[Gretl-devel] ui-maker news

For authors of function packages: there are new restrictions that can be added to the ui-maker function for a package, to ensure for a given series parameter (a) that the argument is a 0/1 dummy variable or (b) that it is discrete. Here's an example, assuming that the bundle returned by the ui-maker is called ret; that the series y must be binary; and that the series z must be discrete: ret.y = _(binary=1) ret.z = _(discrete=1) Note that the criterion in the "discrete" case is a bit more liberal than the built-in isdiscrete() function. More details can be found in the current version of pkgbook.pdf (or pkgbook-a4.pdf). Allin
