How to display categorical column name in facet grid in R?
To display categorical column name in facet grid, we can use the following steps −
- First of all, creating data frame.
- Loading ggplot2 package and creating a chart with facets
- Creating the chart with facets and labeller function to display categorical column name
Create the data frame
Let's create a data frame as shown below −
x<-rnorm(20)
y<-rnorm(20)
Factor<-sample(c("I","II","III"),20,replace=TRUE)
df<-data.frame(x,y,Factor)
dfOn executing, the above script generates the below output(this output will vary on your system due to randomization) −
x y Factor 1 -1.2961065 -1.3092987 I 2 0.5337357 0.2291017 I 3 1.7851655 -0.4845764 I 4 1.0809707 0.1879267 I 5 -0.7360667 -0.8993411 II 6 -2.1703410 -1.3451734 I 7 1.1761357 0.1834939 II 8 1.4432419 1.0218972 II 9 -0.2989334 -0.2337353 III 10 0.5419797 0.3144817 II 11 -1.2864239 -1.7106241 I 12 -1.0866636 1.2598880 I 13 -0.6756130 -0.2291350 I 14 -1.4876827 -0.4388541 III 15 -2.1607323 0.3629047 II 16 0.9352823 0.5710842 III 17 1.1757290 1.0738887 III 18 0.5019893 -0.5860239 II 19 -1.3477106 1.4709259 III 20 0.8654047 -1.4147550 III
Loading ggplot2 package and creating facetted chart
Create a point chart for groups displayed in facets −
library(ggplot2)
x<-rnorm(20)
y<-rnorm(20)
Factor<-sample(c("I","II","III"),20,replace=TRUE)
df<-data.frame(x,y,Factor)
ggplot(df,aes(x,y))+geom_point()+facet_grid(~Factor)Output
Creating facetted chart with categorical column name in facet grid
Use labeller function of ggplot2 package to create the point chart with facets having Factor column values displayed in facets −
x<-rnorm(20)
y<-rnorm(20)
Factor<-sample(c("I","II","III"),20,replace=TRUE)
df<-data.frame(x,y,Factor)
ggplot(df,aes(x,y))+geom_point()+facet_grid(~Factor,labeller=labeller(.rows=label_both,
.cols=label_both))Output
