How to use full join In R Language
In this method of joining data, the user calls the right_join function and this will result in jointed data of all the rows from the joined tables,
full_join() function:
This function includes all rows.
Syntax:
full_join(x, y, by = NULL, on = NULL)
Parameters:
- x: A data.table
- y: A data.table
- by: A character vector of variables to join by.
- on: Indicate which columns in x should be joined with which columns in y.
Example:
In this example, we will be using the full_join() function from the dplyr package to join two different data as shown in the image above in the R programming language.
R
# load library library("dplyr") # create dataframe gfg1<-data.frame(ID=c(1:5)) gfg2<-data.frame(ID=c(4:8)) # perform full join full_join(gfg1,gfg2, by = "ID") |
Output:
ID 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8
