How to Filter Items of a Vector based on a Condition in R ?

Answer

To filter items of a vector based on a condition in R, you can use the subset function or logical indexing.

✐ Examples

1 Filter Items Greater Than a Threshold

In this example,

First, you define a vector containing the elements you want to filter.
Next, you specify the condition for filtering, such as greater than a threshold.
Then, you use the subset function or logical indexing to select the items that satisfy the condition.

R Program

# Define a vector containing elements
vector <- c(1, 5, 10, 15, 20)

# Specify the threshold for filtering
threshold <- 10

# Use subset function to filter items greater than the threshold
filtered_vector <- subset(vector, vector > threshold)

# Print the filtered vector
print(filtered_vector)

Output

[15, 20]

2 Filter Items Meeting a Condition

In this example,

Define a vector containing elements.
Specify the condition for filtering.
Use logical indexing to select the items that meet the condition.

R Program

# Define a vector containing elements
vector <- c(1, 5, 10, 15, 20)

# Specify the condition for filtering
condition <- vector %% 2 == 0  # Select even numbers

# Use logical indexing to filter items meeting the condition
filtered_vector <- vector[condition]

# Print the filtered vector
print(filtered_vector)

Output

[10, 20]
