I had the same problem, but the answer from @little_chemist helped me sorting it out. When installing packages from a file in a unix OS (Ubuntu 18.04 for me), the file can not be zipped. You are using:
install.packages("/home/p/Research/14_bivpois-Rcode.zip", repos = NULL, type="source")
I noticed the solution was as simple as unzipping the package. Additionally, unzip all (installation related?) packages inside, as @little_chemist points out. Then use install.packages:
install.packages("/home/p/Research/14_bivpois-Rcode", repos = NULL, type="source")
Hope it helps!
