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 . # 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

Theory. It is often the case, when importing data into R, that we have more than one or two data frames with raw data. In this tutorial, I’ll be going over some methods in R that will help you identify, visualize and remove outliers from a dataset. Looking at Outliers in R As I explained earlier, outliers can be dangerous for your data science activities because most statistical parameters such as mean, standard deviation and correlation are highly sensitive to outliers. (a)To remove all rows with NA values, we use na.omit() function.. In your case: final <- na.omit(dataframe) Output: a b c d e f. 2 YASH00000199774 0 2 2 2 2 Now it is possible to find NA values by running the code to check each value, but unless you have a special need for this is.na() function will do the job.
