[R-pkg-devel] Including a jar file in a package

[Barbara Lerner]

We are developing a package that makes a call out to a Java program.  We 
have placed a jar file for this program in inst/java and it works 
nicely.  However, when we run R CMD check, it results in a NOTE:

* checking installed package size ... NOTE
   installed size is 11.0Mb
   sub-directories of 1Mb or more:
 java  10.8Mb

Is it likely that CRAN would accept a package that includes a large 
subdirectory like this?  If not, what is the recommended way to do 
this?  The nice thing about our current solution is that the user of our 
package does not need to separately install the Java program and deal 
with Java's classpath.

Thanks for the advice.

It likely depends on the circumstances.  Did you write the Java code in 
the jar file?  If not, does any other CRAN package use the same jar 
file?  It doesn't really make sense for both of you to package it.


Assuming the jar file isn't already on CRAN, and it really is necessary 
for your package, and your package adds something to CRAN, they'll 
probably allow it.  You should include a comment with your submission 
explaining why you need the exception.

Thanks for this advice.  The Java code was developed by our project and 
is not used by any other R packages.
