ProgramGuruTo check if a vector contains all the items of another vector in R, you can use the all function combined with the %in% operator.
In this example,
vector1 with a set of numerical values.vector2 with a different set of numerical values.all function combined with the %in% operator to check if all elements of vector2 are present in vector1. The %in% operator returns a logical vector indicating if there is a match or not for its left operand in its right operand.all function checks if all values in the logical vector are TRUE. If all elements of vector2 are in vector1, it returns TRUE; otherwise, it returns FALSE.print function.vector1 <- c(1, 2, 3, 4, 5)
vector2 <- c(2, 3, 4)
result <- all(vector2 %in% vector1)
print(result)TRUE
In this example,
main_vector with a series of character strings.sub_vector with a subset of character strings.all function combined with the %in% operator to check if all elements of sub_vector are present in main_vector. The %in% operator returns a logical vector indicating the presence of each element of sub_vector in main_vector.all function checks if every value in this logical vector is TRUE. If all elements of sub_vector exist in main_vector, it will return TRUE. Otherwise, it will return FALSE.print function.main_vector <- c("apple", "banana", "cherry", "date", "fig")
sub_vector <- c("banana", "cherry", "date")
result <- all(sub_vector %in% main_vector)
print(result)TRUE
In this example,
primary_vector with a list of mixed data types including numbers and strings.secondary_vector with some elements that are not present in primary_vector.all function combined with the %in% operator to check if all elements of secondary_vector are present in primary_vector. The %in% operator returns a logical vector for each element of secondary_vector indicating if it is found in primary_vector.all function checks this logical vector to see if all values are TRUE. Since not all elements of secondary_vector are in primary_vector, it returns FALSE.print function.primary_vector <- c(10, 20, 30, "apple", "banana")
secondary_vector <- c(20, "banana", "cherry")
result <- all(secondary_vector %in% primary_vector)
print(result)FALSE
In this tutorial, we learned How to check if a Vector contains all the items of Another Vector in R language with well detailed examples.
