Re: [R] Non linear regression - Von Bertalanffy Growth Function - singular gradient matrix at initial parameter estimates
Packages nlmrt or minpack.lm use a Marquardt method. minpack.lm won't proceed if the Jacobian singularity is at the starting point as far as I'm aware, but nlxb in nlmrt can sometimes get going. It has a policy that is aggressive in trying to improve the sum of squares, so will use more effort than nls when both work. JN On 15-08-18 12:08 PM, Xochitl CORMON wrote: Dear all, I am trying to estimate VBGF parameters K and Linf using non linear regression and nls(). First I used a classic approach where I estimate both parameters together as below with alkdyr being a subset per year of my age-length-key database and running in a loop. vbgf.par - nls(Lgtcm ~ Linf *(1 - exp(-K * (Age - tzero))), start = c(K= 0.07, Linf = 177.1), data=alkdyr) I obtain an estimation of both parameters that are strongly correlated. Indeed after plotting Linf ~ K and fitting a linear regression I obtain a function (Linf = a + b*K) with R2= 0.8 and a = 215, b = -763. In this context, to take into account explicitly correlation between parameters, I decided to fit a new non linear regression derivate from VBGF but where Linf is expressed depending on K (I am most interested in K). To do so, I tried this model: vbgf.par - nls(Lgtcm ~ (a + (b*k)) *(1 - exp(-k * (Age - tzero))), start = c(k= 0.07, a= 215, b=-763), data=alkdyr) Unfortunately at this point I cannot go further as I get the error message singular gradient matrix at initial parameter estimates. I tried to use alg= plinear (which I am not sure I understand properly yet). If I give a starting value for a and b only, I have an error message stating step factor below minFactor (even when minFactor is set to 1000).

Re: [R] Running R in Server
Dear all, Thenks for replying to my query. *@Amaud: If I understand correctly what you want to do, you might be able to create a HTML report using RMarkdown and host that on the website.

There is a free open-source solution for windows.* I'll check this. *@John: Statement: You have a Windows desktop and have used R on it, so you are familiar with R in a Windows environment.* *Statement: You are not Linux (Ubuntu) trained.* *Statement: You wrote an R script on Windows, which works, but you need to run it on Ubuntu.* *The above is my starting point. Now I have some questions.* *Can you connect to the Ubuntu server from your Windows desktop? If so, how? If not, I'm confused about how you could get anything to run on the Ubuntu server.* My developer has given me an username and password which I can use to connect the server using Putty. The GUI is being developed in Ubuntu server only using PHP and my the results of my RScript (figures and tables) will be the input of the GUI. Having said that, I have limited knowledge how to implement the R and run the script in server after loggin in to the server. *Where does this dataset reside? On you desktop? On a Windows shared folder? On the Ubuntu server? Other?* Right now, on my desktop. But soon the dataset will be residing on a server. *Who or what edits the dataset? That is, is it always yourself? Some one in your group? Some other human? Some automated process?* The input data of my Rscript again comes from another app and the database is also residing on the same server. The update of the dataset is being done by the app automatically. *Why can't you run the R script as you do now, then deploy the results to the Ubuntu server? Since I don't know the environment that the Ubuntu server runs in, I can't address how to deploy an updated file into it. I assume you have some sort of deployment software. It could be as easy as being able to ftp the results from your desktop to the proper places on the Ubuntu server.* I cannot run the R script as I do now because the Rscript will also be called for automatically so that the results of the Rscript go as an input to the end app. PFA the architecture picture. *@Loris: However, you'll probably have to make sure that all the packages you* *need are installed on the server.* This is where I need a help.

Hi, I've been led to believe that in R it is possible to produce a 3d analytical plot of a function.

And a smart person out there is going to tell me where this syntax comes from (or belongs to), there is also a R package called MapleSoft ( I believe) which is commercial, and there is always Mathematica. So is there a R function to plot z=f(x,y) without obtain or generating data.

[R] glm help
Dear All, I´m running a glm with poisson errors and have a doubt when ploting the predicted values. One of my variables has a positive slope in the summary output, but when I plot the predicted values on the original plot it draws a line with negative slope. I appreciate your comments on this and any other aspect of the analysis. Attached is the script and data in different formats just in case.

Re: [R] data format
This looks like data for a morphometrics analysis so you should know about package geomorph. Data like yours is often stored as a three dimensional array so we switch to that format and then use the two.d.array() function in package geomorph: Assuming your dataset is called dat: arr - array(as.matrix(dat[, -1]), dim=c(4, 2, 3)) library(geomorph) mat - two.d.array(arr) colnames(mat) - paste0(p, rep(1:4, each=2), + rep(c(x, y), 4), rep(1:4, each=2)) mat p1x1 p1y1 p2x2 p2y2 p3x3 p3y3 p4x4 p4y4 [1,]5 34 46 45 73 45 92 43 [2,]7 26 48 42 72 44 90 43 [3,]7 32 44 48 71 46 89 42 dat2 - data.frame(sample=1:3, mat) dat2 sample p1x1 p1y1 p2x2 p2y2 p3x3 p3y3 p4x4 p4y4 1 15 34 46 45 73 45 92 43 2 27 26 48 42 72 44 90 43 3 37 32 44 48 71 46 89 42 - David L Carlson Department of Anthropology Texas AM University College Station, TX 77840-4352 -Original Message- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of minikg Sent: Wednesday, August 19, 2015 9:29 AM To: r-help@r-project.org Subject: [R] data format Hi, I have a dataset consisting of landmarks of each sample's coordinates as given below. landmarkX Y X Y X Y P1 534 7 26 7 32 P2 46 45 48 42 44 48 P3 73 45 72 44 71 46 P4 92 43 90 43 89 42 please help me to change my data format to sample p1x1p1y1p2x2p2y2p3x3p3y3p4x4p4y4 1 534 46 45 73 45 92 43 2 726 48 42 72 44 90 43 3 732 44 48 71 46 89 42 Thanks -- View this message in context: http://r.789695.n4.nabble.com/data-format-tp4711278.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Plot z=f(x,y) analytically
You probably want function persp3d() in package rgl. You have to define the formula as a function and specify the limits correctly, but you were close: library(rgl) persp3d(function(x, y) x^2+y^2, xlim=c(-3, 3), ylim=c(-3, 3)) - David L Carlson Department of Anthropology Texas AM University College Station, TX 77840-4352 -Original Message- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of chappo007 Sent: Wednesday, August 19, 2015 6:48 AM To: r-help@r-project.org Subject: [R] Plot z=f(x,y) analytically Hi, I've been led to believe that in R it is possible to produce a 3d analytical plot of a function.

Re: [R] Plot z=f(x,y) analytically
R has several options for projecting a 3 dimensional plot onto a 2 dimensional plane and plotting the result. Which is best depends on what you want. You mention a function plot3d but not which package it comes from. You are more likely to receive prompt and useful help when you do your part of the homework and tell us which package it is from (it is not in the default packages). In fact, with a name like that, there could easily be more than one package with a function of that name and if we tell you how to use the function from a different package than you are using then the help will probably be more confusing than helpful. In base R you can use functions like persp, image, and contour (after using a function like outer), the help pages have examples. If you load the lattice package then you can use wireframe, levelplot, or contourplot, again the help pages have examples. The TeachingDemos package has functions rotate.persp and rotate.wireframe that create an interactive interface to the corresponding plots. The help page for the plot3d function in the RGL package (one likely candidate for the function you mentioned) points to the plot3d.function function in the See Also section which has examples that you could plug your function into.

My question isare 1, 2, and 3 all correct, and are there other coding schemes that glm can take. When in doubt, RTFM! :-) From ?binomial: For the binomial and quasibinomial families the response can be specified in one of three ways: As a factor: ‘success’ is interpreted as the factor not having the first level (and hence usually of having the second level). As a numerical vector with values between 0 and 1, interpreted as the proportion of successful cases (with the total number of cases given by the weights). As a two-column integer matrix: the first column gives the number of successes and the second the number of failures. That pretty well says it all. One thing to note: If the response is a *numeric* vector of 0's and 1's it will produce the same result as it would if it were converted to a factor. (This is because the default weights are all 1.)
