Is there a way to call a method if I only have a string that contains the method name. For example: @methods = [''method1'', ''method2'', ''method3''] @step = 1 # I want to call method2 which has a definition in this class -- Posted via http://www.ruby-forum.com/.

What would be the best way to create a form select dropdown box and upon "submit" have it directly go to a controller method view? I have something that somewhat works, but I think there is probably a much easier way to do it. As of now, I have the dropdown list which when the form is submitted is handed to a controller method which basically I have my dropdown box: <%=

I'm trying to find a clever way to re-map data from a database query into a data.frame. Querying a database often returns a table (data.frame) like this: GeneID MethodID Value 6 1 123 6 2 456 6 3 987 7 1 234 7 3 432 8 2 190 8 3 34 8 1 864 Note that GeneID=7 doesn't have a value for MethodID=2. Note that GeneID=8 doesn't have the

hi ,I am writing a soft package based on R. But when I try to read a configure file showed as below. How can I read the parameter in this text file. How can I read the parameter into each variable in this file ? configinfo<-scan(file(configfile),ok=TRUE,n=-1) scan seems need every line have same column ? configinfo <- readLines(configfile,ok=TRUE,n=-1) methodnum <-

A question about the layout of structs: I decided to make my vtables out of structs rather than arrays. In other words, instead of being a table of opaque pointers, I decided to individually declare each entry with the correct type for that method. I figure that the various optimizers could do a better job if I preserve the type info. OK, so we come to the issue of inheritance: Suppose I have

Hello, I am frastruated with this graph, just cannot get what I need. Thank you for any suggestions or help. I really appreciate it. I wrote the following code, but there are 3 problems 1, the red line is added on the graph but without any marker on the y-axis. I want to display the number '.1361' on the y-axis. So people can easily tell 'method 2' gets a constant estimate, which

I saw in one of Dave C.''s comments to a ticket that "our current plan is to deprecate the mocking framework." I hadn''t heard anything about that, but then again I haven''t paid super close attention to the list. Are we planning on dumping the mock framework in favor of using Mocha (or any other framework one might want to plug in?). Pat

Here is a new version of my partial auth patch against the April 24, 2001 CVS image. It fixes a couple of things (thanks to Karl M <karlm30 at hotmail.com>), and includes support for hostbased auth. It's still not pretty, but it works. 2 things Karl mentioned aren't fixed: - auth methods are still hard-coded into servconf.c. Fixing this would require a lot of work, and all the

Dear all, I want to compare the efficiency of 2 methods in extracting proteins from algal samples. I collected 6 independant algal samples and I extracted 3 by the method 1 and 3 others by the method 2. So I have 2 groups of 3 samples, that are not paired. I would like to know if the results obtained by these 2 methods are significantly different, I hope method 2 to be more efficient than method

JavaScript doesn''t (yet) have a notion of classes. Prototype.js just adds a suitable convention for implementing them. It provides a way to create a new class by extending a base class using Object.extend, but it doesn''t handle method inheritance. There are ways of doing implementing this through traversing the chain of prototypes, but I''m not sure they are

Hi, I developed an app with cetain controller names. Now that the app is catching up I''m trying to change the controller names to be better aligned with the business. This is what I have now. http://localhost/foo/method1 http://localhost/foo/method2 http://localhost/foo/method2/a http://localhost/foo/method2/a/b http://localhost/foo/method2/a/b/c http://localhost/foo/method3 I would

Hello, I'm using ROCR to plot ROC Curves and I want to automate the saving of plots into PNG files using a custom function. My data frames are named like test1, test2, test3. Each data frame has three variables: method1, method2, goldstandard. Right now, for each plot I have to run: png('test1_method1.png') plot(performance(prediction(test1$method1, test1$goldstandard),

Quick question: If I want to schedule different worker methods defined in the same worker to trigger at different times, is this possible? Would the following scheduler yaml work? :schedules: :foo_worker: :worker_method: method1 :trigger_args: 0 */10 * * * * * :job_key: some_key_1 :foo_worker: :worker_method: method2 :trigger_args: 0 */15 * * * * * :job_key:

Hello, I have a problem with a tklistbox. The user should be able to choose one out of two calculation methods needed for further calculations. My r-script for that purpose looks like that: require(tcltk) tt<-tktoplevel() tl<-tklistbox(tt,height=4,selectmode="single",background="white") tkgrid(tklabel(tt,text="select method for LAI

Hi all: My data:data(sleep) If I wanna calculate each group's extra,what I can do is: #method1 attach(sleep) mean(extra[group==1]) mean(extra[group==1]) #method2 result<-matrix(,0,2) g<-split(sleep,sleep$group) for(i in 1:length(g)) { result<-rbind(result,data.frame(unique(g[[i]]$group),mean(g[[i]]$extra))) } colnames(result)<-c("name","mean") But the above

Hi everyone thanks for the replies. The issue was NOT a font problem; I deliberately chose ll1 and l11 as examples of easily confused variable names (evidently these were too easily confused ;-). The code snippet was written as intended, and increment() contained a deliberate, highlighted, bug. I was asking for guidance on avoiding/finding this sort of coding error. That was why I wrote

1. I have seen examples similar to the following: image = MiniMagick::Image.from_file("input.jpg") image.resize "100x100" image.write("output.jpg") I''m assuming that image.resize is a method. Is there any significance to the fact that the argument for that method is not enclosed in parenthesis while the other are? Examples seem to be consistent --

While the spirit of BDD is to spec first and code second, many of us have legacy code. Worse, some of us have legacy code without very good coverage. Recognizing that *I* have such code, I created a script that grinds through your .rb files and creates placeholder specs for each public method. While it is more sensible to spec behavior of code function than of individual methods, this

How does one properly get find_all to grab the data from the DB table ordered by a specific column? For example: @anglers = Angler.find_all This code gets all the angler records and they are sorted in order of the id field which is of course set as a primary key in the DB (mysql). I''d really like to pull the data from the DB sorted in the order of another field, for example

I see a rich set of graphic device functions to redirect that output. Are there commands to redirect text as well. I have a set of functions that execute many linear regression tests serially and I want to capture this in a file for printing. Thanks, Stan Hopkins [[alternative HTML version deleted]]
