However, this R code can easily be modified to retain rows with a certain amount of NAs. For instance, if you want to remove all rows with 2 or more missing values, you can replace “== 0” by “>= 2”. Example 4: Removing Rows with Some NAs Using drop_na() Function of tidyr Package In the following, I have prepared examples for the most important R functions that can be combined with is.na. Remove NAs of Vector or Column In a vector or column, NA values can be removed as follows: is.na_remove <- data$x_num [!is.na(data$x_num)] If we want to remove multiple values from a vector, we can use the %in% operator. Have a look at the following R code: vec_new <- vec [! vec % in % c ("A", "C")] # Remove multiple values vec_new # Print updated vector # "B" "D" As you can see based on the output of the RStudio console, we deleted every “A” and every “C” from our vector. Remove all rows with NA From the above you see that all you need to do is remove rows with NA which are 2 (missing email) and 3 (missing phone number).
