## R-Code for Power in 2×2 Cross-over [🇷 for BE/BA]

Dear Helmut,

I am not an expert in R, and I am trying to adapt your example of power calculation with plot replesentation, but for the calculation of the sample size. My objetive is to plot a graphicala representation with ratio in X axis and sample size in Y axis and setting the CV and power as a fixed value.

Can you or someone help me?

Best regards,
