total_miss = cmiss(of _all_); /* Checks every variable in the row */ Use code with caution. Copied to clipboard
Counts missing values for mixed data types without requiring type conversion. Check For Null Values In Sas
If you want to audit an entire dataset rather than filtering row-by-row, use PROC FREQ or PROC MEANS. Missing Values in SAS - ListenData total_miss = cmiss(of _all_); /* Checks every variable
Returns the count of missing numeric arguments. miss_count = nmiss(var1, var2, var3); Use code with caution. Copied to clipboard total_miss = cmiss(of _all_)
If you need to count how many fields are missing across a row, use these specialized functions:
The most versatile way to check for a missing value in a DATA step is the MISSING() function, which works for both numeric and character data.
