Answer 1

Właściwie miałem ten sam problem i po zainstalowaniu RCurl działało.

W celu zainstalowania RCurl w ubuntu, wpisz następujące polecenia w terminalu:

sudo apt-get install libcurl4-openssl-dev 

Następnie w R:

install.packages('RCurl') 

I to jest to!

Answer 2

Jeśli nie możesz zainstalować odpowiedniej wersji libcurl, możesz spróbować użyć funkcji "install_git" zamiast "install_github". Na przykład:

library(devtools) 
install_git("https://github.com/hadley/devtools.git") 

To zadziałało dla mnie.

Answer 3

Niestety, był to pakiet bug w pakiecie r-cran-rcurl w Debianie. Ostatecznie poprawiliśmy go w dystrybucji Debiana: unstable, testing, a ostatnio stable (Jessie 8.2). W Ubuntu jest on ustalony w wily. Przepraszamy za problem i dziękujemy za korzystanie z Debiana lub jego pochodnych!
