels ( data_new$group) <- c ("Label 1", "Label 2", "Label 3") # Change levels of group We have created a new data frame called data_new that contains different factor levels. Now, we can apply basically the same ggplot2 code as before to our new data frame.

as_factor : Convert variable into factor and keep value labels This function is intended for use with vectors that have value and variable label attributes. Unlike as.factor, as_factor converts a variable into a factor and preserves the value and variable label attributes. Adding label attributes is automatically done by importing data sets with one of the read_*-functions, like read_spss. 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 How to Convert Factor to Numeric in R (With Examples) How to Convert Factor to Numeric in R (With Examples) We can use the following syntax to convert a factor vector to a numeric vector in R: numeric_vector <- as.numeric(as.character(factor_vector)) We must first convert the factor vector to a character vector, then to a numeric vector. This ensures that the numeric vector contains the actual ...
