Thanks for the answers, I?m aware of the ?.? option, just wanted to give a very simple example. But the lapply ??' parameter use has eluded me and thanks for enlightening me. What do you mean by messing up the call stack. As far as I understand it, piping should translate into same code as deep nesting. So then I only see a tiny downside for debugging here. No loss of time/space efficiency

Regarding the anonymous-function-in-a-pipeline point one can already do this which does use brackets but even so it involves fewer characters than the example shown. Here { . * 2 } is basically a lambda whose argument is dot. Would this be sufficient? library(magrittr) 1.5 %>% { . * 2 } ## [1] 3 Regarding currying note that with magrittr Ista's code could be written as: 1:5

Dear R-devel, The most popular piping operator sits in the package `magrittr` and is used by a huge amount of users, and imported /reexported by more and more packages too. Many workflows don't even make much sense without pipes nowadays, so the examples in the doc will use pipes, as do the README, vignettes etc. I believe base R could have a piping operator so packages can use a pipe in

Hi John, Thanks, but the Bizzaro pipe comes with many flaws though : * It's not a single operator * It has a different precedence * It cannot be used in a subcall * The variable assigned to must be on the right * It doesn't trigger indentation when going to the line * It creates/overwrite a `.` variable in the worksace. And it doesn't deal gracefully with some lazy evaluation edge

The double quotes are required by SQL if a name is not of the form letter-followed-by-any-number-of-letters-or-numbers or if the name is a SQL keyword like 'where' or 'select'. If you are doing this from a function, you may as well quote all the names. -Bill On Fri, Oct 2, 2020 at 6:18 PM Philip <herd_dog at cox.net> wrote: > The \?2B\? worked. Have no idea why. Can

Hello everybody, sorry for stupid qustion, but I have following problem: I succesfully installed Dovecot on Debian (from source). Now I want to run it. I tryed: # /usr/local/dovecot/sbin/dovecot # but nothing happened: # ps -Af | grep dove ....... ps -Af | grep dove # What is wrong? I want Dovecot to serve POP3 over SSL. Many thanks and sorry again :o)

Hi Gabe, > There is another way the pipe could go into base R that could not be > done in package space and has the potential to mitigate some pretty > serious downsides to the pipes relating to debugging I assume you're thinking about the large stack trace of the magrittr pipe? You don't need a parser transformation to solve this problem though, the pipe could be implemented as

Yes but this exageration precisely misses the point. Concerning your examples: * I love fread but I think it makes a lot of subjective choices that are best associated with a package. I think it changed a lot with time and can still change, and we have great developers willing to maintain it and be reactive regarding feature requests or bug reports *.group_by() adds a class that works only (or

IMHO, if base R were to include a pipe operator, I think it should be much simpler than the magrittr pipe. It should satisfy the property that: x |> f(...) is equivalent to f(x, ...) Except, perhaps, in terms of when the promise for 'x' gets forced. We shouldn't need to mess with bindings in environments to make that work. My understanding is that the '.'

Hello, Here is one question regarding the LLVM TableGen: Which file in the llvm/lib/Target/X86 folder describes how the bits in the EFLAGS register are modified by the x86 instructions? For example, in the "X86InstrInfo.td" file, lines 2134-2135, it says: let SchedRW = [WriteALU], Defs = [EFLAGS], Uses = [EFLAGS] in { def CLC : I<0xF8, RawFrm, (outs), (ins), "clc",

Hi Philip, You've probably realized by now that R doesn't like column names that start with a number. If you try to access an R-dataframe column named 2B or 3B with the familiar "$" notation, you'll get an error: > library(DBI) > library(RSQLite) > con2 <- dbConnect(SQLite(), "~/R_Dir/lahmansbaseballdb.sqlite") > Hack12Batting <-

This is really a feature of SQL, not R. SQL requires that you double quote column names that start with numbers, include spaces, etc., or that are SQL key words. E.g., > d <- data.frame(Order=c("sit","stay","heel"), Where=c("here","there","there"), From=c("me","me","you")) >

Dear members, here is my trouble: My data consists of counts of trapped insects in different attractive traps. I usually use GLMs with a poisson error distribution to find out the differences between my traitments (and to look at other factor effects). But for some dataset where one traitment contains only zeros, GLM with poisson family fail to find any difference between this particular traitment
