Force devtools::install_github to install only 32-bit versions of packages?

Question

Goal: I want to install dssrip package for R 3.6.0 32-bit on Windows 10 Enterprise.

I have both 32- and 64-bit versions of R 3.6.0 installed. In RStudio (1.2.1522), I set the default version to 32-bit then create new project with packrat enable. I included the following lines in the .Rprofile file inside project folder.

#### -- 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")

Installation:

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

Error:

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

I tried using the native R (C:\Program Files\R\R-3.6.0\bin\i386\Rgui.exe) but it did not help either.

Thanks in advance for any pointer!

Update 2: dssrip has been updated to work with 64-bit r and java. You will need a 64-bit compatible version of HEC-DSSVue (e.g., v3.2.3).

Update: I had to uninstall and delete everything and started from scratch to make dssrip work.

Put the following lines in the .Rprofile file:

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

Install all dependencies:

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

Note that to force R to install only 32-bit version, I had to use this syntax instead:

remotes::install_github("eheisman/dssrip",
                         INSTALL_opts = "--no-multiarch")

Answer 2

Have you tried using RStudio -> Tool -> General, then click on "change" button on top that allows you to change the R-Version. A pull-down menu opens where you can select the 32-bit Version and activate it. You will have to restart RStudio to make it happen, though.
