Hi, how can I import really big plain text data files (several GB) from an ERP-System (SAP-Tables) to R? The Header of these files are always similar, for example:
Tabelle: T009 Angezeigte Felder: 7 von 7 Feststehende F�hrungsspalten: 2 Listbreite 0250 ---------------------------------------------------------------------- |X|MANDT|PERIV|XKALE|XJABH|ANZBP|ANZSP|LTEXT | ---------------------------------------------------------------------- |X|001 |01 |X | |012 |02 |ABC | |X|001 |V9 | | |012 |04 |Okt. - Sep., 4 Sonderperioden | |X|001 |WK | |X |053 |00 |Kalenderwochen | ---------------------------------------------------------------------- (including the first 5 rows in each downloaded table, row # 4 =field names, length of 1 row > 1023 bytes, count of fields > 256, size = several GB, count records = several million) What is an appropriate way to read such tables in? Greetings Stefan P.S. I am a beginner with R. Until now I have used ACL (http://www.acl.com) for data mining purposes and I'm doing now my first try with R. Yes, I have [X] Read R Data Import/Export [X] Read Using R for Data Analysis [X] Read Simple R [X] Read Manuals [X] Read read.table() and scan() command ______________________________________________ [EMAIL PROTECTED] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
