[Rd] Typo in ?image
In ?image (src/library/graphics/man/image.Rd), the text fragment "will show though" should probably be "will show through". -- Mikko Korpela Department of Geosciences and Geography University of Helsinki __ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel

[Rd] as.character.factor and S4 object containing factor
Do I mess up something or is this a bug? If I define an S4 object
that contains "factor", all the tests indicate that it is a factor but
as.character.factor() complains of it being a non-factor...

Object of class "Foo"

[1] TRUE

Error in as.character.factor(a) : attempting to coerce non-factor

Error in as.character.factor(x) : attempting to coerce non-factor
In addition: Warning message:
In print.factor(a) :
Setting class(x) to NULL; result will no longer be an S4 object
This means I cannot use ordinary print/summary methods...

Re: [Rd] as.character.factor and S4 object containing factor
The issue with as.character.factor() was reported and fixed recently.
https://bugs.r-project.org/bugzilla/show_bug.cgi?id=17141
The warning emitted from print.factor() is interesting. I'm not sure
why we are setting the class to NULL there. Could just create a new
character vector instead. Will look into it later.
