Hi Evan, You may find some parts of what we are doing with genthat useful. Genthat is a tool for creating unit tests by recording argument and return values of calls. This is done by instrumentation of the source code. The git repo with the code is here https://github.com/PRL-PRG/genthat We don?t really deal with NSE though. It could be something worth thinking about for us. The contact for

I have tried to compile kde window decorator, but "configure" don't check my Qt installation and it don't have a option to specify the path. Thanks for your

Evan, The pryr package provides some utilities which may be handy here. In particular see the function: is_promise. Also, next time please post in plaintext. Regards Ben > 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

Hi all, I would like to install a trace function that gets executed whenever *any* R function is called. In Python, for example, this functionality is provided by the `sys.settrace` function. I am not aware of any public interface, at the R or C level, that can accomplish this. The `trace` function is inadequate because it does not support nested functions. The `Rprof` function provides only

The setup: I have a data frame where one column is in list mode, and each entry contains a vector of varying length. I want to expand this into a data frame with one row for each member of the list-mode column (the other values being replicated) For example, an example input and the desired output would be: input <- data.frame(site = 1:6, sector =

I'm trying to move from Matlab to R, and I'm stuck even getting started. This sounds to me like the dumbest question in the world but... how does one put R source code in files? Over the last three days I've gone front to back through the Introduction to R and the R Language Definition, and while I'm excited that the language is so Lispish, none of what I read described how to

When complex assignments are performed, the R interpreter creates, then removes a special variable *tmp*. However, when byte compiling is enabled, it seems that a different mechanism for making compound assignments is used. Would it be possible to eliminate *tmp* from interpreted R code as well? It might be useful for a function to lock its own environment, and the appearance and disappearance of

Everyone, I am building a gateway server with a new : CentOS Linux release 7.3.1611 (Core)??with 3.10.0-514.2.2.el7.x86_64 kernel. Everything was going find, but I was not able to get a particular cronjob to function properly that contained a perl script with Astro::Time as an include file. Astro::Time was installed with the use of the cpan module downloaded from the Centos repositories. The

Consider the data.frame: df <- data.frame(A = c(1,4,2,6,7,3,6), B= c(3,7,2,7,3,5,4), C = c(2,7,5,2,7,4,5), index = c("A","B","A","C","B","B","C")) I want to select the column specified in 'index' for every row of 'df', to get goal <- c(1, 7, 2, 2, 3, 5, 5) This sounds a lot like the indexing-by-a-matrix

Hi, Short version of my question: Rf_applyClosure was marked attribute_hidden in Oct 2023, and I am curious why and if there is an alternative interface to it planned. Long version: I have been toying with building a package that makes it easier to do non-standard evaluation directly using promises, rather than wrapping these in a custom type (like e.g. rlang does). The advantage of this

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'm trying to massage some data from Matlab into R. The matlab file has a "struct array" which when imported into R using the R.matlab package, becomes an R list with 3+ dimensions, the first of which corresponds to the structure fields, with corresponding row names, and the second and third+ dimensions correspond to the dimensions of the original struct array (as matlab

This is tangentially related to Hadley's question. Suppose I'm building a function programmatically; I have assembled an expression for the body and I know the names of the arguments it wants to take. Suppose I have some convenience function such that writing make_function(alist(a=, b=), quote(a+b), environment()) is equivalent to writing function(a,b) a+b So how do I make the

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.

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
