Sometimes we split one dataset into multiple sets and in the same way we merge multiple datasets into one. As a data scientist these are the common tasks in our day to day life.

  • Example 1 relied on the basic installation of R (or RStudio). However, the tidyverse add-on package provides a very smooth and simple solution for combining multiple data frames in a list simultaneously. Let’s install and load the tidyverse packages (to be precise – we need the dplyr and the purrr packages for the following example): install.packages('tidyverse') # Install tidyverse package library ('tidyverse') # Load tidyverse package.
  • Often you may want to combine two columns into one in R. For example, suppose you have a data frame with three columns: month year value 10 2019 22.

I have one data frame name titanic_train_ds with 12 variables and 891 observations. Let’s see the data frame at a glance:

I have another data frame named titanic_test_ds with 12 variables and 418 observations. Let’s see the data frame at a glance

Combine Dataframes

Both data frame have same number of columns, similar number of data types but different numbers of observations. We wanted to combined these two data frames into one named titanic_full_ds. So, let’s see how to combine or merge these two data frames into one in R:
