For the same reason, handling false positive in CRAN checks, there are
other places that could be improved.
Like "size of tarball" NOTE.
If one could control this size with an environment variable. Similarly
to the proposal made by Jim. It would be useful as well.

Sergei,
the main problem that I was pointing out is is that there is no way you can
introduce the new syntax without breaking the old one. The expression is
evaluated to obtain a function, so by definition using anything that results in
a valid expression for your syntax will break. E.g., using
Thanks Henrik,
Probably, it will be the solution I'll retain.
Best,
Serguei.

Hi,
I notice that read.spss store variables' labels into df's attributes
as $variable.labels, while write.dta read df's attribute $var.labels as
variable labels. This becomes a problem when I try to convert a bulk of
SPSS's por files into STATA's dta format using these commands. The data

Such a helper already exists in magrittr, which allows you to compose anonymous
functions like so:
library(magrittr)
sapply(1:10,. %>% add(4))
That said, I'm all for this being able to be shortened to sapply(1:10,add(.)),
but that would require language support, as Serguei asks for. Languages s
I'm sure this exists elsewhere, but, as a trade-off, could you achieve
what you want with a separate helper function F(expr) that constructs
the function you want to pass to [lsv]apply()? Something that would
allow you to write:
sapply(split(mtcars, mtcars$cyl), F(summary(lm(mpg ~ wt,.))$r.square
This syntax is already implemented in the {purrr} package, more or
less -- you need to add a tilde before your function call for it to
work exactly as written:
purrr::map_dbl(split(mtcars, mtcars$cyl), ~ summary(lm(wt ~ mpg, .))$r.squared)
is equivalent to
sapply(split(mtcars, mtcars$cyl), funct
I'd second Jim's feature request - it would be useful to be able to
disable this in CI and elsewhere.The concept of using an "unusual"
version component such as a very large number does a nice job of
indicating "unusual" and serves as a blocker for submitting
work-in-progress to CRAN by mistake
Thanks Bill,
Clearly, my first proposition for wsapply() is quick and dirty one.
However, if "." becomes a reserved variable with this new syntax,
wsapply() can be fixed (at least for your example and alike) as:
wsapply=function(l, fun, ...) {
.=substitute(fun)
if (is.name(.) || is.cal
Simon,
Thanks for replying. In what follows I won't try to argue (I understood
that you find this a bad idea) but I would like to make clearer some of
your point for me (and may be for others).

Passing in a function passes not only an argument list but also an
environment from which to get free variables. Since your function doesn't
pay attention to the environment you get things like the following.
> wsapply(list(1,2:3), paste(., ":", deparse(s)))
[[1]]
[1] "1 : paste(., \":\", deparse

Or you use a fourth component to signal a development version as Rcpp has
done for years (and, IIRC, for longer than devtools et al used '9000').
There is no functional difference between 1.2.3.1 and 1.2.3.9000. They are
both larger than 1.2.3 (in the package_version() sense) and signal an

Hi,
I would like to make a suggestion for a small syntactic modification of
FUN argument in the family of functions [lsv]apply(). The idea is to
allow one-liner expressions without typing "function(item) {...}" to
surround them. The argument to the anonymous function is simply referred
as "."
