In byu-transpolab/apollo-byu: Tools for Choice Model Estimation and Application

Description Usage Arguments Details Value

Expands loops replacing the index by its value. It also evaluates paste and paste0, and removes get.

1	apollo_expandLoop(f, defs = NULL, env = NULL)

`f`	A function or an expression
`defs`	A named list of expressions to replace inside the loop. NULL by default.
`env`	An environment with additional values to use in the loop expansion

For example, the expression for(j in 1:3) V[[paste0('alt',j)]] = b1*get(paste0('x',j)) + b2*X[,j] would be expanded into V[[alt1]] = b1*x1 + b2*X[,1] V[[alt2]] = b1*x2 + b2*X[,2] V[[alt3]] = b1*x3 + b2*X[,3]

A function or an expression (same type as input f)
