similar to: Making parent.env<- an error for package namespaces and package imports

Dear r-devel, I was surprised to see that saveRDS() and readRDS() work quite well with environments, see below: ``` z <- 3 # in global env y <- new.env() y$a <- 1 x <- new.env(parent = y) x$b <- 2 saveRDS(x, "x.RDS") # in a new session x <- readRDS("x.RDS") y <- parent.env(x) x$b #> [1] 2 y$a #> [1] 1 parent.env(y) #> <environment:

Hi all, I have some code where I''d like to set up an instance of a non-database model from another, ActiveRecord, model in order to use some custom methods on a string, without mixing extra methods into the String class. I understand this might be less-than-sensible as models should normally stand on their own..? My two models: ####################### # models/qualified_name.rb #

Hi! Here is some output from an str command: > str(CO2) Classes ‘nfnGroupedData’, ‘nfGroupedData’, ‘groupedData’ and 'data.frame': 84 obs. of 5 variables: $ Plant : Ord.factor w/ 12 levels "Qn1"<"Qn2"<"Qn3"<..: 1 1 1 1 1 1 1 2 2 2 ... $ Type : Factor w/ 2 levels "Quebec","Mississippi": 1 1 1 1 1 1 1 1 1 1 ... $

In my database the id for a field is 810. RoR thinks that it is 809. My log file (below) shows that just before the insert it grabs the next sequence value. I dont think it should do that. This causes problems further down the line when trying to access the Person object. Development Log file : "SQL (0.016000) select people_seq.nextval id from dual Person Create (0.015000) INSERT

Dear all, When using gdb to debug my C code, I use R_PV to show the content of SEXP variables: SEXP sexp; // it is a data.frame SEXP colNames = getAttrib(sexp, R_NameSymbol); A strange thing is that after halting the program: (gdb) p R_PV(colNames) does not show the content of colNames. I am positive my code is right because if I insert "PrintValue(colNames);" in the c code,

My understanding is that R will not make copies of lists if there is only one reference to the object. However, I've encountered a case where R does make copies, even though (I think) there should be only one reference to the object. I hope that someone could shed some light on why this is happening. I'll start with a simple example. Below, x is a list with one element, and changing that

Hi, I would be nice if names() returned the equivalent of ls() for environments. --- a/src/main/attrib.c +++ b/src/main/attrib.c @@ -687,6 +687,8 @@ SEXP attribute_hidden do_names(SEXP call s = CAR(args); if (isVector(s) || isList(s) || isLanguage(s)) return getAttrib(s, R_NamesSymbol); + if (isEnvironment(s)) + return R_lsInternal(s, 0); return R_NilValue; }

1. Is there some way to copy a promise so that the copy has the same expression in its promise as the original. In the following we y is a promise that we want to copy to z. We want z to be a promise based on the expression x since y is a promise based on the expression x. Thus the answer to the code below is desired to be z=2 but its 1, 1 and y in the next three examples so they are not the

I am currently puzzled by a passage in the R Extensions manual, section 5.10: SEXP lapply(SEXP list, SEXP expr, SEXP rho) { R_len_t i, n = length(list); SEXP ans; if(!isNewList(list)) error("`list' must be a list"); if(!isEnvironment(rho)) error("`rho' should be an environment"); PROTECT(ans = allocVector(VECSXP, n));

Hello, Using R-devel (rev 53950), I get inconsistent results with as.environment( VECSXP ) when gctorture is on. Consider: a <- list( aa = rnorm, bb = runif ) gctorture(TRUE) as.environment( a ) The last line sometimes produces the correct environment, but sometimes I get errors. Here are the three situations: # good > as.environment( a ) <environment: 0x100b1c978> # not good

I just got a new PC at work. My project files were copied from my old drive. Just to be sure, though, I have erased them and pulled them back down from source control. My development database server is MySQL My test database server is sqlite3 I am having a confusing issue: tests are failing and errors are happening that weren''t happening before. Furthermore, they aren''t

I maintain the package affylmGUI. It works when installed on many previous versions of R. I have today tested exactly the same code under R-2.15.3, R-3.0.2, R-3.1.0, R-3.1.1, R-3.1.2 and R-devel. I have also tested the versions of affylmGUI downloaded by biocLite for each version of R and the same result applies. I have no errors under 2.15.3, 3.0.2, 3.1.0 and 3.1.1. The following error

I use Apache to serve the static pages and let Mongrel handle Rails requests via mod_rewrite/proxy. Apache RewriteRule can set environment variable on the fly, and this is one of the features I used, set an env var based on domain name. I used to use SCGI Runner which was fine as the env var was passed to Rails via scgi protocol. I seems can''t find a way to set env var in Mongrel on

Hi, today I''ve configured an XUbuntu as workstation (ok I know...). Using the following packages to make Rails interact with Postgres: ii libpgsql-ruby1.8 0.7.1-7 ii postgresql-8.1 8.1.4-0ubuntu1 using rails 1.1.6 from gems. The problem came up just on the testing environment, when I save a model I get a: ActiveRecord::StatementInvalid:

When manually editing my files for production deployment do I need to edit .htaccess or routes.rb to include the images and stylesheets directories so they''re still found like in my local development environment? I''m FTP''ing my "appname" directory to my hosting service to deploy. Unfortunately they don''t allow ssh/capistrano access and have no

Hi Yan, If you just need to access the env var which doesn''t change like SERVER_NAME, you should be able to access it directly using "request". However, if your env var is dynamicly set, you can try my way. I use mod_rewrite to proxy to Mongrel. In your httpd.conf (you need mod_header) RequestHeader set X_YOUR_ENV your_value And in Rails access it by
