由于名称空间错误，R无法加载包预测

Question

I tried installing all the dependant packages and also tried another repo source as recommended in another post here.

R version 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")

then I get

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:

error: 4 arguments passed to .Internal(nchar) which requires 3
In addition: Warning message:

Answer 1

I tried to reproduce. I get no message about either loading timeDate or the error you see. I do get a message about loading pkg:zoo. The package loads and announces its version number. Try updating to R version 3.2.1, since that is where a new argument to nchar was introduced:

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.
