If it weren't for those pesky kids

It looks like some people don't learn, and are still using T and F, but with the read_csv() function from the readr package this time. Continue your dastardliness and try to overwrite F.

What happens when you set F <- 2?

iris <- read_csv("iris.csv", col_names = F)

答案选项

No difference to using read.csv(). I can still be evil!

Partially foiled. I can no longer use F <- 2 but I can still set it to F <- TRUE.

Completely foiled. No evilness is possible.
