similar to: Bug Report: read.table with UTF-8 encoded file imports infinity symbol as Integer 8

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

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

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

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

I'm trying to follow docs/Projects.html to use llvm in a project of my own. If I just copy the sample directory, running configure in the new one works fine: ~/programming/llvm-1.9/projects $ cp -a sample/ zhe ~/programming/llvm-1.9/projects $ cd zhe/ ~/programming/llvm-1.9/projects/zhe $ ./configure configure: creating ./config.status config.status: creating Makefile.common config.status:

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:

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]",

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?

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

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.

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

Hi, I am trying to fit a sigmoid curve to some data with nls but I am getting into some trouble. Seems that the optimization method is getting down to some parameter estimates that make the equation unsolvable. This is an example: >growth<-data.frame(Time=c(5,7,9,11,13,15,17,19,21,23,25,27),BodyMass=c(45,85,125,210,300,485,570,700,830,940,1030,1120))

Hi, I am a beginner for R. I had use gplots to generate a heatmap as following: >heatmap.2(matrix, col=topo.colors(75), dendrogram="column", Rowv=FALSE, trace="none", key=TRUE, keysize=0.8, density.info="none", cexRow=0.2, cexCol=0.6) It work well. It generate heatmap whith rcolumn clustering dendrogram and I can export a very nice graph. But I don not know how

Hi I want to do a series of linear models, and would like to define the input arguments for lm() as variables. I managed easily to define the formula arguments in a variable, but I also would like to have the "subset" in a variable. My reasoning is, that I have the subset in the results object. So I wiould like to add a line like: subs <- dead==FALSE & recTreat==FALSE which
