I am experimenting with putting vignettes in a vignettes/ directory as suggested in the new R release news. If I understand correctly, it is now suggested that the vignette source (.Stex in my case) should be in the vignettes/ directory and the pdf should be put in the inst/doc/ directory, for the case when it is not being built by R CMD build. I am getting an error (R-2.14.0): (cd inst/doc ;

Is there an easy way to compile a packages's fortran so that it has the information for ddd or gdb to follow the lines of the code? I seem to remember seeing something about this, but I cannot find it in Writing R Extensions. (I see about Valgrind, debugging a segfault, and some other tricks, but what I really want is to follow the fortran logic.) Thanks for any pointers, Paul

Is CRAN having trouble or is it just me? (The web interface is very slow and install.packages() is timing out and giving me "service not available").

I am trying to extend an S3 method to work with an S4 object as well as the S3 objects it works with, but UseMethod does not seem to recognize the S4 class and dispatches to the default method. Is this to be expected or should I be looking for an error in my code? If it is not an error in my code, is there an easy way to do this, or do I have to convert the generic to S4 and then make those

Is it possible in R to call a fortran routine that sets variables in a common block and expect the values to persist when a call is made from R to a second routine that uses the common block? If not (as I suspect), is it possible to use a common block in a group of routines that are used together, for as long the routines do not return to R? Paul

I am trying to understand the missing vs default value for an argument to an S4 method. (I'm not sure if this is a bug or my confusion.) In S3 I can specify a default value for an argument and then both check if the argument was missing in the call, and use it because it takes on the default value. I do not seem to be able to do that in S4 as shown by this simplified example:

Thanks a lot! This was amazing. I'm not sure I see how the conditiion pK1 < pK2 < pK3 is enforced? - it comes from the derivation via generalized Henderson-Hasselbalch but perhaps it is not really necessary. Anyway, the use of Vectorize did the trick! Best wishes Troels Den 06-11-2023 kl. 19:19 skrev Ivan Krylov: > ? Mon, 6 Nov 2023 17:53:49 +0100 > Troels Ring <tring at

I won't send to list, but just to the two of you, as I don't have anything to add at this time. However, I'm wondering if this approach is worth writing up, at least as a vignette or blog post. It does need a shorter example and some explanation of the "why" and some testing perhaps. If there's interest, I'll be happy to join in. And my own posting suggests how the

Dear friends - I have a function for the charge in a fluid (water) buffered with HEPES and otherwise only containing Na and Cl so that [Na] - [Cl] = SID (strong ion difference) goes from -1 mM to 1 mM. With known SID and total HEPES concentration I can calculate accurately the pH if I know 3 pK values for HEPES by finding the single root with uniroot Now, the problem is that there is some

Thanks a lot, Berwin. Unfortunately, pK1 may well be negative and as I understand the literature it may be poorly defined as such, and also seems to be at a boundary, since when lower is set to say rep(-4,3) pK1 is returned as -4 while pK2 and pK3 are undisturbed. Perhaps the point is that pK1 is not carrying any information at the pH around 5. Fair enough, I guess. Only, I believe I need

One way of enforcing such constraints (well, in finite computer arithemtic only "<=" can be enforced) is to rewrite the parameters as: pK1 = exp(theta1) ##

Dear R-helpers ? I have 7 data points that I want to fit a continuous curve to, that should look similar to a sine wave My data points would mark the local minima and maxima respectively. This is what I?ve got so far. And I would keep doing so, but sadly nls() then says that it has reached the maximum number of Iterations? ?

Hi, I apologize for the long message but the problem I encountered can't be stated in a few lines. I am having some problems with the function constrOptim. My goal is to maximize the likelihood of product of K multinomials, each with four catagories under linear constraints on the parameter values. I have found that the function does not work for many data configurations. #The likelihood

Dear list, The task view on optimization does not reference a package for non linear constrained optimization problems. Stefan Theussl told me to look at the Rsolnp package, but unfortunately it is not very clear what method is R ported.
