Probably the best thing to do is create an environment within the package that you can assign to and read from.
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).
