I want to count the number of NA values in a data frame column. Say my data frame is called df, and the name of the column I am considering is col. The way I have come up with is following: sapp Definition of NA: NA stands for Not Available and is used whenever a value is missing (e.g. due to survey nonresponse).

If you do not exclude these values most functions will return an NA . # A vector with missing values x <- c ( 1 : 4 , NA , 6 : 7 , NA ) # including NA values will produce an NA output mean ( x ) ## [1] NA # excluding NA values will calculate the mathematical operation for all non-missing values mean ( x , na.rm = TRUE ) ## [1] 3.833333 (Optional) If omitted (and no variable named n exists in the data), will count the number of rows. If specified, will perform a "weighted" tally by summing the (non-missing) values of variable wt . A column named n (but not nn or nnn ) will be used as weighting variable by default in tally() , but not in count() .

If there are NA’s in the data, you need to pass the flag na.rm=TRUE to each of the functions.length() doesn’t take na.rm as an option, so one way to work around it is to use sum(!is.na()) to count how many non-NA’s there are.

Description. This method counts tagged NA values (see tagged_na) in a vector and prints a frequency table of counted tagged NAs. Usage. 1. This is a translation of the SQL command NULLIF. It is useful if you want to convert an annoying value to NA. count_na: Count the number of NAs in each row or in each column; d.eta: Sample data set for eta function examples; d.ngo: NGO Dataset; d.superiority: Student self assessment data; eta: Eta coefficient for nominal/interval data. foo: A function to demonstrate how an R function is defined.
