on of the Weibull distribution used in S-PLUS? I am not obtaining the results I expected for a very simple problem. Thanks in advance, Lola. -- This messag
I think you can use the following trick. Convert your numeric vector to character, count the number of digits following the point, if any. and take the maximun of that. a1 <- c(123, 1, 23.00002, 45)
Q: What does the p-value mean in an epidemiological research paper? A: It stands for the Publication value, and has the following meaning: 1 - p-value = probability of getting the paper published in
For those who are interested, you can now download an S-PLUS routine that minimizes an S-PLUS function using the downhill simplex method. The S-PLUS routine calls a C dll which does all the compuati
The dll that I provided does not do a restart. It starts from a starting simplex and loops until it converges. You have to do a restart "manually". Not only does the Simplex method tends to stop at a
Since it was only a few extra pieces of C code to implement a restart at the point of convergence and/or random starts. I have modified my previous dll. The user can now choose for a restart at the
Hi Hong Ooi, To be honest, I don't know if NULL is suported, special IEEE values such as Inf or NA are suported[ page 572 S+Prog Guide]. But you can always do the test in S-PLUS and then pass the tes
Hi All, programming problems of the form: maximize c'x subject to A1 * x <= b1 A2 * x >= b2 A3 * x == b3 x >= 0 It uses a C dll based on Numerical Recipes code. Cheers, Longhow http://194.171.9.6/Lhh
To my knowledge, the C source code is not freely distributable. But a binairy version of the code (In my case a dll) is. -- This message was distributed by s-news@wubios.wustl.edu. To unsubscribe se

Dear Harald, In S-PLUS 2000 it is a little bit easier than in 4.x. One way to find out the GUI code is to use the object explorer (browser in 4.x) and have a folder filtering on MenuItems, a folder f
Hi S-PLUS users, I have many excel files, all excel files have a specific named sheet, say "test". The problem is that this sheet is not always on the same place, sometimes it is the first sheet of t
Hi All, I am looking for an implementation of the incomplete gamma function in S-PLUS. Does anyone have a ready to use function? Longhow Lam -- This message was distributed by s-news@wubios.wustl.edu
