The last example listed below shows a vector with zero elements; the output of any and all in this case may at first be confusing. In that vector, all zero of the values are TRUE, but there aren’t any TRUE values to be found. Missing Values in R Missing Values. A missing value is one whose value is unknown. Missing values are represented in R by the NA symbol.NA is a special value whose properties are different from other values.NA is one of the very few reserved words in R: you cannot give anything this name.

# 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 If you include the NA value in a calculation it will result in an NA value. While this may be okay sometimes in other cases you need a number. The two remove NA values in r is by the na.omit() function that deletes the entire row, and the na.rm logical perimeter which tells the function to skip that value.

Hence I want replace every value in the given column with " Since R 3.4.0, care is taken not to count the excluded values (where they were included in the NA count, previously). The summary method for class "table" (used for objects created by table or xtabs ) which gives basic information and performs a chi-squared test for independence of factors (note that the function chisq.test currently only handles 2-d tables). In my continued playing around with R I’ve sometimes noticed ‘NA’ values in the linear regression models I created but hadn’t really thought about what that meant.
