Question

可能重复：
Cannot install R-forge package using install.packages

有没有人让latest version of TTR from R-forge在R 2.13上工作？我无法在我的Mac或PC上安装它，即使我尝试从源代码编译。

/ edit：当我尝试从R命令行安装时，这是我得到的确切错误。

install.packages("TTR", repos="http://R-Forge.R-project.org")
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
  package ‘TTR’ is not available (for R version 2.13.0)

是的，确定：

edd@max:~/svn/ttr$ svn up
At revision 107.
edd@max:~/svn/ttr$ R CMD INSTALL .

Answer 2

新闻称它现在在CRAN上。我的Mac上有0.20-2，安装程序报告说这是最新的。加载似乎成功，并且运行一些示例没有错误。

重新制作r-forge版本20-3我得到了这个：

install.packages（“TTR”，repos =“http://R-Forge.R-project.org”）警告信息：在getDependencies（pkgs，dependencies，available，lib）中：包'TTR'不可用（对于R版本2.13.0 beta）

R版本2.13.0 beta（2011-04-04 r55296）（不是最新版本）

让TTR在R 2.13上工作？
