similar to: Deploying: Not too sure what to do next??

Hi Everyone, I am trying to deploy my app on dreamhost and am following the quick start instructions on this wiki located here: http://wiki.dreamhost.com/index.php/Ruby_on_Rails I have followed all of the directions and can''t figure out why it is not working! I have been pulling out my hair for the past couple hours. Here is the sub-domain it is installed on:

Hi, I am following this "tutorial" on dreamhost to deploy with sub directories: 1. Upload your railsapp to ~/railsapp/. ** I have uploaded to /sharemyten.com/list/ (list is my railsapp folder) 2. Make all necessary changes mentioned in the QuickStart Guide above. ** Did this... 3. Create a symlink at the location you want the subdirectory that points to ~/railsapp/public/: $ cd

http://canadaonrails.com/ (when you hover over news and events) I''ve seen this implemented on a few rails sites now and I was just wondering if it is just a simple javascript from the prototype library. Does anybody know of any links on how to do this? Thanks in advance! -- Posted via http://www.ruby-forum.com/.

Hi Everyone, Would someone be able to do a huge favor for me and host a very small 1mb rails app for me?? I can''t get my hosting up and running yet and I really need it up and running by today for my professor to check it off. I only need it up for about two weeks. You will get a lot of karma points for it :) Thanks in advance!! Jordan -- Posted via http://www.ruby-forum.com/.

hi everyone, I hope someone can help me out with some active record basics? I''ve been banging my head for the past 4 hours and I can''t seem to get it to work. I am trying to add comments to a caption (just like how one adds a comment to a post in a blog). I seem to be able to read posts just fine from the DB, however, I can''t use the "recordComment"

Hi, everybody: I asked about this in r-help last week and promised a summary of answers. Special thanks to the folks that helped me understand do.call and pointed me toward plyr. We face this problem all the time. A procedure generates a list of data frames. How to stack them together? The short answer is that the plyr package's rbind.fill method is probably the fastest method that is not

Sorry My previous report is not detailed. In R, you will get this: > mylist <- list() > mylist[[1]] Error in mylist[[1]] : subscript out of bounds > mylist[[1]] <- c(1) Error: (list) object cannot be coerced to vector type 14 > mylist[[1]] <- c(1,2) > mylist[[1]] <- c(1) > mylist [[1]] [1] 1 I was trying to assigning c(1) to (mylist[[1]] <- c(1)) -- it seems

Hello I tried to define replacement functions for the class "mylist". When I test them in an active R session, they work -- however, when I put them into a package, they don't. Why and how to fix? make_my_list <- function( x, y ) { return(structure(list(x, y, class="mylist"))) } mylist <- make_my_list(1:4, letters[3:7]) mylist mylist[['x']] <- 4:6

No. I fixed that, the NAMESPACE file now contains: S3method("[[<-", mylist) S3method("$<-", mylist) It still does not work. I also created a print method (print.mylist) which did work out of the box, regardless of being in the NAMESPACE file or not. Could it be somehow in here (also in my NAMESPACE file): exportPattern("^[[:alpha:]]+") Or could it be that

Thank you all , very informative, never thought of doing a str( mylist[1] ) -----Original Message----- From: "Jeff Newmiller" [jdnewmil at dcn.davis.ca.us] Date: 06/15/2017 11:56 AM To: r-help at r-project.org, "Huzefa Khalil" <huzefa.khalil at umich.edu>, "ce" <zadig_1 at excite.com> Subject: Re: [R] is.null(mylist[1]) and is.null(mylist$a) returns

Hi - I have a list (call it 'mylist') with the following elements: (i) a function (call it 'myfunc' and expressed as 'mylist$myfunc') and (ii) a variable (call it 'myvar' and expressed as 'mylist$myvar'). Since I use mylist as a pseudo-class (I assign mylist to multiple different R objects), I would like to access the mylist R object from within the

Dear R users, Let's say I have a list with components being 'm' matrices (as exemplified in the "mylist" object below). Now, I'd like to subset this list based on an index vector, which will partition each matrix 'm' in 2 sub-matrices. My questions are: 1. Is there an elegant way to have the results shown in mylist2 for an arbitrary number of matrices in mylist?

Hi, I'm pretty new to R. I have an object (say a list) and I I have a function that I call on various columns in that list (excuse terminology if it's wrong/ambiguous). Imagine its like this (actual values are unimportant) and called mylist: >mylist A B 1 5 2 5 3 6 4 8 5 0 I have a function: foo = function(param){ #modify list A or B values depending on

Hi, some change during the last 10 days breaks code where slots of an object are changed globally: setClass("mylist", contains = "list") setClass("dummy", representation = representation( a = "mylist")) foo1 = function(i, x) { mydummy@a[[i]] <<- x ### change a slot } foo2 = function() { ### define an object mydummy <<-

I can define a list containing NULL elements: > myList <- list("aaa",NULL,TRUE) > names(myList) <- c("first","second","third") > myList $first [1] "aaa" $second NULL $third [1] TRUE > length(myList) [1] 3 However, if I assign NULL to any of the list element then such element is deleted from the list: > myList$second <-

Hi, I'm have a list of integer vectors and I want to perform an outer() like operation on the list. As an example, take the following list: mylist <- list(1:5,3:9,8:12) A simple example of the kind of thing I want to do is to find the sum of the shared numbers between each vector to give a result like: result <- array(c(15,12,0,12,42,17,0,17,50), dim=c(3,3)) Two for() loops is the

I find that the str function is more helpful for understanding the difference between a null list and a list containing a null list than the implicit print function call that the interpreter invokes when you enter an expression at the console. str( mylist[1] ) -- Sent from my phone.

Hi, Try > is.null(mylist[[1]]) [1] TRUE Notice the double square brackets. From: ?`[` "The most important distinction between [, [[ and $ is that the [ can select more than one element whereas the other two select a single element."

Dear List, Let's say I have a list whose components are 2 matrices (as exemplified in the "mylist" object below). I'd like to create a list with components being 4 matrices based on an logical index vector. is there a way to simplify what I'm doing to obtain the results in "mylist2"? I'd like something that would work on an arbitrary number of elements in

I have this awkward problem with trellis (lattice). I am trying to generate some plots through loops but the .eps file is empty. When I generate them in a list and print them outside the loop all is fine. this is an example below:( nothing shows up in foo.eps, but all show up in foo1.eps) R vesion 2.0.1, lattice version 0.10-16, on a debian 2.6.8-1 kernel.
