Dear all,
My git2rdata package relies on a stable sorting. I've noticed that
some characters get a different position under R-devel under Windows
10. This is why the unit test of my package only fail in this
combination (https://cran.r-project.org/web/checks/check_results_git2rdata.html)
Below is a minimal example to illustrate the problem.
Best regards,
Thierry
data <-
readLines("https://raw.githubusercontent.com/ropensci/git2rdata/master/tests/testthat/test_b_special.R";,
encoding = "UTF-8", n = 15)
eval(parse(text = paste(tail(data, -3), collapse = "")))
ds$a <- enc2utf8(ds$a)
print(ds$a) # input
Sys.setlocale(locale = "C")
print(sort(ds$a)) # sorted
print(order(ds$a)) # order
print(sessionInfo())
# input

To call in the statistician after the experiment is done may be no
more than asking him to perform a post-mortem examination: he may be
able to say what the experiment died of. ~ Sir Ronald Aylmer Fisher
The plural of anecdote is not data. ~ Roger Brinner
The combination of some data and an aching desire for an answer does
not ensure that a reasonable answer can be extracted from a given body
of data. ~ John Tukey
