How to Split a Vector in R - Step by Step Examples

How to Split a Vector in R ?

In R, you can split a vector into smaller parts using the split() function.

In this example,

We create a vector named data containing elements with corresponding factor levels.
We use the split() function to split the vector into smaller parts based on the factor levels.
The result is a list where each element corresponds to a factor level and contains the elements from the original vector that belong to that level.

data <- c(1, 2, 3, 4, 5, 6)
factor <- c('A', 'B', 'A', 'B', 'C', 'C')
split_data <- split(data, factor)
print(split_data)

{"A":[1,3],"B":[2,4],"C":[5,6]}

In this example,

We create a vector named data containing numeric values.
We define a condition using a logical vector indicating which elements meet the condition.
We use the split() function along with the condition to split the vector into two parts based on the condition.

data <- c(1, 2, 3, 4, 5, 6)
condition <- data > 3
split_data <- split(data, condition)
print(split_data)

{"FALSE":[1,2,3],"TRUE":[4,5,6]}

In this tutorial, we learned How to Split a Vector in R language with well detailed examples.
