How do you evaluate variable as option name in R?

Question

I have two variables, as follows:

tokenName = "myToken"
tokenResult = "myResult"

I'd like to set options() where I evaluate the variable tokenName and set that option as myResult .

Essentially I want the equivalent of options(myToken = tokenResult) , but using the variable tokenName .

I tried options(eval(tokenName) = tokenResult) but to no avail. Does anyone have any ideas?

Answer 1

We can use setNames

do.call(options, as.list(setNames(tokenResult, tokenName)))

-checking

options()[[tokenName]]
#[1] "myResult"
