9.6 Missing Values in Rattle

In Rattle we use mice::md.pattern() to generate a table of the patterns of missing values. Each row corresponds to a pattern of missing values with 1 representing not missing and 0 representing missing. The first column is the count of times this pattern (combination of columns with missing data) occurs - the number of observations. The final column is the count of the number of variables with missing values. The final row the number of observations with missing values for the particular variable.
