Filter Rows Based on Conditions in a DataFrame in R

To filter rows in a data frame using R, we can apply conditions directly to the columns. R offers several ways to perform this, depending on whether the condition is single or multiple.

1. Filter Rows Based on a Single Condition

Example: Filter rows where id > 400

Output:

Example: Filter rows where age > 35

Output:

2. Filter Rows Based on Multiple Conditions

This method filters rows where multiple conditions are checked using logical operators like &, | or %in%.

Example: Filter rows where age > 30 and id == 450

Output:

Example: Filter rows where name is "b" or "e"
