Erreurs d'installation package « prévisions » en version R 3.3.2

Question

Essayer d'installer le paquet « prévisions » en version R 3.3.2 sur Mac OS Sierra comme suit:

install.packages("forecast") 

Obtenir un tas d'erreurs que je ne suis pas comprendre. D'abord, il télécharge tous les paquets de dépendances à partir de http://cloud.r-project.org. Première erreur que je reçois est la suivante:

* installing *source* package ‘quadprog’ ... 
** package ‘quadprog’ successfully unpacked and MD5 sums checked 
** libs 
gfortran -arch x86_64 -fPIC -g -O2 -c aind.f -o aind.o 
make: gfortran: No such file or directory 
make: *** [aind.o] Error 1 
ERROR: compilation failed for package ‘quadprog’ 
* removing ‘/Users/ekorne201/Library/R/3.3/library/quadprog’ 

Il passe ensuite à:

* installing *source* package ‘fracdiff’ ... 
** package ‘fracdiff’ successfully unpacked and MD5 sums checked 

Après quoi, il dit:

ld: warning: directory not found for option '-L/Users/Shared/Jenkins/workspace/External-R-3.3.2/vendor/build/lib' 
ld: warning: directory not found for option '-L/usr/local/lib/gcc/i686-apple-darwin8/4.2.3/x86_64'

make: *** [fracdiff.so] Error 1 
ERROR: compilation failed for package ‘fracdiff’ 
* removing ‘/Users/ekorne201/Library/R/3.3/library/fracdiff’ 

passe par la même chose pour 'lmtest' et ' RcppArmadillo ', après quoi il se termine par:

ERROR: dependencies ‘tseries’, ‘fracdiff’, ‘lmtest’, ‘RcppArmadillo’ are not available for package ‘forecast’ 
    * removing ‘/Users/ekorne201/Library/R/3.3/library/forecast’ 

    The downloaded source packages are in 
     ‘/private/var/folders/8p/54qnlb9x7bj8syz631_d58t92rmkyp/T/Rtmp246ipQ/downloaded_packages’ 
    Warning messages: 
    1: In install.packages("forecast") :

    2: In install.packages("forecast") :

    6: In install.packages("forecast") :

Collé sur la façon de procéder et apprécierait le conseil.

Answer 1

J'ai eu la même erreur. Je l'ai résolu en installant le gfortran. Dans Mac OS, je peux le faire de telle sorte que

brew install gcc 

et R tel que

install.packages("forecast") 

si

> library(forecast); fit <- tbats(UScitiesD); 
> fit 
BATS(0.566, {0,2}, -, -) 

Call: tbats(y = UScitiesD) 

Parameters 
    Lambda: 0.565592 
    Alpha: 0.2166945 
    MA coefficients: -0.130506 -0.511551 

Seed States: 
     [,1] 
[1,] 90.10291 
[2,] 0.00000 
[3,] 0.00000 

Sigma: 27.61468 
AIC: 761.9238 

Comme mentionné dans les commentaires, une autre méthode consiste à l'installer à partir here.
