Hi Allan,
When you create an R package you can specify in the DESCRIPTION file
that your package depends on a certain R version and versions of
packages. For example:
[...]
Depends: R (>= 2.7.0), methods, sp (>= 0.9-4), gstat (>= 0.9-58)
Thanks Paul, this is helpful. It doesn't quite do what I want because
support for operators other than `>=` is erratic (the documentation at
[1] seems to suggest that R CMD INSTALL supports any operator while
install.packages() only supports `>=`).
Also I am not sure if it is checked on every package load?
[...]
So distributing code to other people is preferably done using R
packages, which gives you this option.
Agreed in principle (and that is kind of what I am developing), but
sometimes you just want to send a piece of analysis you are working on.
But thanks for the pointer.
Allan
