Efficiently Working with Lists of DataFrames in R: Solutions for Manipulating Individual Elements
Working with Lists of DataFrames in R
When working with multiple dataframes, it’s often necessary to manipulate or transform them individually. However, the nrow() function returns a single value for each dataframe in a list, which can lead to confusion and errors when trying to access specific data from each dataframe.
In this article, we’ll explore how to create a loop that adds a new column to each dataframe in a list, using the unnest function from the tidyr package.
