| What are the Missing and Impossible values in R language?
Missing values are represented by symbol NA which means (Not Available). And Impossible values represented by symbol Nan(Not a Number). We use NA for both numeric and string data. There is no global way to deal with missing values there are many advanced functions namely modelling functions have several options for dealing with missing values, from pairwise or list-wise deletion of missing values to complex multiple imputation methods and have a default method of eliminating missing data. | | |
