Hi, as a Newbie with R and former user of ACL/Monarch I have a lot of questions, which I can\'t clear despite all the documentation. -Read Data in How can I --Filter records from a file (exclude recurring headlines) --Filter single fields from complex reports (cut information out of the report like a mask) --Bond records consisting of several lines in plain report file --Possibility to evaluate data files instead of importing them into R (solution for very big plain files > 2 GB) -Analyse Data How can I --classify/summarize data with key field as in ACL (generate a result list with the grouped field and the result field) --Join two tables as in SQL (outer/inner join between two tables) I did read the posting guide carefully and a lot of documents, but can\'t find the answers - I apologize for all inconveniences if I have overlooked something. Greetings Stefan P.S. Is there somebody else who has experiences in ACL as well (Quickstart in R after a change from ACL)?
