I have a large JSL script that uses column compression several times to keep file sizes managable:
dt << Compress Selected Columns();
My issue is that for columns (both ordinal and nominal) where I have values such as "a","b","c","d","NA", the compression function removes the "NA" values, I assume because it treats them as a Missing Value Code. However, I require the "NA" to remain as it is used in subsequent functions. How can I prevent this, whilst still running the compression?
Many thanks
@txnelson Thanks, but NA isn't listed as a missing value code in column info for at least some of the relevant columns. As I'm creating a large number of columns with JSL it's not practical to manually check/adjust each. Can this be scripted or can missing value codes be globally defined using JSL?
