thanks,
I will not submit to CRAN.

I am having trouble going about including the .exe files in my package.
>From the readings I see that the .exe files must be placed in a 'src'
folder. But I don't see how I can access those files in R, without having to specify its path in the R command 'system'. I would like for the user to only have to input a data file, which is then used in the .exe file.

My problem is the following:
Create a function which has two user inputs i.e. datasets: D1.txt and D2.txt I have two '.exe' files i.e. E1.exe and E2.exe

E1 takes in D1 and then outputs a text file say "text"

then E2 takes in D2 and the "text", which outputs the result.

Can this be done (even if it means having two functions) and then assembled in a package, without the user having to specify the path of the .exe files, as well as the "text" that is outputted from running E1?

Any direction as to how I can go about creating a package that would include these '.exe. files? I have only found documentation on calling .C code in R.

Any help is much appreciated
