similar to: nls: Missing value or an Infinity produced when evaluating the model

Hi, I posted a question (bellow) a few weeks ago and had a reply (thanks Christian) that partly solves the problem, but I still would like to be able to restrict some of the independent variables in a nls model to be always >0, (is there a way to do it)?? Thanks, Angel >From: "Christian Ritz" <ritz at dina.kvl.dk> >To: "Angel -" <angel_lul at

Hi all I try to make a weibull survival analysis on R. I know make this on GLIM, and now I try to make the GLIM exercice GLEX8 on R to learning and compare the test. The variables are: time censor group bodymass In GLIM I make: $calc %s=1 $ to fit weibull rather than exponential $input %pcl weibull $ $macro model group*bodymass $endmac$ $use weibull t w %s $ Then, GLIM estimate an alpha for the

According to the AppDB, the Infinity Combat Prototype works perfectly. Unfortunately, when I try to run it, it freezes when it tries to load OpenAL. I've tried installing the OpenAL stuff linked to on the DB entry: no effect. Stderr shows nothing useful when running it and running it with WINEDEBUG=+openal32 shows nothing more.

I have to calculate some formula like: gamma(x)/(gamma(x+y) and I observed that for relatively big values of x, R returns infinity and so cannot compute the formula. Is it possible to force R to give the real value of gamma(x) instead of Inf ? thanks

Hi r-users, How do we evaluate the summation of (1/m!) from 0 to infinity (for example). Any help is very much appreciated. Thank you.

Hello everyone, I am looking into time series data compression at the moment. The idea is to fit a curve on a time series of n points so that the maximum deviation on any of the points is not greater than a given threshold. In other words, none of the values that the curve takes at the points where the time series is defined, should be "further away" than a certain threshold from the

Hi list. I''m writing a program that stores a lot of Floats into MySQL database. Simplified version of the program use the following form of class. class Val < ActiveRecord::BASE end And Vals table contains one column: num double One of my data contains -Infinity for num and when I try to Val.new Val.num = <- Here goes -Inifinity Val.save! Then the program crashes:

This doesn't seem to be happening on MacOS, neither in Terminal nor RStudio, (R 3.5.1, R-devel, R-patched).

sorry the integration was from -Inf to 1.96 The integrate function in R is not taking Inf (infinity). How do you use infinity in R. I was doing: integrate(dnorm,- Inf, 1.96) and I was getting Error: NA/NaN/Inf in foreign function call (arg 2). Obviously this should be equal to pnorm(1.96)= 0.9750021. How do you get around the infinity problem in R?

There seems to be something odd with "?" on Windows (and not only with read.table) In native encoding (cp-1252 in my case), "?" gets converted to "8" x <- "?" Encoding(x) #> [1] "unknown" print(x) #> [1] "8" charToRaw(x) #> [1] 38 "?" is indeed "8" identical(x, "8") #> [1] TRUE Everything

I'd like to be able to modify axlab in (C) below so that 'Inf' is replaced by the infinity symbol. y <- rnorm(40) breaks <- c(-Inf, -1, 1, Inf) x <- cut(y, breaks=breaks) plot(unclass(x), y, xaxt="n", xlab="") ## A: The following gives the axis labels "(-Inf, 1]", etc. axis(1, at=1:3, labels=expression("(-Inf,-1]", "(-1,1]",

Hi, I am a non-expert user of R. I am essaying the fit of two different functions to my data, but I receive two different error messages. I suppose I have two different problems here... But, of which nature? In the first instance I did try with some different starting values for the parameters, but without success. If anyone could suggest a sensible way to proceed to solve these I would be

This seems like such an obvious idea that I''m having trouble believing I''m the first to think of it. Why not take ranges containing Float::INFINITY and translate them to the appropriate greater than or less than comparisons? Example: class Person scope :voters, -> { where(born_on: (-Float::INFINITY..18.years.ago)) } end This would generate something along the lines of

Tomas, > In my scenario, the conversion is invoked by RGui before returning the input to the main R loop, even before the input gets to the parser. In principle, we could change this particular conversion in RGui to avoid the substitution. Not sure whether I am missing something here, but I used RStudio for my examples (I should have said) and David's mentioned RStudio as well, so it does

Bug Using read.table(file, encoding="UTF-8") to import a UTF-8 encoded file containing the infinity symbol (' ? ') results in the infinity symbol imported as the number 8. Other Unicode characters seem unaffected, example, Zhe: ? Expected Behavior: The imported data.frame should represent the infinity symbol as the expected 'Inf' so that normal mathematical operations

I can confirm that it doesn't happen on Ubuntu 18.04.1 so Peter is most likely correct; it looks like its Windows specific.

I can reproduce this behavior on my Windows 10 system in RGui (cp1252): when I paste the Unicode infinity symbol into the console, it is treated as number 8. This is caused by Windows "best fit" default behavior in conversion of unicode characters to characters in the current native encoding: at some point in the past, 8 has been chosen as a good fit for infinity in Windows. In my

Dear all, I am a relative novice with R, so please forgive any terrible errors... I am working with a GLM that describes a response variable as a function of a categorical variable with three levels and a continuous variable. These two predictor variables are believed to interact. An example of such a model follows at the bottom of this message, but here is a section of its summary table:

Hello! How can I test if floating-point value is NaN or positive/negative infinity?
