Я работаю r-studio version 1.1.463 на macos Yosemite Version 10.10.5. Мой ноутбук с начала 2015 года. Всякий раз, когда я пытаюсь установить какие-либо пакеты в R-Studio, он выдает мне следующее сообщение об ошибке:
Извиняюсь за то, что я полный n00b, но я не уверен, означает ли это, что пакеты получили скачал. Если они есть, где я могу их найти и что мне нужно сделать, чтобы они были установлены в R-Studio? У меня нет компилятора C, и я не уверен, что он мне нужен.
