WebFirst, we have to create an example vector with NA values: vec <- c (3, 1, NA, 3, NA, NA, 4) vec # 3 1 NA 3 NA NA 4. As you can see, our example vector contains several numeric values and NAs. If we want to count the number of NA values in our example vector, we can use a combination of the sum and is.na functions: sum (is.na( vec)) # 3. WebExpert Answer Transcribed image text: 7.
