Subject: [R] negatively skewed data; reflecting
This problem may be very easy, but I can't think of how to do it. I have
constructed histograms of various variables in my dataset. Some of them are
negatively skewed, and hence need data transformations applied. I know that
you first need to reflect the negatively skewed data and then apply another
transformation such as log, square root etc to bring it towards normailty.
How is it that I reflect data in R? I'm sorry if this seems a very simple
task, I think it involves going back to Maths GCSE and relearning
reflection, rotation, translation etc! I have searched the internet, but
cannot come up with anything useful on how to reflect data.

I am grateful for any help regarding this matter, it is just a very small
part of my analysis and doesn't seem worth agonising hours over. I will
probably kick myself when someone tells me the answer!
Thank you very much,
