How to Remove Items from Set based on a Condition in R - Step by Step Examples

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

To remove items from a set based on a condition in R, you can use the subset function along with a logical condition to filter out the items.

In this example,

We create a vector named number_set containing integer values 1, 2, 3, 4, and 5.
We use the subset function with a logical condition that checks for odd numbers to keep them in the set.
Finally, we print the modified vector number_set to see the removed items.

number_set <- c(1, 2, 3, 4, 5)
number_set <- subset(number_set, number_set %% 2 != 0)
print(number_set)

[1] 1 3 5

In this example,

We create a vector named string_set containing string values 'apple', 'banana', 'cherry', 'date', and 'grape'.
We use the subset function with a logical condition that checks for string length greater than or equal to 6 characters to keep them in the set.
Finally, we print the modified vector string_set to see the removed items.

string_set <- c('apple', 'banana', 'cherry', 'date', 'grape')
string_set <- subset(string_set, nchar(string_set) >= 6)
print(string_set)

[1] "banana" "cherry"
