## Why not package bear? [R for BE/BA]

Thanks helmut, tried the above code and it is matching with the SAS Results.

» Always a good idea to learn the basics of R.

Ya, You are right and working on it to improve my r basics, but however i have searched for many websites to learn the Bio equivalence packages, but not able to find how can i implement it.

» However, consider Yung-jin’s nice package bear.

Yes, i heard about the BEAR Package, and also installed the same package. when i am trying to use the package, it showing the warning message "package ‘bear’ was built under R version 3.5.2". i dont know how to clear this error and how can i call the package for using in the Bio equivalence study. Any help in this regards is highly appreciated.

Also want to know about the PKNCA package on R. How can i use the package. Does the package covers all the parameters as that of the WinNonlin. Does it gives the same result as that in the Phoenix WinNonlin Software
