How to avoid this warning ?
The only way to avoid this warning is to use the mean() function with vectors having numeric values only. For example, In the above example we can calculate the mean of the minor column as it contains numerical values only:
R
# Create a data frame dataframe <- data.frame(students=c('Bhuwanesh', 'Anil', 'Suraj', 'Piyush', 'Dheeraj'), section=c('A', 'A', 'C', 'C', 'B'), minor=c(87, 98, 71, 89, 82), major=c(80, 88, 84, 74, 70)) # Try to calculate mean of values stored # at the column minor in the dataframe mean(dataframe$minor) |
Output:
