Re: $A$ vs S-Plus

From: "Pravin Jadhav" pravinj@gmail.com Subject: Re: [NMusers] $A$ vs S-Plus Date: Wed, December 8, 2004 4:55 pm Sam and others, R has nlmeODE package developed by Christoffer Tornoe that allows one to write differential equations and tie-up with NLME. However, as I understand NLME in R has not been updated for long time compared to NLME in S-Plus (supported by Insightful). Joga and his group is developing a website that will have various kinds of NONMEM codes as well as R codes(to the extent possible) used in PK -PD modeling. About the other discussion, choice of softwares will differ between users. I agree that S-Plus is limited by the memory requirement but I hardly had a problem. There are ways to make codes more efficient. Also, I find S-Plus very flexible for running simple models because all the traditional diagnostic plots and random effects versus covariates plots etc. can be created by ONE line code. my 2cents.
