Hello, everybody. We are working on a tool for mutation testing. The work is still in progress and far away from being done. However, we have got some results already. And we would like to share them with you. But, let me give you a brief introduction first. ### Mutation Testing In a nutshell, Mutation Testing is a way to evaluate a quality of a test suite. The approach suggests introducing a

Good Afternoon, My name is Gabriel, I'm doing an analysis if there is increase or decrease in dependence on the mutated genes, using 3 or more genes using the fisher exact test.I performed with success an analysis for two genes using fisher.test( ). example of the 2x2 contigency table: Gene A mutated | Gene A normalGene B mutated| 26

Hello Everyone, I have what I think is a complex text parsing task. I've provided some sample data below. There's a relatively simple version of the coding that needs to be done and a more complex version. If someone could help me out with either version, I'd greatly appreciate it. Here are my sample data. haveData <- structure(list(profile_key = structure(c(1L, 1L, 2L, 2L, 2L,

Hello All, Started out awhile ago trying to select columns in a dataframe whose names contain some variation of the word "mutant" using code like: names(KRASyn)[grep("muta", names(KRASyn))] The idea then would be to add together the various columns using code like: KRASyn$Mutant_comb <- rowSums(KRASyn[grep("muta", names(KRASyn))]) What I discovered though, is

Hello All, Can anyone tell help me understand why the function below doesn't work and how I can fix it? Below are some sample data, some code that works on individual rows of the data, and my attempt to translate that code into a function. My hope is to get the function working and then to apply it to the larger data frame using ddply() from the plyr package or possibly some other approach.

Dear R-Users, Did anyone follow more closely the SARS Cov-2 lineages? I have done a quick check of Cov-2 mutations on the list downloaded from NCBI (see GitHub page below); but it seems that the list contains the cumulative mutations only for B.1 => B.1.1, but not after the B.1.1 branch: # B.1 => B.1.1 seems cumulative diff.lineage("B.1.1", "B.1", data=z) # but B.1.1

Hello I have a question. I made an r-script and did a few commands needed to make some new variables. They all work out well, and when I run the commands, the new variables appear in the dataset. I can also work with these new variables to make other new variables from them. Also, when I use summary(dataset), those new variables appear in the summary of the dataset. But, when I do summary(new

Hello - does anyone know whether there are any packages for Mann-Kendall mutation tests in R available? The only one I could find online is this MK_mut_test: Mann-Kendall mutation test in Sibada/sibadaR: Sibada's accumulated R scripts for next probably use to avoid reinventing the wheel. (rdrr.io) <https://rdrr.io/github/Sibada/sibadaR/man/MK_mut_test.html> but there doesn't seem to

Hello, Why are ValueSymbolTable's mutators all private? I can't seem to find a way to add a symbol to the table without using one of them. It looks like a bug to me since there is no way to use it otherwise. --Sam

Hi Chris, I was thinking that CreateValueName() was the way to add a symbol to a symbol table. Perhaps I'm thinking about this wrong. Here's what I've got: I've got a string generated by the parser which is constant. I need to add it to the symbol table so that, on starting the second pass of my compiler, I can dump all of the string constants to be generated as code. I

Hi, I have the following data: Path_Number <- 5 ID.Path <- c(1:Path_Number) # Make vector of ID's. No_of_X <- sample(50:550, length(ID.Path), replace=TRUE) # X <- split(sample(1:10000, sum(No_of_X), replace=TRUE), rep(ID.Path, No_of_X)) Y <- lapply(X,function(x) sample(x, round(runif(1, min=10, max=50)))) X and Y are both lists, and I've made the following function to

...s R scripts often populate the global environment with many variables, which may be mutated. Although this makes sense given R has historically been used interactively and this practice is common for scripting languages, this appears to disagree with the software-engineering principle of avoiding a mutating global state. Although this is just a rule of thumb, in R scripts, the frequent use of global variables is much more pronounced than in other languages. On the other hand, in Python, it is common to use a main function (through the `def main():` and? `if __name__ == "__main__":` idioms)....

Buenas, las imágenes no se ven por lo que no puedo reproducir tu ejemplo, pero tal vez lo siguiente te valga: > library('stringr') > d <- data.frame(respuestas = c('manzana, naranja', 'manzana, melocotón', 'naranja, melocotón')) > d respuestas 1 manzana, naranja 2 manzana, melocotón 3 naranja, melocotón > d$manzana <-

I ran into an interesting issue today with ActiveRecord''s becomes method and discovered that it is mutating the receiver without me knowing it. The API docs<http://api.rubyonrails.org/classes/ActiveRecord/Persistence.html#method-i-becomes>say "The new instance will share a link to the same attributes as the original > class. So any change to the attributes in either instance will affec...

I love the pointer analogy. Presumably the additional complication of scope breaks this however. * itself would have been a nice operator for this were it not prone to ambiguity (`a * *b` vs `a**b`, from which @ does not suffer). Would this extension require that function authors explicitly enable auto-quoting support? I somewhat envisioned functions seeing the resolved unquoted object (within

Function has its own FunctionType* member as well as a Type* member that it inherits from GlobalValue. The latter can be mutated but not the former, leading to potential strange inconsistencies. While I realize using mutateType is probably going to trigger a bunch of "you're doing it wrong" replies, it seems like mutateType, as a necessary evil, should be virtual and do the right

Hi, I am looking for genetic optimization package that allow to define my own chromosome solution and crossover/mutation opoerations. I checked genoud and genopt, not with much effort of 'cause, with no luck. Any one can shed some light on this? thanks.

Dear ladies and gentlemen, I have recently installed the latest version of R (4.3.3) for windows. Now I have the following problems with mutated vowels like ?, ?, etc. Here is an example: If I type the command: Dir <- "C/Users/macho/Documents/_LVn/Experimentelle ?bungen" in the R console there is no problem. However, if I put the same command into a source file (e.g. Test.r) and call

Dear mailing list, I'm stuck with a tricky problem here - at least it seems tricky to me, being not really talented in pattern matching and regex matters. I'm analysing amino acid mutations by position and type of mutation. E.g. (fictitious example) in position 92, I can find L92V, L92MV, L92I... L is in this example the wild-type amino-acid, and everything behind the position number is
