There are a number of functions that are dispatched to from split(). > methods('split') [1] split.data.frame split.Date split.default split.POSIXct Is there a way to figure out which of these variants is actually dispatched to when I call split? I know that if the argument is of the type data.frame, split.data.frame will be called? Is it the case that if the argument is not

Here are my findings: -It seems that Alpha Vantage's OHLC data are unadjusted, and the adjusted close column provided is adjusted for splits, and split-adjusted dividends. -If I use AV's adjusted close column to adjust my OHCL data, my data will be adjusted for splits, and split-adjusted dividends. (So, I can use adjustOHLC(), with argument use.Adjusted = TRUE to adjust for splits, and split-adjusted dividends) Evidence: ### libra...

Hi all, In the help of strsplit one can read split character vector (or object which can be coerced to such) containing regular expression<http://127.0.0.1:39783/help/library/base/help/regular%20expression>(s) (unless fixed = TRUE) to use for splitting. If empty matches occur, in particular if split has length 0, x is split into single characters. Ifsplit has length greater than 1, it is

Hello, I’d like to give a status update to the community about the recently-added hot/cold splitting pass. I'll provide some motivation for the pass, describe its implementation, summarize recent/ongoing work, and share early results. # Motivation We (at Apple) have found that memory pressure from resident pages of code is significant on embedded devices. In particular, this pressure spikes

The splitting pass currently doesn’t move cold symbols into a separate section. Is that affecting your results? On Darwin, we plan on using a symbol attribute to provide an ordering hint to the linker (see r352227, N_COLD_FUNC). vedant > On Jan 28, 2019, at 10:51 AM, Aditya K via llvm-dev <llvm-dev at lists.llvm.org> wrote: > > Very happy to see good results.

Dear R-users, The following code splits a very simple dataframe into a list, each element of the list being one line of the dataframe. You will see that the split function names each element of the list by using uses the content of a and b and merging them with a "." character. Is there a way to customize this character? a<...

...= rep(c("A", "B"), 50)) I know I can split it by fac1, fac2 by: split(dat, list(dat$fac1, dat$fac2)) which gives a list of length 8 - as desired. My question is, given a vector of column name(s) to split by, how can I supply split with these? I was thinking something like: splits <- c("fac1", "fac2") split(dat, list(splits)) But that is clearly wrong....and I can't see the solution Many thanks David Carslaw Science Policy Group Environmental Research Group MRC-HPA Centre for Environment and Health King's College London Room 4.129 Frankli...

I am very sorry for such a simple question, but I am struggling with "split". I have the following data frame: x<-data.frame(A=c(NA,NA,NA,NA,"split",NA,NA,NA,NA,"split",NA,NA,NA,NA,"split",NA,NA,NA,NA),

I want to implement the following algorithm in R: I want to split my data, use a t test to compare both means of the groups to see if they significantly differ from each other. If this is a yes (p < alpha) I want to split again (into 4 groups) and do the same procedure twice, and stop otherwise (here the problem arises). As a final result I would have different groups of data. I made some

Hello, I very much enjoy "with" and "subset" semantics for data frames and was wondering if we could have something similar with split, basically by evaluating the second argument "with" the data frame : split.data.frame function(x, f, drop = FALSE, ...){ call <- match.call( ) fcall <- call( "with", data = call[["x"]],

I didn't see anything on this in the bug reports, and a search of the archives had lots of false positives when searching on "split" to be helpful. I don't view this as particularly interesting or useful, but wanted to report it because I stumbled on it (and don't remember ever seeing "invalid permissions" as part of a segfault).? Yes, I realize this is a silly

...ting allocation state to make those decisions we may have trouble: In RAGreedy some "current" colorings may be revisited, but during spilling in PBQP we're guaranteed that *all* colorings will be revisited in the next round, which may throw trySplit's heuristics out. trySplit splits either the given virtual register or some of its interference to make it colorable based indeed on the current state of allocation. That being said, I do not know if would really be a problem if you would revisited everything in the next round. I guess it would depend how you handle coalescing for...

Copies somewhat from the file plugin, with the difference that we always provide an .extents even if one or more of the split files does not support SEEK_HOLE. Testing is possible on a file system that supports sparse files when using nbdsh.

I'm having trouble using split on a very large data-set with ~1400 levels of the factor to be split. Unfortunately, I can't reproduce it with the simple self-contained example below. As you can see, splitting the artificial dataframe of size ~13MB results in a split dataframe of ~ 144MB, with an increase memory allocation of ~10 fold for the split object. If split scales linearly, then my
