Counting True Values in R
To count the true values in R, you can use the sum
function along with the logical condition. Here are the steps:
Create a Logical Vector: First, create a logical vector containing the values you want to count. For example, if you have a vector
x
and you want to count the number ofTRUE
values, you can create a logical vector using a condition likex == TRUE
.Use the
sum
Function: Then, use thesum
function to count the number ofTRUE
values in the logical vector. Thesum
function treatsTRUE
as 1 andFALSE
as 0, so summing the logical vector will give you the count ofTRUE
values.
Here's an example of how you can count the number of TRUE
values in a vector x
:
# Create a sample vector
x <- c(TRUE, FALSE, TRUE, TRUE, FALSE, TRUE)
# Count the number of TRUE values
count_true <- sum(x == TRUE)
count_true
This will output the count of TRUE
values in the vector x
.
