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(所以我的知识可能相当有限)。我得到一个错误,防止我的包被安装后,它已被建立它不是一个Win32应用程序...这个R软件包为什么不能安装,我该如何解决?
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)

[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
要初步建成了包,我运行此:
library(devtools)
library(roxygen2)
setwd("C:/panterasBox")
create("myPack")
setwd("C:/panterasBox/myPack")
dir.create("C:/panterasBox/myPack/src")
这是Fortran代码,在/src
文件保存为myFunc.f:
subroutine myFunc(x)
implicit none
real(8) x
x = x + 2
return
end
我用它来调用它的R包装(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,创建文档和安装包,运行此:
> document()

我也试图建立并通过使用R CMD build myPack
,然后R CMD check myPack_*tar.gz
命令行检查包装。我得到的唯一的错误是关于我的LaTeX软件包。
感谢您阅读本文,我感谢您提供的任何帮助。
声明:我之前曾问过这个问题,但我想以“最小的方式”再次提问。
快速浏览,我看到你至少应该做'回报(MYCALL $ X)'(而非目前'回报(的MyCall $ X)')。 –
@ JoshO'Brien谢谢。这对我来说是蛮横的。它没有解决问题,但我解决了这个问题。 – panterasBox
你确定你没有混合i386和x86_64文件吗? '无法加载共享对象'C:/Users/pantera/Documents/R/R-3.2.2/library/myPack/libs/i386/mypack.dll':'包含'i386',但是您已经编译为64位。 –
