Is it possible to get R to output the value of an expression, that is being
calculated within a function? I've attached a very simple example but for more
complicated ones would like to be able to debug by seeing what the value of
specific expressions are each time it cycles through a loop that executes the
expression. I'm relatively new to this so there may be much simpler more
elegant ways to do it.
For example, is there a command I can put within the function "funct01" that
will output the value of z1 to the screen?
Thanks
Jim
==================================
## Practice file to try out evaluations
y <- 5
(x <- y^2)
funct01 <- function (x,y) {
z1 <- x + y
z2 <- x * y
z3 <- x^y
results <- data.frame (z1=z1, z2=z2, z3=z3)
return(results)
}
funct01(7,9)
