R programming Does the R language have reflection

Question

I want to do the following:

currentRun = "run123"
dataFrame$currentRun= someVar; 

such that dataFrame$currentRun is equal to dataFrame$run123.
I want to know if R supports reflective programming. And if it does, how does it work?

Answer 1

The answer to your question is yes. R provides support for reflective programming.

Refer the below example:

foo <- function()1

# without reflection
foo()

# with reflection
get("foo")()
