This is a useful reference on the tryCatch() function: http://www1.maths.lth.se/help/R/ExceptionHandlingInR/
I think something like this should work: xml <- tryCatch(xmlTreeParse(xmlTxt, useInternal=TRUE), error=function(err) xmlMalFormed()) ----- Original Message ---- From: ppatel3026 <[EMAIL PROTECTED]> To: r-help@r-project.org Sent: Tuesday, June 17, 2008 2:15:43 PM Subject: [R] try catch block How can I use the try catch block such that if this statement fails xml <- xmlTreeParse(xmlTxt, useInternal=TRUE) then this statement is executed xml <- xmlMalFormed() ? This code does not work but assuming its somewhere along these lines: tryCatch(xml <- xmlTreeParse(xmlTxt, useInternal=TRUE), xml <- xmlMalFormed(f1)) -- View this message in context: http://www.nabble.com/try-catch-block-tp17938467p17938467.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org 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@r-project.org 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.
