Dear Colleague: I am glad to hear from you. I was going to contact you and ask if you have notes on the steps involved on how you implemented LSODA. I will gladly take the project on. In addition to dassl, I want to implement ODESSA also. In other words, my project is a "suite" of ode solvers for R. The application of these solvers will be to the study of the distribution of radioisotopes in living systems in diseases such as heart failure, diabetes, aging and high blood pressure. I have been toying with the latest g77. I find that it does not compile "out of the box" fortran IVP solver codes (ACM transactions ode solver codes). However, the COMPAQ Visual Fortran (cvf) 6.6B compiles the object code without any errors. I plan to work with Windows XP and 2000, cvf, and the latest R. I found that Prof. Ripley's S programming book and the BLUE book are very helpful. I have alreadychecked the r-archives and it has not been helpful. So, any notes on the procedure will be much appreciated. Kind Regards, Oscar A. Linares, MD, PhD Molecular Medicine Unit The University of Michigan Geriatrics Center [[alternate HTML version deleted]]
