I am writing a function that i want to include in a user-defined package (MYPACKAGE). The function is a follows:

readSchedule <- function(FILE){
    WB = loadWorkbook(FILE)
    WS= readWorksheet(WB, sheet = 'Sheet1',header = TRUE)
    return(WS)
}

where FILE is the name of the Excel file i want to read. When writing this function, I want it to import XLConnect, since that is the package it uses. I placed header code defining the function:

@param FILE Excel file
@return Excel data
@export
@import XLConnect

I have also added import(XLConnect) to the NAMESPACE and the DESCRIPTION file of MYPACKAGE. The package builds fine (or at least at first cut it appears to build OK) but when i run "Check Package" it fails and gives me the following error:

* installing *source* package 'MYPACKAGE' ...
** R
** preparing package for lazy loading
** help
*** installing help indices
** building package indices
** testing if installed package can be loaded
*** arch - i386
Error : .onLoad failed in loadNamespace() for 'rJava', details:

  error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.
Error: loading failed
Execution halted
*** arch - x64
ERROR: loading failed for 'i386'

I have the correct version of Java and can load rJava just fine. i've tried importing rJava (similar to XLConnect) but i get the same error. Below is my sessionInfo:

It looks like you are building your package on a Windows 64-bit machine with a 64-bit version of Java installed. When checking your package using R CMD check, R by default also attempts to check your package on other sub-architectures (i386, 32-bit) which in your case would in addition require a 32-bit installation of Java.

If you want to check your package also for i386 you may just additionally install Java 32-bit. The other option is to pass the option --no-multiarch to your R CMD check call, e.g. R CMD check --no-multiarch MYPACKAGE.
