R non è in grado di caricare la previsione del pacchetto a causa dell'errore dello spazio dei nomi

Question

Ho provato a installare tutti i pacchetti dipendenti e ho anche provato un'altra fonte di repository come consigliato in un altro post qui.

versione R 3.2.0 x64

install.packages("fracdiff") 
install.packages("Rcpp") 
install.packages("RcppArmadillo") 
install.packages("colorspace") 
install.packages("forecast", dep=T) 
install.packages("forecast", repos=c("http://cran.rstudio.com"),dep=T) 
library("forecast") 

allora ottengo

Loading required package: zoo 
Attaching package: ‘zoo’ 
The following objects are masked from ‘package:base’: 
as.Date, as.Date.numeric 

Loading required package: timeDate 
Error : .onAttach failed in attachNamespace() for 'forecast', details: 
call: fun(libname, pkgname) 
error: 4 arguments passed to .Internal(nchar) which requires 3 
In addition: Warning message: 
package ‘forecast’ was built under R version 3.2.1 
Error: package or namespace load failed for ‘forecast’

Answer 1

ho cercato di riprodurre. Non ricevo alcun messaggio relativo al tempo di caricamento o all'errore visualizzato. Ricevo un messaggio sul caricamento di pkg: zoo. Il pacchetto carica e annuncia il suo numero di versione. Prova ad aggiornare a R versione 3.2.1, in quanto è lì che è stato introdotto un nuovo argomento per nchar:

new$Text[ grep("nchar", news$Text) ] 

• nchar(x, *) and nzchar(x) gain a new argument keepNA which governs how the result for NAs in x is determined. For the R 3.2.x series, the default remains FALSE which is fully back compatible. From R 3.3.0, the default will change to keepNA = NA and you are advised to consider this for code portability.
