Introduction to Data Analysis and Visualization with R


We need to continually alter the characteristics of rows and columns during the data-wrangling process to enable easier formatting and optimization for subsequent steps. Below are some of the most commonly employed methods in data analysis.

## Modify column names

The `colnames()` command lists the column names. This command returns the column names as vectors of string values. 
Column names can be altered by assigning new values to the output of the `colnames()` command.

>**Note:**
The number of new column names and the columns must be equal. Otherwise, the columns without labels are automatically represented as `NA`.
