Loading the library crashes RStudio.

A quick fix in the setLanguage.R file solved the issue, but I cannot push it. File content is copied here below:

Management of locales and message translation using msgcat

' Change or get the language used in R and Tcl/Tk, strings translation in Tcl

'

' The function changes dynamically the language used by both R (messages only)

' and Tcl/Tk, retrieves its current value, and manage string translation in

' Tcl.

'

' @param lang An identification for the targeted language, for instance, \"en\"

' for English, \"en_US\" for american English, \"fr\" for French, \"de\" for

' German, \"it\" for Italian, etc. Facultative argument for [tclmclocale()].

' @param msg A single character string with the message to translate.

' @param translation The corresponding version in `lang`. Substitutions markers

' like \%s for strings, or \%d for numbers are allowed (same syntax as

' [base::gettextf()]). These translations are added in the Tcl catalog in the

' main domain, i.e., you don't need to give a domain name with [tclmc()] to

' retrieve the translation.

' @param fmt A single character vector of format string.

' @param ... Values to be passed into \code{fmt} for the substitution.

' @param domain The 'domain", i;e., Tcl namespace where the translation is

' defined. Use `NULL` (the default) or `""` for the main domain where

' translations using [tclmcset()] are stored.

'

' @return

' [setLanguage()] returns `TRUE` if language was successfully changed in

' Tcl/Tk, `FALSE` otherwise. [getLanguage()] returns a string with current

' language in use for R, or an empty string if it cannot determinate which is

' the language currently used, and a `tcl.language` attribute with the

' different catalogs that are used in priority order (ending with `""` for no

' translation, i.e., Tcl translations do not return an error, but the initial

' string if the item is not found in the catalog).

' [tclmclocale()] allows to change and get language for Tcl only, without

' changing anything for R.

'

' The two functions [tclmcset()] and [tclmc()] allow to record and retrieve the

' translation of strings in the main R domain. Moreover, [tclmc()] also allows

' to retrieve translations of Tcl strings in other Tcl namespaces (a.k.a.,

' domains), see the examples.

'

' @note You need the msgcat Tcl package to use this (but it is provided with

' all recent distributions of Tcl/Tk by default).
