为什么不安装此R包,我该如何解决?

我想在R包中包含一个Fortran子例程。我一直只使用devtools和roxygen构建包(所以我的知识可能非常有限)。我收到一个错误,阻止我在构建它之后安装它不是Win32应用程序...

我正在使用Rtools 3.3。我的会话信息:

> sessionInfo()
R version 3.2.2 (2015-08-14)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 7 x64 (build 7601) Service Pack 1

locale:
[1] LC_COLLATE=English_United States.1252  LC_CTYPE=English_United States.1252    LC_MONETARY=English_United States.1252
[4] LC_NUMERIC=C                           LC_TIME=English_United States.1252    

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

other attached packages:
[1] roxygen2_5.0.1 devtools_1.9.1

loaded via a namespace (and not attached):
[1] magrittr_1.5  tools_3.2.2   Rcpp_0.12.1   memoise_0.2.1 stringi_1.0-1 stringr_1.0.0 digest_0.6.8 

要初步构建软件包,我运行它:

library(devtools)
library(roxygen2)

setwd("C:/panterasBox")
create("myPack")
setwd("C:/panterasBox/myPack")
dir.create("C:/panterasBox/myPack/src")

这是fortran代码,保存为/src文件中的myFunc.f:

         subroutine myFunc(x)
         implicit none
         real(8) x

         x = x + 2

         return
         end

我用来调用它的R包装器(保存在/R文件中):

#' @title A test
#' @description a test function.
#' @param x this is a number
#' @useDynLib myPack
#' @export
myFunc <- function(x){
  if (!is.loaded('myFunc')) {
    dyn.load("/src/myPack.dll")
  }
  myCall <- NULL
  myCall <- .Fortran("myFunc", x=as.double(x), PACKAGE="myPack")
  return(myCall$x)
}

现在,要创建文档并安装软件包,我运行它:

我还尝试使用R CMD build myPack然后R CMD check myPack_*tar.gz通过命令行构建和检查包。我做的唯一错误是关于我的LaTeX包。

感谢您阅读此内容,感谢您提供的任何帮助。

免责声明:我之前曾问过这个问题,但我想以“最小化的方式”再次提问。

很明显,这是一个架构问题。看起来你的软件包的x64版本(可能是你需要的)已经成功构建,但是x86构建,因此整个任务失败了。请尝试以下方法:

  1. --no-multiarch选项添加到install来电。这将告诉RCmd不要为x86构建,因为你的主拱是x64。
  2. (可能是可选的,但为了方便起见。)将--no-test-load选项添加到install来电。这将告诉RCmd不要通过加载包的成功来判断构建任务的成功。
  3. 使用library('myPack')手动加载包,看看它是否有效。
  4. 总结一下,将您的install来电替换为:

    install('myPack', args=c('--no-multiarch','--no-test-load'))
    library('myPack')

看起来您正在加载dyn.load("/src/myPack.dll")

但在安装过程中它正在寻找:

'C:/Users/pantera/Documents/R/R-3.2.2/library/myPack/libs/i386/mypack.dll'

(即没有资本P)
