Dear R users, I am happy to announce that the R package 'productivity: Indices of Productivity Using Data Envelopment Analysis' is now available on CRAN (https://cran.r-project.org/package=productivity). Productivity allows computing various transitive measures of productivity and profitability, in both levels and changes. In addition to the classic Malmquist productivity index,

Dear useRs, I am trying to build my package (nonpareff) which deals with some models of data envelopment analysis. The building worked well, but checking complains when it tests examples. Zipped nonparaeff.Rcheck is attached. Following is the log. --------------------------------------------- arecibo:tmp arecibo$ R CMD build nonparaeff/ * checking for file 'nonparaeff/DESCRIPTION' ...

Nicolas, Thank you for your response. I had tried that before and it didn't work. I am trying to look up the route for a dialed number, so its a full E.164 number. Please see my query below when I try to look up the route for a USA number; mysql> SELECT * FROM routes WHERE "^13237309880" RLIKE pattern ORDER BY LENGTH(pattern) DESC;

Hello, I am very new in R so I am so sorry for this question. I have the Barro-Lee data set which contains 98 countries and I want to run the regressions only for the Latin America countries, so what do you recomend? How can I delete all the other countries or how can I select the countries of Lat. Am. thank you this is the list of countries SHCODE COUNTRY NAME WBCTRY

Hi, I''m trying to deploy my app using FastCGI, and I have a problem. The application works correctly in either FastCGI or CGI mode (toggling between dispatch.fcgi and dispatch.cgi in my public/.htaccess file) except that under regular CGI, my ENV hash is correctly set, but under FastCGI, the ENV hash is completely empty. I thought that environment variables were automatically passed

Dear all: Does anyone have any suggestions on how to make a spatially explicit landscape with spatial autocorrelation in R? In other words, a landscape where all cells have a spatial reference, and the environment values that are closer in space are more similar (positive spatial autocorrelation). Thank you, Laura

Hi, Last night I tried to figure out if borland's linker was already unusable on Wine (seems it's working right now :) ), but I had trouble getting the path working. Everything I put in [wine] / "Path", it's not getting accepted. Reading the documentation it should be put to something like "C:\Windows;C: \Windows\System" at least, but Also if I put it to

Here is a simple example to show what I mean: f1 <- approxfun(1:3, 2:4) dump("f1", file="") which yields (in current development snapshot; other versions are conceptually equivalent) "f1" <- function (v) .C("approx", as.double(x), as.double(y), n, xout = as.double(v), length(v), as.integer(method), as.double(yleft),

wrapper <- function(){ Sys.setenv(TMP="A") print(Sys.getenv("TMP")) .C("c_fun") } As the example above, I hope to set an env var $TMP inside the R function "wrapper", which affects the functionality of the C function call "c_fun". Also the print line shows that $TMP is set to be "A", but the function call of "c_fun"

Hi, I recently had some difficulty getting an embedded R session running on Windows, due to the way that R Sys.getenv works, which I would consider a bug. Even if you do not agree, then you may still want to document it for future users who might be bitten. As outlined in R-exts (?8.2.2): http://cran.r-project.org/doc/manuals/r-release/R-exts.html#Calling-R_002edll-directly R_HOME/bin needs to

Hi, I see some weird behavior when loading a specific dataframe after changing the value of an enviroment variable using Sys.putenv(). Alas, I can't reproduce it from an arbitrary dataframe.

Environment variables set with Sys.putenv() "disappear" spontaneously (and somewhat randomly) when I load large datasets. This was reported in R-help by Dave Kane on June 4, 2001; I have not seen any further discussion. I'm not sure if I can report it as a "bug", since it is not entirely reproducible. Could someone try this and see if you have trouble too? The following

Having just discovered "Task Views" I see there isn't one for ecology/environmental science. I don't have the expertise to help with this, but I think it would be a very useful addition if there was any person (s) on the list willing to help create such a Task View. I am sure the maintainers of the Task Views will pick up on any responses to this post from volunteers. I

I am having an issue passing a command through ssh which uses an environment variable. I would like the environment variable to be read from the remote host, but it is being read from the local host. For instance: ssh rhost ls -lm $WWW_HOME $WWW_HOME is set as /usr/www on local but /var/www on the remote so it is being read as : ssh rhost ls -lm /usr/www and I'd like it to be ssh rhost
