Dear useRs, I'm still trying to learn tidyverse syntax.
I would like to select() columns based on their positions/indices, but I cannot find a way to do that (I've seen a lot about doing that for rows, but I could not find anything for columns). I thought it would be obvious, but I cannot find it. Basically, I am looking for something like: mydata %>% select( vector_of_indices ) I know that the pipe is useless here, but there are more steps in my real code. The helper num_range() works only when headers contains the positions (e.g. "x1, x2..."). Of course, it's easy using "[", but I expected it would be possible with select() as well; it would make the code more readable than: mydata %>% .[ vector_of_indices ] Thank you for your help.
