getVarFormula

Data sets and utilities from Project MOSAIC (<http://www.mosaic-web.org>) used
to teach mathematics, statistics, computation and modeling. Funded by the
NSF, Project MOSAIC is a community of educators working to tie together
aspects of quantitative work that students in science, technology,
engineering and mathematics will need in their professional lives, but
which are usually taught in isolation, if at all.

getVarFormula function

<dl><dt>formula</dt>
<dd>a formula.
The right-hand side selects variables;
the left-hand side, if present, is used to set row names.
A <code>.</code> on the right-hand side
indicates to use all variables not in the LHS.</dd>

<dd>a data frame</dd>
<dt>intercept</dt>
<dd>a logical indicating whether to include the intercept in the
model default: FALSE (no intercept)</dd></dl>
