Hello!
I work with:
R : Copyright 2006, The R Foundation for
Statistical Computing
Version 2.3.1 (2006-06-01)
On Windows XP Professional (Version 2002) SP2
I think there is a bug in the conditional
execution if (expr1) {expr2} else {expr3}
If I try:
"if (expr1) expr2 else expr3"
it works well but when I put the expression expr2
and expr3 between {} I receive an error message
like this one:
"Erreur dans parse(file, n = -1, NULL, "?") :
erreur de syntaxe ? la ligne
4: }
5: else"
...which translated in english gives:
"Error in parse(file, n = -1, NULL, "?") : syntax
error at the line
4: }
5: else"
Maybe, there is something I don't understand. I
should be very grateful if you would help me to
solve this issue.
Best regards,
Xavier

You need the } on the same line as the else if (expr1){ expr2 } else { expr3 } as otherwise R doesn't know there is going to be an 'else'. -thomas> "Erreur dans parse(file, n = -1, NULL, "?") : > erreur de syntaxe ? la ligne > 4: } > 5: else" > > ...which translated in english gives: > > "Error in parse(file, n = -1, NULL, "?") : syntax > error at the line > 4: } > 5: else" > > Maybe, there is something I don't understand.
