Hello, Greg: That is one of the solutions I have tried; the problem is that I can't obtain a package in this way, because an glo-internal.R file is generated (glo is the name of the package) and when I try to create the package an error message appears (a parse error).
The content of the glo-internal.R file is the following: .glo.env <- <environment> where .glo.env is the name of the new environment I create in my source code. What am I doing wrong?. Thanks again for your help. Regards.

Somewhere in the source code for the package include a line like: my.env <- new.env() then within any functions defined after that line you can set variables within the environment with code like:  my.env$paramA <- 3 and other functions can then read my.env$paramA. This way you don't need to worry about assign or <<- and all your functions will have access to the same set of variables (but they won't interfere with the users workspace).
