Dear list,
The following behavior in base R is unexpected to me:
a <- as.hexmode("99ac")
b <- as.hexmode("9ce5")
v <- c(a,b)
v
#> [1] 39340 40165
class(v)
#> [1] "integer"
Is there a good reason why v should not be of class "hexmode"?
I can see that this is exactly as documented. The help for `c()` only says that
the arguments are coerced to a common type (which is integer anyway) and that
all attributes except names are removed. On the other hand, it says further
down that "c methods other than the default are not required to remove
attributes (and they will almost certainly preserve a class attribute)".
So couldn't (or even shouldn't) there be a c.hexmode that keeps the class
attribute?
Best regards,
Dominic
