В настоящее время я работаю над пакетом R и сталкиваюсь со следующей проблемой:
A <- function(){
if(nchar(Sys.getenv("API_URL_SEND")) == 0){
warning("No API address for SEND is set, setting .eu address.")
}
}
B <- function(){
if(nchar(Sys.getenv("API_URL_SEND")) == 0){
warning("No API address for SEND is set, setting .eu address.", call. = FALSE)
}
}
Обе функции идентичны, за исключением того, что функция B использовала call. = FALSE, но мои результаты озадачивают для я:
A()
Error: C stack usage 7971540 is too close to the limit
B()
Warning message:
In "\"\"" : No API address for SEND is set, setting .eu address.
Есть идеи?
Заранее спасибо!
