similar to: Calling applyClosure from a package?

Hello R experts, I plan to develop a tool for dynamic analysis of R programs. I would like to trace function calls at runtime, capturing argument and return values. Following a suggestion made some time ago on this list, my high-level implementation strategy is to rewrite the AST, augmenting call expressions with pre-call and post-call shims to capture the arguments and return value,

Sir, How to get the closing price from this link http://www.google.com/finance/historical?q=NSE:RCOM I installed quantmod getSymbols('NSE:RCOM',src='google') gives me this error********************** Error in download.file(paste(google.URL, "q=", Symbols.name, "&startdate=", : cannot open URL

This is hard if not impossible to implement for the general case because the default arguments are evaluated in the environment of the function as it

i am using quantmod package.it get stock quotes from google finanace. but unfortunately i am not able to get the quotations of some stocks(e.g. NSE:TCS,NSE:SAIL ) through the "getSymbol" command of this package although they are available in the google finance website. anyone please help me. thanks in advance..... -- View this message in context:

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

I have a Linksys PAP2. Identical setups for the two channels in both the unit and in Asterisk. In particular, both channels enable g729 and set it as the preferred codec, and have disallow=all and allow=g729 in sip.conf. If we make a call on one channel, it works (and uses g729), but if we make a call on the other channel when the first one is still connected, it fails. We have three g729

Hi everyone, I'm trying to send a FAX with the following configuration: Analog FAX machine (OKI) <----->SPA21000<----->LAN<----->Asterisk<--------> PSTN I'm restricted to use passthru mode for faxing, instead of T.38 protocol, because the Asterisk box is running v1.2 and cannot be changed as it is in a heavy production environment. Anyway, it "should"

This morning I discovered this in my clamav report from one of our imap servers: /usr/share/nmap/scripts/irc-unrealircd-backdoor.nse: Unix.Trojan.MSShellcode-21 FOUND I have looked at this script and it appears to be part of the nmap distribution. It actually tests for irc backdoors. IRC is not used here and its ports are blocked by default both at the gateway and on all internal hosts.

Hi, We found a (to our eyes) strange behaviour that might be a bug. First a little bit of context. The 'units' package allows us to set the unit using both SE or NSE. E.g., these both work in the same way: units::set_units(1:10, "?m") #> Units: [?m] #> [1] 1 2 3 4 5 6 7 8 9 10 units::set_units(1:10, ?m) #> Units: [?m] #> [1] 1 2 3 4 5 6 7 8 9 10

Greetings, I am porting the openssh-portable 6.8 release to the HP NonStop (NSE) platform. Prior versions were no real problem, with minor tweeks. However, with the inclusion of regress/netcat.c, which depends on arpa/telnet.h, we have an issue. Unfortunately, the platform does not have this file, nor anything like it - telnet is done rather differently. We do have a version of netcat (0.7.1

(please be gentle, it's my first time) I am interested in discussions (possibly reiterating past threads -- searching didn't turn up much) on the possibility of supporting standard evaluation unquoting at the language level. This has been brought up in a recent similar thread here [1] and on Twitter [2] where I proposed the following desired (in-principle) syntax f <-

Would this return a quosure? (i.e. a single sided formula that captures both expression and environment). That's the data structure we've adopted in tidyeval as it already has some built in support.

I'm trying to use the IAPWS95 package with the tidyverse packages. For some reason, the function is not outputting the correct rho. A minimal example with results is below. I've also included the definition of the DTp function from the IAPWS95 library. ==================================== library(IAPWS95) library(tidyverse) initial <- data.frame(T=c(279,294),p=c(0.46,0.46))

Non-standard evaluation, used widely in formula-interface functions as well as the tidyverse. with() in my example is a less nuanced version of this. See

Handling NSE in these kinds of examples is a pain in lattice. I would suggest using with() and dropping the data argument for simple examples, e.g., dd |> mutate(new.proportion = las/total, new.bubble = total/100) |> with(dotplot(agency ~ new.proportion, pch = 16, cex = new.bubble)) But if you care about multi-panel plots, you also need to be careful about making sure that the
