Hello, I am working on tests to compare figures. I have been using ImageMagick, which creates a figure signature, and I can compare a "test" figure signature against a saved "reference" figure signature. It seems to work pretty well. However, it is slow as it requires reading from the file system. Are there any options to compare figures on memory? For example, if I

I suggest perceptual diff. You could write a wrapper around it. http://pdiff.sourceforge.net On Mon, 7 May 2018 16:49 Ramiro Barrantes, <ramiro at precisionbioassay.com> wrote: > Hello, > > I am working on tests to compare figures.

Hello, I am working on a web system (php) that uses R in the backend, and we need some basic fast encryption/decryption for the underlying mysql database that can be used by both R AND php. It does not need to be top-of-the-line, but just provide some basic level of fast encryption/decryption. Any suggestions? Thank you, Ramiro [[alternative HTML version deleted]]

Hello, I have a program that consists of a loop fitting a function over many models. Sometimes the fitting on a particular model takes minutes to converge. Is there a way that I can limit the amount of time that R spends on a given model: say if my line is: fittingFunction( func, model.1) can I have some function: stopIfUnderTime( fittingFunction( func, model.1) , 5 ) where

Hello, I come from using different programming languages (C++, Mathematica, Perl) but have been using R extensively for several months. I see the data frame as a key piece of the language and wanted to inquire people's experience regarding its use. Say you have a data frame D D <- data.frame(some columns) and you define a function that needs the information from this data frame and is

Hello, I was relying on withTimeout (from R.utils) to help me stop nlme when it ?hangs?. However, recently this stopped working. I am pasting a reproducible example below: withTimeout should stop nlme after 10 seconds but the code will generate data for which nlme does not converge (or takes too long) and withTimeout does not stop it. I tried this both on a linux (64 bit, CentOS 7, R 3.4.1,

Hello, I tried looking for a Sweave-specific list but didn't find one, nor did I find an answer via google, so will send this question to the general R list. Please feel free to point me in the right direction. I am using Sweave and would like to have a single .Rnw document that generates 1) a summary report, 2) a full report, 3) slides for a talk. I think my material lends itself to have

Hello, I am using CentOS Linux 6.0, R 2.14.1 and nlme 3.1-103 I am trying to fit some models using nlme, and what was happening was that it would get to some datasets and just "stall", the memory usage would grow and grow and eventually crash. I looked carefully into one of the datasets and ran it separately. It worked. After narrowing down on all possibilities, I found that the main

Dear list, I am trying to reclaim what I think is lost memory in R, I have been using gc(), rm() and also using Rprof to figure out where all the memory is going but I might be missing something. I have the following situation basic loop which calls memoryHogFunction: for i in (1:N) { dataset <- generateDataset(i) fit <- try( memoryHogFunction(dataset, otherParameters)) } and

Hello, I am developing some packages. Package1 requires Package2, both of which I developed: Right now Package2 is installed properly here: /myHome/libraries/Package2 Package1 needs Package2. Package1 refers to Package2 both in the Roxygen @import field for one of the functions, and also in the Imports section in the DESCRIPTION However, when I do ?R CMD check Package1? I get: * checking

Hello, I am trying to convert BY to a data frame, consider the following example: exampleDF<-data.frame(a=c(1,2),b=c(10,20),name=c("first","second")) exampleBY<-by(exampleDF,with(exampleDF,paste(a,b,sep="_")),               function(x) {                 data.frame(                     name=as.character(x$name),                     a=x$a,                    

Hello, I have a general question on the possibility of how to "catch and stop" a function when it uses too much memory. The problem is that some datasets, when applied to nlme (a relatively older version), cause the nlme function to just hang forever and start taking over memory (this afternoon one of those calls was about 40GB!) and not returning an answer. Other datasets work fine.

Hello, I have again a "good practices"/programming theory question regarding data.frames. One of the fundamental objects that I use is the data frame with a particular set of columns that I would fill or get information from, and an entire system would revolve around getting information from or putting information to such data.frame. On a different OOP programming language I would be

Hello: We have a TDM2433E Digium Card (12 FXS, 12 FXO) and Asterisk 1.8.7.0 running. Everything seems to be ok but call transfers. This is the issue: *A, B, C and D are in FXS ports*. 1) A calls B. B anwers. 2) B tries to transfer the call to C dialing *2 (code for attended transfer). 3) A hears MOH. B dials number C. 4) Asterisk says the dialed number is incorrect or non existing. We tried

... are they possible?, or better yet: Are they enhacements at all? First, make it possible to use the vars defined in the params file usable in the policy and shorewall.conf also. Second, make it possible to specify a pseudo log level like NULL, SWNULL (SW by Shorewall) or an appropiate name that would have the same effect as not specifying a log level at all. These modifications together

I have data that looks like this: > df1 group id 1 red A 2 red B 3 red C 4 blue D 5 blue E 6 blue F I want a list of the groups containing vectors with the ids. I am avoiding subset(), as it is only recommended for interactive use. Here's what I have so far: df1 <- data.frame(group=c("red", "red", "red", "blue",

You can have multiple vethX interfaces on recent builds -- see netback/loopback.c. I think the current default is a rather miserly 1 (and should be increased), but can be set on the command line.
