Consider the following example vector: x <- c (5, 9, NaN, 3, 8, NA, NaN) # Create example vector in R. x <- c (5, 9, NaN, 3, 8, NA, NaN) # Create example vector in R. returns TRUE if the value is NA, so to find how many are not NA, the result is reversed using ' ! Similar logic can be used to find how many meet any logical condition (e.g., sum(1:10 < 5) ).

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().This argument is automatically quoted and later learn how to emulate Excel/SQL count() functions in R (which doesn't have a count function)You can copy the step by step code here: or download the R file fr Here’s a feature of dplyr that occasionally bites me (most recently while making these graphs).It’s about to change mostly for the better, but is also likely to bite me again in the future. If you want to follow along there’s a GitHub repo with the necessary code and data.. Say we have a data frame or tibble and we want to get a frequency table or set of counts out of it. When you in R count the number of occurrences in a column, it can help reveal those relationships. When counting the occurence of distinct values, it gives you new information about the data set.

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 There are a number of ways in R to count NAs (missing values). A common use case is to count the NAs over multiple columns, ie., a whole dataframe. That’s basically the question “how many NAs are there in each column of my dataframe”?
