Hi Arne If you are reading in from files and they are just one number per line it would be more efficient to use scan directly. ?scan
For example: > filen<-"C:/temp/tt.txt" > i<-scan(filen) Read 5 items > i [1] 12345 564376 5674 6356656 5666 > -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: 01 November 2006 15:47 To: r-help@stat.math.ethz.ch Subject: [R] splitting very long character string Hello, I've a very long character array (>500k characters) that need to split by '\n' resulting in an array of about 60k numbers. The help on strsplit says to use perl=TRUE to get better formance, but still it takes several minutes to split this string. The massive string is the return value of a call to xmlElementsByTagName from the XML library and looks like this: ... 12345 564376 5674 6356656 5666 ... I've to read about a hundred of these files and was wondering whether there's a more efficient way to turn this string into an array of numerics. Any ideas? thanks a lot for your help and kind regards, Arne [[alternative HTML version deleted]] ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
