How to Convert a Set of Strings to a Set of Integers in R - Step by Step Examples

How to Convert a Set of Strings to a Set of Integers in R ?

In R, you can convert a set of strings to a set of integers using the as.integer() function.

In this example,

We have a set named string_set1 containing the elements '1', '2', '3', '4', '5'.
We use the as.integer() function to convert each string element to an integer.
We store the converted integers in a new set named int_set1.
We print the resulting int_set1 to the console.

string_set1 <- c('1', '2', '3', '4', '5')
int_set1 <- as.integer(string_set1)
print(int_set1)

[1] 1 2 3 4 5

In this example,

We have a set named string_set2 containing the elements '10', '20', '30', '40', '50'.
We use the sapply() function to apply the as.integer() function to each element of string_set2.
We store the converted integers in a new set named int_set2.
We print the resulting int_set2 to the console.

string_set2 <- c('10', '20', '30', '40', '50')
int_set2 <- sapply(string_set2, as.integer)
print(int_set2)

[1] 10 20 30 40 50
