由于命名空间错误，R 无法加载包预测

Question

我尝试安装所有依赖包，并按照此处另一篇文章中的建议尝试了另一个 repo 源。

R 版本 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")

然后我得到

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

我试图重现。我没有收到有关加载 timeDate 或您看到的错误的消息。我确实收到一条关于加载 pkg:zoo 的消息。该包加载并宣布其版本号。尝试更新到 R 版本 3.2.1，因为这是 nchar 的新参数。介绍:

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.
