best method to format output of frequency table
I have some security alert log data that I'm parsing and doing some stats on.
One of the fields is the "Classtype" which is the enumerated value of the
type of alert found.
classtypes = factor( alerts$Classtype )
fclass_types = table( classtypes )
fclass_types gives me a frequency table of the intrusion types:

[LLVMdev] Offset to C++ structure members
...uld be easy to write a "thunk" wrapper to call it. However, assume that there is no such S member function. I therefore need a way to get the offset of 'b' and add it to 's' so that I can call T_string_M_assign_Pv() on it.
Given this helper function:
template<class ClassType,class MbrType> inline
ptrdiff_t mbr_offset_of( MbrType ClassType::*p ) {
ClassType const *const c = static_cast<ClassType*>( nullptr );
return reinterpret_cast<ptrdiff_t>( &(c->*p) );
}
I could take a Pointer to an S, use ptrtoint, add the offset, use inttoptr, and u...

ALTREP package interaction with testthat
...LTREP package.
The package name is AltWrapper. My ALTREP serialize function is called even
when I'm trying to serialize a non-ALTREP object. Here is an example
```
context("altrep")
length_func<-function(x){
return(length(x))
}
setAltClass(className = "test", classType = "real")
setAltMethod(className = "test", getLength = length_func)
testData = runif(10)
myAltrep = makeAltrep("test", testData)
test_that("Auto serialize", {

[LLVMdev] Named metadata to represent language specific logic
Hi all,
I was wondering if we could use named metadata to store some of C++
logic without changing the IR. This is primarily only for front-end
buiding and the resulting IR (with or without metadata) should be the
same as it is today (or better).
I say this because of the number of global variables front-ends need
to keep because LLVM IR cannot represent all the information of types,
vatriables,

ALTREP wrappers and factors
Hello,
I?m experimenting with ALTREP and was wondering if there is a preferred way to create an ALTREP wrapper vector without using .Internal(wrap_meta(?)), which R CMD check doesn?t like since it uses an .Internal() function.
I was trying to create a factor that used an ALTREP integer, but attempting to set the class and levels attributes always ended up duplicating and materializing the
