This is probably an easy one.
In R, can I replace an if condition character (such as >) with a character and execute the if statement with it?
For example, if the if statement is:
ifelse(1 < 2, "T", "F") But I'm getting the > condition character through a variable:
cc <- ">" How would I write:
ifelse(1 < 2, "T", "F") replacing < with cc?
As it is a relational operator in R, we can use match.fun
cc <- "<" ifelse(match.fun(cc)(1, 2), "T", "F") #[1] "T" This ifelse can be simplified but I assume this is just an example and you want to do something more complicated.
You can also get the required output using eval(parse.. but I would not recommend it
ifelse(eval(parse(text = paste(1, cc, 2))), "T", "F") #[1] "T"
