r - Blotter R 与 XTS 包一起使用

Question

大家好，有没有人注意到，自 9 月 15 日上次更新以来，无法再从 Forge 下载 blogger R 包。

这是一个小故障还是整个软件包已被删除并且不再是开源的一部分？

Answer 1

它仍然存在并且可以下载，但未安装：

....
* installing *source* package ‘FinancialInstrument’ ...
** R
** data
** demo
** preparing package for lazy loading
Loading required package: Defaults
Loading required package: xts
Loading required package: zoo
Loading required package: TTR
Error : object ‘as.Date’ is not exported by 'namespace:zoo'

* removing ‘/home/gavin/R/libs/FinancialInstrument’

* removing ‘/home/gavin/R/libs/blotter’

The downloaded packages are in
    ‘/tmp/RtmpKtHp8W/downloaded_packages’
Warning messages:

构建一个包（ FinancialInstrument ）似乎存在问题，它是吸墨纸的依赖项，因此在 R-Forge 构建系统中可能无法正常工作。通过 R-Forge 站点联系维护人员以获得进一步的帮助。

Answer 2

您需要安装 FinancialInstrument。如果您已经安装了 FinancialInstrument，则需要对其进行更新，因为现在吸墨纸依赖于 FinancialInstrument(>=0.6.3)。
