Hello,in the help of mtext I found "at: If ‘length(at)==0’ (the default), the location will be determined by ‘adj’" But if I use mtext( "hello world", at=NULL) there comes the following error message: Fehler in mtext("hallo Welt", side = 3, adj = NA, at = NULL) : 'at' mit Länge 0 angegeben So the help says it is ok to use at with length(at) == 0 but if I use an at with length(at) == 0 I get an error message. This is a bug, isn't it?
I'd say it's a documentation error: it claims that the default is length 0, but the default is NA, which is length 1. The actual test in the code uses adj when a C equivalent of is.finite(at) is TRUE, so I'll change the docs to match the behaviour, rather than changing the behaviour to match the docs.
