R is a language specially made to do many things with vectors and matrices and arrays with any reasonable number of dimensions and also has a host of functions that do things like make diagonal matrices, calculate determinants and multiply them in several ways,  invert them, get eigenvalues and

Can one back transform confidence intervals: yes, just like one back transforms other values. Should one back transform confidence intervals: probably not. Even if you applied the log transformation because it fixed problems in the model residuals, it is possible (likely?) that the reason that t
