branch in [ assumes English text

[MichaelChirico]

          Hello

Please take in account that there is at least a line on [.data.table that regexs on error messages assuming english!

(

data.table/R/data.table.R

Line 397 in ebc185e

if (grepl(":=.*defined for use in j.*only", e$message))

)
(

data.table/R/data.table.R

Line 2775 in ebc185e

stopf('Check that is.data.table(DT) == TRUE. Otherwise, :=, `:=`(...) and let(...) are defined for use in j, once only and in particular ways. See help(":=").')

)

That is likely to leave := in i undetected.

PD: I has been working in spanish translations if I have some time I will complete and share. Are there a branch on which commit translations or something?
