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
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
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

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")
H
(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

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
