CAUTION:

The slice_plot() function is not in the stable MosaicCalc package but in a beta. Given the terribly cumbersome compilation of packages in R the best is to use an R base alternaive,

For functions a good one is curve(),

curve(expr = FUNCTION, from = A, to = B)

for instance: fx <- makeFun(x^2 ~ x)

curve(expr = fx, from = -10, to = 10)

makeFun(formula **~ **input)

Input would be the x in f(x) (for instance)
