Let’s do this in practice: mean ( x2, na . rm = TRUE ) # Use na.rm option # 4.625 We can exclude missing values in a couple different ways. First, if we want to exclude missing values from mathematical operations use the na.rm = TRUEargument. If you do not exclude these values most functions will return an NA. # A vector with missing valuesx<-c(1:4,NA,6:7,NA)# including NA values will produce an NA outputmean(x)## [1] NA# excluding NA values will calculate the mathematical operation for all non-missing valuesmean(x,na.rm=TRUE)## [1] 3.833333. Method 1: Remove or Drop rows with NA using omit() function: 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 .

Function to remove rows containing NAs from a data vector or matrix. Also counts the number of rows remaining, the number of rows deleted, and in the case of a matrix the number of columns. The results are returned in a list for subsequent processing in the calling function. Usage remove.na(xx Step 1) Earlier in the tutorial, we stored the columns name with the missing values in the list called list_na. We will use this list . Step 2) Now we need to compute of the mean with the argument na.rm = TRUE. This argument is compulsory because the columns have missing data, and this tells R to ignore them.
