LLVM-based Mutation Testing, first results.
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...

Welcome to the "R-help" mailing list
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

Selecting columns whose names contain "mutated" except when they also contain "non" or "un"
...d be to add together the various columns using code like:
KRASyn$Mutant_comb <- rowSums(KRASyn[grep("muta", names(KRASyn))])
What I discovered though, is that this selects columns like "nonmutated" and "unmutated" as well as columns like "mutated", "mutation", and "mutational".
So I'd like to know how to select columns that have some variation of the word "mutant" without the "non" or the "un". I've been looking around for an example of how to do that but haven't found anything yet.
Can anyone...

DPLYR Multiple Mutate Statements On Same DataFrame
Hi R Helpers,
I have been looking for an example of how to execute different dplyr mutate statements on the same dataframe in a single step. I show how to do what I want to do by going from df0 to df1 to df2 to df3 by applying a mutate statement to each dataframe in sequence, but I would like to know if there is a way to execute this in a single step; so simply go from df0 to df1 while executing

Covid Mutations: Cumulative?
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 => B.1.1.529...

Error: variable not found
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

Mann Kendall mutation package?
Hello - does anyone know whether there are any packages for Mann-Kendall

[LLVMdev] ValueSymbolTable's mutators are private?
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.

[LLVMdev] ValueSymbolTable's mutators are private?
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

The mutators are things like Value::setName()

Stuck trying to modify a function
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

Conventions: Use of globals and main functions
...gramming, etc.) caution against assignment in a parent enclosure (e.g., using `<<-`, or `assign`), I have not seen many promote the use of a main function and avoiding mutating global variables from top level.
Would it be a good idea to promote use of main functions and limiting global-state mutation for longer scripts and dedicated applications (not one-off scripts)? Should these practices be mentioned in the standard documentation?
This question was motivated largely by this discussion on Reddit:?https://www.reddit.com/r/rstats/comments/cp3kva/is_mutating_global_state_acceptable_in_r/?. Apol...

RFC: (in-principle) native unquoting for standard evaluation
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

Functions have two types, one can be mutated but not the other
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

Which genetic optimization package allows customized crossover and mutation operation
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.
