that means that this function 'errorest' is only a S3 generic function
and the effect of it depends on the class of the object it is invoked for.
See for example this manual about method dispatching with S3:
tells you that there is one function defined to work with data frames,
called "errorest.data.frame", and that it is not exported in ipred's
You can get its souce code by typing
tells you in addition that this S3 method is only defined for
data.frames in ipred and not for other object classes, so this is
probably what you are looking for.
