Hi Abs,
This is because the class is "f", not c("f", "function") in your second
example. S3 method dispatch is doing what you (unintentionally, I presume)
asked it to do.
The S3 method which allows head to take functions is utils:::head.function.
S3 can only be expected to understand inheritance
(Using R 3.5.3).
I found bugs in head() and tail().
The following works:
> f = function () 1
> head (f)
1 function ()
2 1
However, the following does not:
> class (f) = "f"
> head (f)
Error in x[seq_len(n)] : object of type 'closure' is not subsettable

There's a similar problem with inherits().
On R 3.5.3:
> f = function () 1
> class (f) = "f"
> is.function (f)
[1] TRUE
> inherits (f, "function")
[1] FALSE
I didn't check what happens with:
> class (f) = c ("f", "function")

Hi Sam,
Is your PATH set on your user environment variables or on the system?
Did you try to remove the entry for R-3.5.2 ?
I have tested with a standard install, and I can't reproduce your error. I
have the exact same path in my system PATH environment variable for 3.5.3,
and nothing for other v
Hi all,
I am noticing some strange behaviour so I am bringing to this list. In the
past when I have submitted bugs to bugzilla, I have come here first for
confirmation/advice. Hopefully this is appropriate.
Upgrading from R 3.5.2 to R 3.5.3 seems to have elicited some strange
behaviour on my Wind
This commit adds a function parameter to readtable. The function is called
for every column.
The goal is to allow specific (non-standard) type conversions depending on the
input.
When the parameter is not given, or the function returns NULL, the legacy
default applies.
The colClasses parameter st
