Hi, I cannot seem to find out how to pass in a value to a partial. Can anyone help me? What I am doing(in the code below) is calling a function in my controller called setobject. This function just redraws the partial. I want to be able to change the value @objectname, redraw my partial and have it be able to use that value. The first the page is drawn it works, but when i call setobject it

Context: I'm relatively new to R and am working with very large datasets. General problem: If working on a dataset requires that I produce more than two objects of roughly the size of the dataset, R quickly uses up its available memory and slows to a virtual halt. My tentative solution: To save and remove objects as they're created, and load them when I need them. To do this I'm

I am still struggling to map a character string to an object name and vice versa in R. I thought the as.name() function might work, but observe the following behaviour ... > attach(warpbreaks) > levels(tension) [1] "L" "M" "H" > levels(as.name("tension")) NULL > objectname<-as.name("tension") > objectname tension >

Hello, I get this error trying to load some data from DB. I''m using Rails 1.2.2 on Fedora Core 6 and Sybase adapter. This worked fine when application run under Rails 1.1.6 but now I''m migrating to 1.2.2 and have some problems.

Dear List, I have a series of nested loops with the structure shown below, and I am struggling to figure out how to divert output to folders created with dir.create() within the loops. What I need is for the output to end up as topNameK/subNameL/objNameM.pdf; what I get instead is a series of directories topNameK/, directories subNameL/, and files objNameM.pdf, all in the working directory. Any

Hi folks, I'm trying to figure out how to get summarized data based on multiple columns. However, instead of giving summaries for every combination of categorical columns, I want it for each value of each categorical column regardless of the other columns. I could do this with three different commands, but i'm wondering if there's a more elegant way that I'm missing. Thanks!

Hi; It's been a while since I controlled my own server and I'm rusty. Trying to install mysql yum install mysql All looks well. Here's what happens: [root at 13gems www]# mysql ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) [root at 13gems www]# mysql -u root -p Enter password: ERROR 2002 (HY000): Can't connect to

I have a simple dataset of a numerical dependent Y, a numerical independent X and a categorial variable Z with three levels. I want to do linear regression Y~X for each level of Z. How can I do this in a single command that is without using lm() applied three isolated times? -- View this message in context: http://r.789695.n4.nabble.com/Linear-regression-on-several-groups-tp2322835p2322835.html

Dear all, I am trying to do weighted regression using lm function in R. However, I have a question why the results from 1) lm(formula = Y~aX, weight = w) 2) lm(formula = wY~waX) are different. Aren't they supposed to have the exactly same result? Below are the R code to see difference in regression results MatY <- c(0.15,0.42,0.31,0.22) MatX <-

Hi; I installed yum install mod_python and all went well. So I thought it would be appropriate to reboot apache apachectl -k restart and it appeared well but the pages don't load (they hang). Nevertheless, # ps wax|grep httpd 12179 ? Ss 0:00 /usr/sbin/httpd 17698 ? Z 0:00 [httpd] <defunct> 17703 pts/0 S+ 0:00 grep httpd So what gives? Please advise. Victor

Hi; I'm new to Dovecot and Postfix. I'm trying to enable these with MySQL support and postfixadmin. I've got all those services up and running (finally!); however, I can't figure out if the emails are being received and/or stored. I'm pretty sure Postfix is receiving them because I dealt with certain errors and they're now gone. Here's some data: Dovecot ver. 0.91

Dear R users, is there any possibility to get an object-name completion within the R command line (UNIX-version of R). As I got to know from the FAQ that this is possible from within Emacs (ESS), but without using Emacs?

Our outsourced IT department has decided to use white listing on the firewalls for outbound ftp. I was given a list of sites our lab had accessed via ftp and eventually tracked them down to Linux machines running yum. They are all CentOS 5 or 6 with a smattering of 7. It is impractical to list all the possibilities since they change on a regular basis. Also any 3rd party repos we need are

Thanks to everyone who responded to my first set of questions. Not only did I get my questions answered but I improved my code and learned a couple new things. I think I prefer the mailing list over IRC... easier to follow :-) I have some more questions if you don''t mind. Some are Rails related and some are Ruby related. 1) This is concerning displaying error messages. I am assuming

Under help(matrix) it is written: 'is.matrix' tests if its argument is a (strict) matrix. It is generic: you can write methods to handle specific classes of objects, see InternalMethods. Further down, under "Details", the meaning of "strict" is explained more explicitly: 'is.matrix' returns 'TRUE' if 'x' is a matrix

So a little background, in my domain we have 2 domain controllers, the main (A Windows Server 2008 R2), and a secondary that is was recently migrated from Server 2003 R2 to Samba. Both domain controllers are offsite so we use OpenVpn to connect them, dns is set to the samba domain controller then the Windows server, this is due that the samba domain controller is up 24/7 while the Windows is only

I use the ff-package for large data and have good success in session. To ensure my data is available for the next R session, I save my workspace and use the /ffsave/ command to archive my large data objects. Syntax is simple: > ffsave(file="~/path/archiveName", list="objectName") when I have multiple files to save, the list is expanded using c(). When I start a new R
