Dear all,
A recent bug fix for data.table was for non-ascii characters in column
names and grouping by those column. So, the package's test file now
includes non-ascii characters to test that bug fix :
# Test non ascii characters when passed as character by, #2134
x = rep(LETTERS[1:2], 3)
y = rep(1:3, each=2)
DT = data.table(ÅR=x, foo=y)
test(708, names(DT[, mean(foo), by="ÅR"]), c("ÅR","V1"))
test(709, DT[, mean(foo), by="ÅR"], DT[, mean(foo), by=ÅR])
DT = data.table(FÅR=x, foo=y)
test(710, names(DT[, mean(foo), by="FÅR"]), c("FÅR","V1"))
DT = data.table(ÆØÅ=x, foo=y)
test(711, DT[, mean(foo), by="ÆØÅ"], data.table(ÆØÅ=c("A","B"), V1=2))
test(712, DT[, mean(foo), by=ÆØÅ], data.table(ÆØÅ=c("A","B"), V1=2))
This passes R CMD check on Linux, Windows and Mac on R-Forge, but not on
Mac on CRAN because Prof Ripley advises that uses the C locale.
It works on Windows because data.table does this first :
oldenc = options(encoding="UTF-8")[[1L]]
sys.source("tests.R") # the file that includes the tests above
options(encoding=oldenc)
If I change it to the following, will it work on CRAN's Mac, and is this
ok/correct? Since it passes on R-Forge's Mac, I can't think how else to
test this.
oldlocale = Sys.getlocale("LC_CTYPE")
if (oldlocale=="C") Sys.setlocale("LC_CTYPE","en_GB.UTF-8")
oldenc = options(encoding="UTF-8")[[1L]]
sys.source("tests.R") # the file that includes the tests above
options(encoding=oldenc)
Sys.setlocalte("LC_CTYPE",oldlocale)
Many thanks,
Matthew
