Hi, After some reading and experimentation I found that I cannot solve this problem: 1. I am starting R and check: > system("pwd") /home/woodstock/hoffmacw/R/test > system("echo $HOME") /home/woodstock/hoffmacw > system("echo $R_PROFILE") /home/woodstock/hoffmacw/R > system("ls $R_PROFILE/.Rprofile") /home/woodstock/hoffmacw/R/.Rprofile

Hello, I'd like to ask, how to adjust the space between symbol/line and text in a legend. My legend() is build like that legend(xmax-netzdiff/11, # shouldn't matter here ifelse(ydiff>=0, # ymin-6.5*(netzdiff/11), # ymax-netzdiff/11), # c("stehender Stamm","Windwurf",

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

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

Just reformulate the problem in terms of a function that

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

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

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 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? ?

In one package (pk1) I define some S3 generics and methods. In pk2 I extend the methods to some S4 objects following the description in ?Methods, with setMethod() and setGeneric() either explicit or implicit (tried both). I export the S3 generic and methods from pk1 NAMESPACE and the S4 from pk2. This works, except when I try to use a function defined in pk1, Within the function the S4 method

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

Hi, I am trying to put some graphics I have generated from R on a webpage using dev2bitmap to create a bitmap, .BMP, file. When I look at my notes from 2 or 3 months ago I was successfully able to put the ACTIVE device plot result into a bitmap file using a command such as: dev2bitmap("InsectSpray.BMP") Job done! Now when I try the same command, I get the following: >

I have two tables: Table [packages] id name user_name ------------------- 1 PK1 Ray ------------------- Table [users] id name full_name ------------------- 2 Ray Ray Sun ------------------- My purpose is to find the full name when I find packages.

I have a small table that is used to temporarily queue requests, as such it does not have an id field (or any other primary key), because it doesn''t make sense to have one.

Hi, Sorry to bother, but I checked around and did not succed creating a bundle from six existing packages (which are checkable, installable, etc. individually).

Dear Christian, Every single time check update package, ?cwhmisc? always requests updating. I?m aware that the package was latest updated in CRAN on 20Nov2008. Is there anything wrong with my R library or somethingelse? I use R 2.8.1 on Window XP service pack 2 Regards Nguyen Garvan Institute of Medical Research Sydney, Australia
