Adding a title to a plot
Greetings! I am currently using R x64 4.0.4. I used the box-cox power transformation to create a range of lambdas and log-likelihood values using the equation. b1=boxcox (DV ~ IV1 + IV2, data= newdata) The above codes automatically created a plot with lambdas and log-likelihood values. I want to add a main and subtitle to the plot. Would you please provide me with codes? Any help would be appreciated. Thank you.
