I'm super new to R overall and I'm working with a long dataframe with the ultimate goal of creating a density plot. The dataframe is just two variables of heights; one fheight and the other sheight for father and son respectively. I need to rearrange this data so that the varibles are in another column "relationships" with father and son and the corresponding heights (160, 175, etc...).
library(dplyr)
| father_height | son_height | 
|---|---|
| 165.2 | 151.8 | 
| 160.7 | 160.6 | 
| 165.0 | 160.9 | 
The ultimate goal here is to create a density plot with both of these measured. Any help would be amazing.
ETA: My expected output would be similar to below:
| relationships | heights | 
|---|---|
| father | 165.2 | 
| son | 151.8 | 
| father | 160.7 |
