Hi All,
I need to give my R code to my client to use. I would like to protect the
logic/algorithms that have been coded in R. This means that I would not
like anyone to be able to read the code.
I am searching for ways to protect R code. I would like to create a .exe
kind of file which could be executed without using R or requiring to
install R. I would not like the R code to be loaded in R. This is so
because, after R loads a function, if you type the function name on the
command prompt, you can see the complete code. I would not like to give
this type of access to the R code.
I explored the option of creating .bat file (using command: R CMD BAT) and
byte code (using command: compile). These are not useful since they open
R, load these functions and then the R code is visible.
Is there any other way to protect the R code which would help me package
all my files/source files and give me an executable file which would be
run without opening R? Another problem is that R is freely downloadable.
Is it somehow possible to protect the code from being loaded in R and
being seen.
Hmmmm, R is open source software under the GPL (which is infective) and
designed as such. Good luck it is almost impossible to hide the source
code in R. And people who tried to generate C based binary packages
found those can only be used under a small subset of platforms with few
versions of R.
Since R is distributed under the GPL: When you write code and make it
available to others, you should be aware of this fact that you may have
to distribute the sources under GPL as well - under some circumstances
your lawyer can explain much better than I.
Thanks
