Description

Evaluate expression from Stan program

Usage

evaluate.expression(stan.expression, ...)

Arguments

stan.expression	String representing Stan expression. All variables must be passed in ... .
...	Any variables present in the parent environment that are needed to evaluate stan.expression

Details

First, all variables specified in ... are loaded into the function environment. Then, all multipliction is replaced by

Value

The result of the Stan expression

Examples

X <- matrix(1:9, nrow = 3)
b <- c(4, 5, 6)

stan.expression <- "(3 + 2) * X * (5 * b)"

# These results match:
evaluate.expression(stan.expression)
print((3 + 2) * X %*% (5 * b))
