apollo_insertScaling function

Scales variables inside a function

It changes the syntax of the function by replacing variable names for their scaled form, e.g. x --> x*apollo_inputs$apollo_scale[["x"]]. In assignments, it only scales the right side of the assignment.

apollo_insertScaling(e, sca)

Arguments

• e: Function, expression, call or symbol to alter.
• sca: Named numeric vector with the scales. The names in these vectors determine which variables should be scaled.

Returns

A function, expression, call or symbol with the corresponding variables scaled.
