similar to: Moving from Splus to R - advice/opinions request from amanagement perspective

Hi, I've looked through the archives and seen several posts discussing technical differences between R and S(plus). It appears to me that R can likely functionally replace Splus for my situation, but I'm more interested in looking at the risks and benefits of moving from Splus to R from a (project) management point of view. Background (a bit wordy, I'm afraid): -

In the past few years we have been working on making it possible to use packages in both R and Spotfire S+ (previously officially called S-PLUS). One problem was that certain lines in the DESCRIPTION file of a package needed to be specific to R or Spotfire S+. E.g., if your package used the xyplot() function then the package would depend upon lattice in R and trellis in Spotfire S+, or a package

We've been working on making it easier to write packages that work in both R and Splus. One issue is that R and Splus use different internal representations of integers and this makes a difference on their 64-bit versions: R uses ints (32 bits on 32-bit and 64-bit versions of R) and Splus uses longs (32 bits on 32-bit Splus and 64 bits on 64-bit Splus). The obvious ways to deal with the

Hello there, I spent all day yesterday trying to get a small data set from Splus into R, no luck! Both, Splus and R, are run on a 64-bit RedHat Linux machine, the versions of the softwares are 64-bit and are as what follows: Splus: TIBCO Software Inc. Confidential Information Copyright (c) 1988-2008 TIBCO Software Inc. ALL RIGHTS RESERVED. TIBCO Spotfire S+ Version 8.1.1 for Linux 2.6.9-34.EL,

Hi All, I just used "dump" on Splus to transfer a pile of survival objects from Splus 3.4 on Solaris 7 to R 0.63.3 on Intel. The only trick is that survival objects contain an element holding the original call that generated the object. When Splus writes these out, it doesn't mark them in any way, so when R tries to read them in, it ends up trying to reevaluate the call. Not

You need to tell us what compare() in S-PLUS does; i.e., what does it take as input and what does it output. Presumably the information would be in the help page for compare(). Telling us what the function looks like in S-PLUS is of no use, since most likely the code cannot be used in R without violating S-PLUS copyright and/or license. Even if that wasn't an obstacle, the fact that it

Hello Everyone,   I’m a SAS user who has recently become interested in sequential clinical trials designs. I’ve discovered that the SAS based approaches for these designs are either too costly or are “experimental.” So now I’m looking for alternative software. Two programs that seem promising are SPLUS Seqtrial and R.   I recently obtained a 30 day trial for the SPLUS Seqtrial add-on and have

Good afternoon, Hope you all have a wonderful day. I am glad to be here. Hope you could help me with the following errors that i have been trying to figure it all out since last week. I am using Splus from Insightful, and as i read, R and Splus are very similar. So hope you could help me. I have been continously received these error messages after i ran my small program for couple of

Hello, I learnt there's an advanced R/Splus course in Boston this january. Anyone got the announcement? please kindly forward it to me. Best, Eugene

Hi all, Thanks for the wonderful forum with all the valuable help and comments here. I have been a splus user for the past 7 to 8 years and now crossing the mind of changing over to R. Have been doing a lot of reading and one of the main reasons is being an open source and the wonderful things that comes with that. My question is though, is it possible to export any of the function or librarys

Dear R makers and users. I summarize answers to my question. Thanks for your help. The conclusion seems to be that, in terms of performance with large datasets, Matlab=Octave > R > Splus5.1 > Splus5.0 but Matlab/Octave lack many of the stat functions of R/S, and, R does not have as many time-series functions as S+ (but see last message to r-announce by adrian.trapletti at
