NA is a logical constant of length 1 which contains a missing value indicator. NA can be coerced to any other vector type except raw. There are also constants NA_integer_, NA_real_, NA_complex_ and NA_character_ of the other atomic vector types which support missing values: all of these are reserved words in the R language. stri_remove_empty (alias stri_omit_empty) removes all empty strings from a character vector, and, if na_empty is TRUE, also gets rid of all missing values. stri_remove_empty_na (alias stri_omit_empty_na) removes both empty strings and missing values.

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)] 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). First, let's apply the complete.cases() function to the entire dataframe and see what results it produces: If remove contains incomparables, you'll have to check for them individually, e.g. if (any (is.na (remove))) a <- a [! is.na (a)] (This does not distinguish NA from NaN but the R manual anyways warns that one should not rely on having a difference between them) For Inf/ … 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.
