Dear list members, I frequently program small scripts and wrap them into functions to be able to check them with checkUsage. In case these functions (loaded via source or copy pasted to the R console) use functions from other packages, I get this error: no visible global function definition for ?xxxxxxx? For example: test = function() { require(plotrix) color.legend() }

Hi the list, Considere the following: f <- function(x){apply(x,2,mean)} findGlobals(f) findGlobals consideres mean as a global variable, which it is not. Is there a way to tell to findGlobals that mean is a function ? Thanks Christophe

Greetings I want to take a fitted regression and replace all uses of a variable in a formula. For example, I'd like to take m1 <- lm(y ~ x1, data=dat) and replace x1 with something else, say x1c, so the formula would become m1 <- lm(y ~ x1c, data=dat) I have working code to finish that part of the problem, but it fails when the formula is more complicated. If the formula has log(x1)

Last week one of our clients reported trouble with a csv file I generated with write.table. He said that columns with quotes for character variables were rejected by their data importer, which was revised to match the way Microsoft Excel uses quotation marks in character variables. I explained to them that quoted character variables are virtuous and wise, of course, but they say Microsoft Excel

According to http://www.redhat.com/magazine/006apr05/features/selinux/ there is a package named selinux-policy-strict, which contains a series of rules for correctly handling many situations (software) when using strict policy. Does CentOS have this package available ? If not, can someone make it available through Centosplus or Addon, for example ? This package is not part of the upstream main

I'm looking for an R mentor. I want to propose a change in management of plot options xlim and ylim. Did you ever want to change one coordinate in xlim or ylim? It happens to me all the time. x <- rnorm(100, m=5, s=1) y <- rnorm(100, m=6, s=1) plot(x,y) ## Oh, I want the "y axis" to show above x=0. plot(x,y, xlim=c(0, )) ##Output: Error in c(0, ) : argument 2 is empty

Is there a way to specify "strict modes = false" on the client side? I'm having trouble getting the client to accept the password file on Windows 2000, since rsync doesn't want the file to be other-readable, but this concept doesn't map too well to Windows. Alternatively, if I could simply set the proper permissions on the passfile, that would suit me fine, but it seems

Hi all, Is there any way to support calling external libraries from interpreted code (*not* JITted code) within lli? I am looking at the external functions implementation, and it seems just to wrap back onto its own library, looking up lli_X_... prefixed functions. It would (for obvious reasons) be incredibly useful not to be restricted to the (tiny) set of supplied functions. Thank you in

Hello, in addition to my last thread about a new config option to make strict-kex mandatory, I also wonder if a new mechanism for ciphers/macs can be introduced and is reliable by simple both sides using it. So there could be a Chacha20-Poly1305v2 at openssh.com which uses AD data to chain the messages together, so it will be resistant against terrapin even without the strict-kex. Consequently

I was wondering whether there might be anything in the JIT support that could be reused for

Dear all, while looking at some R-code submitted by students in a unit that I teach, I came across constructs that I thought would lead to an error. Much to my surprise, the code is actually executed. A boiled down version of the code is the following: > tt <- function(x, i){ + mean(x[i,2])/mean(x[i,1]) + } > dat <- matrix(rnorm(200), ncol=2) > mean(dat[,2])/mean(dat[,1]) [1]

I've been doing some consulting with students who seem to come to R from SAS. They are usually pre-occupied with do loops and it is tough to persuade them to trust R lists rather than keeping 100s of named matrices floating around. Often it happens that there is a list with lots of matrices or data frames in it and we need to "stack those together". I thought it would be a simple

Hi All, I hope someone can give me a hint. We try to reload the asterisk dialplan config using ansible command module. Using this we just trigger asterisk -rx "dialplan reload" Now we want ansibe to fail if there is something wrong in the dialplan. If we put a bad config in extensions.conf dialplan reload prints some warning in Asterisk console but the command "asterisk
