How to Remove Items from Vector based on a Condition in R

How to Remove Items from Vector based on a Condition in R ?

To remove items from a vector based on a condition in R, you can use the subset function or indexing with logical vectors.

In this example,

We start by creating a vector named vec with some integer values.
We use the subset function to subset the vector based on a condition. The condition is specified using a logical expression where we want to keep elements less than 30.
We store the result in a new vector named vec_new.
Finally, we print the new vector to see the result.

vec <- c(10, 20, 30, 40, 50)
vec_new <- subset(vec, vec &lt; 30)
print(vec_new)

In this example,

We start by creating a vector named vec with some integer values.
We create a logical vector based on the condition that elements should be less than 30.
We use this logical vector to index the original vector, effectively selecting only those elements that satisfy the condition.
We store the result in a new vector named vec_new.
Finally, we print the new vector to see the result.

vec <- c(10, 20, 30, 40, 50)
logical_vector <- vec &lt; 30
vec_new <- vec[logical_vector]
print(vec_new)
