I have a dataframe of animal locations that I need to have in incremental order so that I can calculate the distance traveled between each time step. However, I have identified a few values that don't seem to sort properly. For instance, the last value in the table below should be the first value after sorting, since its time value is '00:01:35'. But, for some reason, it seems to be

I have a series of animals that are being radio-tracked. I have written some code that goes through each animal and calculates the total distance that each animal is traveling. I will need to run these data on a regular basis and want to write the result to a .php webpage file so that the page updates automatically when I re-run the code. I thought I'd be able to use the

Hello All I, for the life of me, can't figure out to subset my dataframe by my Date field. The field has been formatted as POSIXlt. str(wild) ...... $ Date : POSIXlt, format: "2010-05-28" "2010-05-28" "2010-05-28" ... This doesn't work: test <-subset(wild,ID=="2830" & Date=="2010-08-17") which returns: <0 rows> (or

Dear All! It's now weeks that I'm going crazy with R, and as I'm a new user I now ask for help (also because I still have only a few days to finish..)... So shortly I describe you my Experiment in which I was looking for the decomposition of herbivore dung under different treatments: I made a box design experiment which is structured in the following way: I collected dung from 2

Hi All, I'm happy to announce that Apple has agreed to let llvm.org (and anyone else) use the great LLVM logo they designed for WWDC. If you're interested, you can see the full version of the logo on this page: http://llvm.org/Logo.html I personally think that this is a pretty great logo/mascot for LLVM, because it is very abstract, can be adapted in a variety of ways, is

I have read just the comment from Mark Wielaard, the leader of GNU Classpath: http://gnu.wildebeest.org/diary/index.php?p=129 And after that I have a question, if somethinl like Mauve exists also for WINE/ReactOS? GNU Classpath is a OpenSource-Version of the Java Standard Edition Classes. And Mauve are testclasses, which test, that the OpenSource JVMs with GNU Classpath are still working

Hello, I am working on a paper of ecological modelling in R. I have made a Lotka Volterra model for tree animal species. I was trying to get the model in R but there are some errors. Since i am not so experienced with R i can't find the bugs in my script. I hope if there is someone who can help me handle this problem. Greetz Roel This is the script i wrote: library(odesolve) LotVmod

Hello, Is there a faster way to do this? Basically, I'd like to NA all values in all_data if there are no 1's in the same column of the other matrix, iu. Put another way, I want to replace values in the all_data columns if values in the same column in iu are all 0. This is pretty slow for me, but works: all_data = matrix(c(1:9),3,3) colnames(all_data) =

Dear R-developers, I came to a somewhat unexpected behaviour of read.csv() which is trivial but worthwhile to note -- my data involves a protein named "1433E" but to save space I drop the quote so it becomes, Gene,SNP,prot,log10p YWHAE,13:62129097_C_T,1433E,7.35 YWHAE,4:72617557_T_TA,1433E,7.73 Both read.cv() and readr::read_csv() consider prot(ein) name as (possibly confused by

I have been trying to use R to gather some information from parsed log files (as part of examining some performance issues). I parsed the log files and put the data into an SQLite database, and then used RSQLite to load the data into R. The fields of interest are controller, action and total_time: controller and action have string values; total_time has a decimal value. I first did the

I all, is there a way with R to perform an exact permutation test to replace the wilcoxon test to compare paired series and/or to perform pairwise multiple comparisons for related series after a Friedman test ? Thanks Gilles

Gene names being misinterpreted by spreadsheet software (read.csv is no different) is a classic issue in bioinformatics. It seems like every practitioner ends up encountering this issue in due time. E.g. https://pubmed.ncbi.nlm.nih.gov/15214961/ https://genomebiology.biomedcentral.com/articles/10.1186/s13059-016-1044-7 https://www.nature.com/articles/d41586-021-02211-4

Hello the code : set.seed(10) y<-c(1:1000) x1<-c(1:1000)*runif(1000,min=0,max=2) x2<-c(1:1000)*runif(1000,min=0,max=2) x3<-c(1:1000)*runif(1000,min=0,max=2) lm_fit<-lm(y~x1+x2+x3) summary(lm_fit) set.seed(10) all_data<-data.frame(y,x1,x2,x3) positions <- sample(nrow(all_data),size=floor((nrow(all_data)/4)*3)) training<- all_data[positions,] testing<-

Your message seems unclear, and as evidence the respondents are giving various answers. You should provide a small sample of input and output data as it would look in R to avoid this kind of thrashing about. See [1][2][3] for guidance. Note that you also really need to figure out how to make sure your email program sends plain text, because HTML formatting WILL be stripped by the mailing list

Hello All, I have a data frame consisting of 4 columns (id1, id2, y, pred) where pred is the predicted value based on the glm function and my data frame is called "all". "data" is another data frame that has all data but I want to put together some important columns from my original data frame (data) into another data frame (all) as follows and I would like them to be sorted

Hi, I am pretty new to R and I would apreciatte very much your help to solve my problem. I have 40 csv files that have the same structure, and I want to merge them into a single data frame. I already have load and combined all the cvs files into a large list, and I created two filenames <- list.files('data',full.names=TRUE) All_data <- lapply(filenames,function(i){ ###read cvs

Don't know if anyone's got experiences on this they'd be able to share... I'm trying to obtain numbers for Kenya/Nigeria, but I'm struggling to find a company selling them. There's one for Nigeria listed on didx.com, but $22/month seems a little steep. Has anyone had any luck getting DIDs for countries in Africa, and are there any companies out there selling them? Thanks
