[R] Problem building binary data into library file

[Steven Yen]

I build binary data files into a library by placing the .rda files at the proper \data sub-folder before building the library with the following procedure:
1. File -> Open project
2. Build -> Build binary packages.
This has worked up to 3 .rda files.

Now, I add another .rda file to the folder. I received a very strange, seemingly unrelated warning message that says:

Warning: object '.Random.seed' is created by more than one data call

The weird thing about this is, repeating the procedure, I sometime can access the data file from the library (i.e., by data(filename)), other time I cannot access the data file. The data file is big but not so big (571 KB).

Any clues? Why am I getting that warning message?
