I am trying to understand the concept of lexical scope in "An Introduction to R" by the R Core development team. I'd appreciate it if someone would explain why the following example does not work: q <- function(y) {x + y}; w <- function(x){q(x)}; w(2); According to the discussion of Scope on page 46, it seems to me that R will interpret the free variable x in q as the

The following command, issued from the DOS command prompt (running Windows XP), produces the intended result of a .csv file created by program.R: ?c:\program files\R\R-2.8.0\bin\Rterm.exe? --save < "c:\TEMP\program.R" However, when I create a file called Rbatch.bat that contains exactly the line above, and try to execute it (by double clicking or via the Shell command in an Excel

Does anyone know if any R package has a function that will conduct Hollander's test of bivariate symmetry? (Hollander, Biometrika, 1971) Either the exact test or an asymptotic version would be sufficient for my purposes. Thanks.

I'm trying to understand the use of recursive functions described on page 45 of An Introduction to R by the R core development team. A function is a list of expressions, which all get executed with only the last being assigned to a global variable, right? So if a function refers recursively to itself, it should simply start with the first expression and go from there. At least that is my

dear list, below is an edited version of my response to an r user asking me for explaining some issues related to r's evaluation rules. i find the problem interesting enough to be forwarded to the list, hopefully for comments from whoever may want to extend or correct my explanations. (i'd like to add that much as i'm happy to receive and answer offline mails, questions related to r

When I run a macro that uses RExcel, I get a dialog box that says "Microsoft Excel is waiting for another application to complete an OLE action." There is no error in the RExcel commands in the macro, of that I am sure. The box appears to be related to the inclusion of RunRFile commands. The macro will run through the second RunRFile command, but will not execute the

Hi, there is a line in TODO: "- sieve-cmu.c crash: i_assert(buf->used - 1 == part->body_size.physical_size); ". Yes, we've really seen this crash. Therefore we upgraded to dovecot-1.2.3 with dovecot-1.2-sieve-0.1.11 in order to use sieve plugin (i.e. not cmu-sieve). We use Solaris 10 on Sun servers, we don't use NFS. However, unfortunately, dovecot with sieve crashes

I just installed R 2.12.1, and when I went to run a few old programs with it, nothing worked. I got a ton of error messages saying such and such package was built before R 2.10.0 and needed to be reinstalled. These were not just warning messages, but error messages that prevent the programs from running when they were running just fine with R 2.10.1 For some of those packages, such as deSolve, I

Hi folks, Is there anywhere I can possibly get a model of the exam itself, maybe possible scenarios for the prac, etc? To people who have done the exam....any helpful hints ? Thanks,

Hi, I'm trying to create a function to return three dataframes for later use in a graphic so I want the return from the function to give me dataframes and with unique names relating to the variable they are based on. For example..... sub<-c("6-1a","6-1a","6-1a","9-2b","9-2b","9-2b","7c","7c","7c")

I''ve used Verdana heavily in many of my sites. My graphics designer likes it and so do my clients. There is a well-reasoned discussion that goes something like: - Verdana is bigger than any other font in default size - If a user doesn''t have Verdana, what they see may be way smaller than designed - Ergo, don''t use Verdana What is everyone else doing? 80+% of my site

Dear all, I recently read the book " R data preperation and manipulation using sqldf package" by Djoni Darmawikarta However, I have a problem with manipulation of dates using this package, I do not get the expected results. Do I need to install some packages to be able to subset the data by dates in sqldf? I am not getting Djoni Darmawikarta email address. Please see the practice

See FAQ #4 on the sqldf github home page.

Is there a package in R that can do a variability plot? A variability plot is a kind of categorized dot plot. (If there is a lot of data in each category, box plots are used rather than dot plots.) Usually, the categories are factor level combinations. All the dot plots appear in the same window; below the x-axis a hierarchy of factors shows which dot plot corresponds to which factor-level

Well, hi folks: I am still having this problem with ices crashing regularly. I have upgraded to todays cvs for ices and icecast hoping that would take care of it but no such luck. I am not sure just what is going on. It seems to happen fairly often which is not exactly making my listeners happy. I will include the relevant portion of the ices.log below. I would appreciate any suggestions

Buenas tardes, tengo dudas con el siguiente ejercicio que me han propuesto en un curso, no se si alguien podria indicarme como abordarlo, soy nueva en R y agradezco mucho su ayuda Identi car cuales son las variables que están contenidas en el data.frame. A continuación, transformar ese data.frame para que cada columna represente cada una de las variables. Usar los nombres Date, District y N.

My system is 5.6, with upgrades. I installed Java 6 from the Centos repository. It doesn't seem to have Java 7. I need the development package. How can I install Java 7 development safely? I imagine I will first have to uninstall Java 6. Thanks, John -- John J. Boyer; President, Chief Software Developer Abilitiessoft, Inc. http://www.abilitiessoft.com Madison, Wisconsin USA Developing

Thanks to all of you who are answering my dumb questions about my new CentOS instgallation. I modified /etc/hosts, as the hostname man page seemed to suggest, and rebooted. The hostname is still localhost. I want to change it to jjb-centos. I also want to change the domain name to abilitiessoft.com Thanks, John -- John J.
