I've got a function in an internal package where i use the
@import command in the roxygen headers, to specify that I need to import the
mailR package. After documenting and checking in the package, I tried to re-install it - and I'm faced with a strange error.
Error: package or namespace load failed for 'myInternalPackage':
.onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'C:/Users/lakshmank/Documents/R/win-library/3.5/rJava/libs/i386/rJava.dll':
LoadLibrary failure: %1 is not a valid Win32 application.
mailR requires rJava, and the funny thing is - I'm able to install mailR (and rJava) outside of the package development framework, and get all functions within mailR package to work just fine.
Details about my working environment - I'm running
R 3.5.0 (64 bit) and I've installed java, and can confirm that the
rJava.dll exists in both the
i386 as well as
x64 folders in the
rJava installed library. I've also set my
JAVA_HOME and path variable correctly to me java installation of
Can anyone please point me in the direction of why this might be occurring?
I'm currently working around it by removing the
@import command and specifying
mailR:: for all functions and telling anyone who installs the package to also install
mailR which is a bit of a crap way of working. Appreciate that this is a hard problem to communicate and hopefully I've provided relevant details. Would really be grateful if I can get any help to figure out what's going on.
Thanks very much.
