Question

目标：我想在Windows 10企业版上为32位R 3.6.0安装dssrip软件包。

我同时安装了32位和64位版本的R 3.6.0。在RStudio（1.2.1522）中，我将默认版本设置为32位，然后启用packrat创建新项目。我在项目文件夹内的.Rprofile文件中添加了以下几行。

#### -- Packrat Autoloader (version 0.5.0) -- ####
source("packrat/init.R")
#### -- End Packrat Autoloader -- ####

dir.create("packages", recursive = TRUE, showWarnings = FALSE)
.libPaths("./packages")
message("Using library: ", .libPaths()[1])

options(dss_jre_location="C:\\Program Files (x86)\\HEC\\HEC-DSSVue\\java")
Sys.setenv(JAVA_HOME="C:\\Program Files (x86)\\HEC\\HEC-DSSVue\\java")

安装：

install.packages(c("devtools", "rJava", "plyr", "reshape2", "stringr", "tidyverse"),
                 dependencies = TRUE)
library(rJava)
devtools::install_github("eheisman/DSS-Rip",
                         args = "--no-multiarch")

错误：

Java版本：

C:\Program Files (x86)\HEC\HEC-DSSVue\java\bin>java -version
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Client VM (build 16.0-b13, mixed mode)

C:\Program Files (x86)\HEC\HEC-DSSVue\java\bin>java -d64
Unrecognized option: -d64
Could not create the Java virtual machine.

我尝试使用本机R（C:\Program Files\R\R-3.6.0\bin\i386\Rgui.exe），但也无济于事。

在此先感谢任何指针！

您是否尝试过使用RStudio->工具->常规，然后单击顶部的“更改”按钮以允许您更改R版本。将打开一个下拉菜单，您可以在其中选择32位版本并激活它。不过，您必须重新启动RStudio才能实现。

Answer 2

更新：我必须卸载并删除所有内容，并从头开始才能使dssrip正常工作。

在.Rprofile文件中放入以下几行：

options(dss_jre_location="C:\\Program Files (x86)\\HEC\\HEC-DSSVue\\java")
Sys.setenv(JAVA_HOME="C:\\Program Files (x86)\\HEC\\HEC-DSSVue\\java")

安装所有依赖项：

install.packages(c("devtools", "rJava", "data.table", "plyr", "reshape2", "stringr", "tidyverse"),
                 dependencies = TRUE)

请注意，要强制R仅安装32位版本，我必须改用this syntax：

devtools::install_github("eheisman/DSS-Rip",
                         INSTALL_opts = "--no-multiarch")

如何强制R使用32位版本的已安装软件包/库？
