To cite the mvp package in publications please use @hankin2022_mvp. This short markdown document creates variables a, b, $\ldots$, z which are single-symbol mvp objects. Letters c, q, and t present particular problems as they have distinct meanings in R, which is why one needs to use data() in a session.

for(letter in letters){
  eval(parse(text=paste(letter, ' <- as.mvp("',letter, '")')))
}

With these variables we can do all sorts of slick calculations:

(a+b)*(a-b)
a^3 + b^3 + c^3 - 3*a*b*c == (a+b+c)*(a^2+b^2+c^2-a*b-a*c-b*c)
