Hi, When building a source package on Linux with 'R CMD build', the files in the resulting tarball don't have the original permissions. The problem is that the packages I want to build include an SQLite data base (an .sqlite file) and, before I run 'R CMD build', I've made this file read-only (chmod 444) because I want this DB to be read-only. Then if I install by running 'R CMD INSTALL' directly on the source directory, everything works as expected (the permissions of the installed .sqlite file are conserved). But if I run 'R CMD build' in order to produce the tarballs (I need to distribute those packages), then, when the user will install them, the SQLite DBs will not be read-only anymore. Is there a way to prevent 'R CMD build' from changing the permissions of the source files? Thanks in advance! Cheers, H
