    1. This table or related slice is empty.
    1. COThis was my thought, too. I'd also add thinking about controlling what loads when R is started. If you want to be efficient, control the profile so that only the required libraries are loaded at start up, including, in this case, ggplot2.

    2. COI don't see how a parametrized list would be any more convenient than a formula. If you're constructing the argument list by name, it is no more difficult to simply construct the formula expression itself. If you're utilizing a list of elements to pass as an argument (e.g., through do.call), then this is no more difficult than using formula functions like model.matrix and model.frame, among others, to parse a formula given a data set. In either case, you still need to automate your selection of parameters, either by name or by reference to entities (or some manipulation thereof). Make sense?

      1. POWhich classification packages in R have a non-formula interface (e.g., f(x,y) instead of f(y ~ ., data))?

    3. COI'm thinking rcom might provide some COM ways to interact with PHP, but there are probably more direct ways to get it done. It would be an interesting development, but the security issues are great. You would really have to take a bottom-up approach in making sure only a very select set of R operations are permissible, and you better make sure a creative hacker couldn't use those permitted to do system harm! I'm thinking from a web PHP interface, of course.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
