nice! Some quick feedback (I did not do too much testing): ANOVA: - The "Data" varslot could be made to default to the current data.frame (if one is opened for editing). Like in the "Sort Data" plugin. Simply connect the special "current_object" property to the "available" property of var.data. - For purely between designs, is it really necessary to specify a subject id? Could this be made to default to rownames (x) or something similar? - Not sure, whether saving the results to the workspace by default is a good idea. On any subsequent run, users will have to check the "overwrite" option (or turn off saving). - I'm not entirely sure, how this would work out, but have you tried swapping the "Model"-options and those options which are currently on the first tab? After all, you will always want to specify a model, but for the other options, it's often ok to leave the defaults. Pairwise t-Test: - The R default for p.value correction is "holm". Perhaps the plugin should use the same default? - Ideally, the plugin would support both wide (separate variables) and long (outcome + group variable) format. Perhaps a generic conversion facility would be a good candidate for an embeddable plugin, since this would come in handy in many places. (See box plot for an example of a plugin that already supports both formats). General: - All your rk.header()s start at level=2. For consistency, they should start at level=1, with the lower levels reserved for subsections. If you don't like the looks of that, fix pages/rkward_output.css, and / or rk.header(). Having consistent levels of headings will become particularly important, once we add table of contents / navigation features to the output. Regards Thomas
