First, if we want to exclude missing values from mathematical operations use the na.rm = TRUE argument. If you do not exclude these values most functions will return an NA. To delete a column, provide the column number as index to the Dataframe.

Another R tip. Get in the habit of using drop = FALSE when indexing (using [ , ] on) data.frames. Prince Rupert’s drops (img: Wikimedia Commons) In R, single column data.frames are often converted to vectors when manipulated.

complete.cases() – returns vector of rows with na values Drop rows with missing values in R (Drop NA, Drop NaN) : Method 1 . Using na.omit() to remove (missing) NA and NaN values. df1_complete <- na.omit(df1) # Method 1 - Remove NA df1_complete so after removing NA and NaN the resultant dataframe will be. Method 2 . Using complete.cases() to remove (missing) NA and NaN values. df1[complete.cases(df1),] so after removing NA and NaN the resultant dataframe will be The output is the same as in the previous examples. 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”.
