从Github安装R-Package IKTrading-错误消息

Question

I allow myself to post this help request as my attempts to download the R package "IKTrading" from Github repeteadly failed. I used both R V. 3.1.3. and R V.3.2.1.with identical results.

My computer runs R on Windows 7, 64bit version. Here is the session status:

R version 3.1.3 (2015-03-09) -- "Smooth Sidewalk" Copyright (C) 2015
The R Foundation for Statistical Computing Platform:
x86_64-w64-mingw32/x64 (64-bit)

Standard recommended solutions I found on the internet did not work in my case, such as: - Running R as administrator (done) - Making sure that that Rtools is already installed (done) - Scrupulously respecting the order of execution of different R packages, including more particularly devtools and quantstrat (done all that).

Here is the error message output for further investigation:

Answer 1

This worked for me:

Installing package quantstrat as IKTrading package has dependency on it.

require(devtools)
install.packages("quantstrat", repos = "http://R-Forge.R-project.org")
library(quantstrat) #Load package
install_github("IlyaKipnis/IKTrading")

If this doesn't work, try running RStudio as administrator and run these commands again. Let me know if it works !
