But if I copy the same text into this forum it doesn't show the boxes. When I drag and drop the variable "Age" into java snippet, or any other node it shows up with squares between each letter. For some odd reason, the longer file headers are acting weird. If I take the first 20 or so rows of data (including the headers) and create a new file with the exact same format, everything works fine. I suspect there is some issue with Java in general on MAC OS X El Capitan using KNIME 3.3.1 because I have never seen this using a PC. The rows still appear in the output of the node. After Step 2, I tried using the rule based row filter to simply filter out the blanks by using MISSING AGE => TRUE, and exclude the TRUEs. After Step 2, I tried using the Missing Value node to replace blanks with the text "null" and it won't even do that.Ģ.2. Then using the String to Number node and all I get are question marks as a result.Ģ.1. I tried manually removing "Unmatched" using a text editor and replacing it with "". I tried replacing "Unmatched" with null, also with "", using Java Snippet and all I get are question marks as a result.Ģ. I want to convert the column to an integer and nothing is working. One column has Age data but if the user did not provide that information it says "Unmatched". I have a data file with 900,000 rows of data.
