You can use the **|** symbol as an “OR” operator in R.

For example, you can use the following basic syntax to filter for rows in a data frame in R that satisfy condition 1 **or** condition 2:

df[(condition1) | (condition2), ]

The following examples show how to use this “OR” operator in different scenarios.

**Example 1: Use “OR” Operator to Filter Rows Based on Numeric Values in R**

Suppose we have the following data frame in R:

#create data frame df <- data.frame(team=c('A', 'A', 'B', 'B', 'B', 'B', 'C', 'C'), points=c(25, 12, 15, 14, 19, 23, 25, 29), assists=c(5, 7, 7, 9, 12, 9, 9, 4), rebounds=c(11, 8, 10, 6, 6, 5, 9, 12)) #view data frame df team points assists rebounds 1 A 25 5 11 2 A 12 7 8 3 B 15 7 10 4 B 14 9 6 5 B 19 12 6 6 B 23 9 5 7 C 25 9 9 8 C 29 4 12

We can use the following syntax to filter for rows in the data frame where the value in the points column is greater than 20 **or** the value in the assists column is equal to 9:

#filter rows where points > 20 or assists = 9 df[(df$points > 20) | (df$assists == 9), ] team points assists rebounds 1 A 25 5 11 4 B 14 9 6 6 B 23 9 5 7 C 25 9 9 8 C 29 4 12

The only rows returned are the ones where the points value is greater than 20 **or** the assists value is equal to 9.

**Example 2: Use “OR” Operator to Filter Rows Based on String Values in R**

Suppose we have the following data frame in R:

#create data frame df <- data.frame(team=c('A', 'B', 'C', 'D', 'E', 'F', 'G', 'H'), position=c('G', 'G', 'F', 'F', 'C', 'F', 'C', 'C'), conference=c('W', 'W', 'W', 'W', 'E', 'E', 'E', 'E'), points=c(11, 8, 10, 6, 6, 5, 9, 12)) #view data frame df team position conference points 1 A G W 11 2 B G W 8 3 C F W 10 4 D F W 6 5 E C E 6 6 F F E 5 7 G C E 9 8 H C E 12

We can use the following syntax to filter for rows in the data frame where the value in the position column is equal to G **or** the value in the position column is equal to F **or** the value in the team column is equal to H:

#filter rows based on string values df[(df$team == 'H') | (df$position == 'G') | (df$position == 'F'), ] team position conference points 1 A G W 11 2 B G W 8 3 C F W 10 4 D F W 6 6 F F E 5 8 H C E 12

The only rows returned are the ones that meet at least one of the three conditions that we specified.
