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 = TRUE argument. If you do not exclude these values most functions will return an NA. na.exclude differs from na.omit only in the class of the "na.action" attribute of the result, which is "exclude". This gives different behaviour in functions making use of naresid and napredict : when na.exclude is used the residuals and predictions are padded to the correct length by inserting NA s for cases omitted by na.exclude . Se hela listan på stats.idre.ucla.edu In a vector or column, NA values can be removed as follows: is.na_remove <- data$x_num [!is.na( data$x_num)] is.na_remove <- data$x_num [!is.na (data$x_num)] Note: Our new vector is.na_remove is shorter in comparison to the original column data$x_num, since we use a filter that deletes all missing values.
