Hi all R users Ive got a file that contains diffrent settings in the manor of: setting1="value1" setting2="value2" setting3="value3" setting4="value4" . . . What I want to do is open the file and change the value of a specific setting like wanna change setting4="value4" -> setting4="value5" and then save the file again.

I need to process some datasets where the configuration information was stored in .INI-like files, i.e., text files with sections like this: [Section1] var1=value1 var2=value2 [Section2] A=value3 B=value4 ... >From Google and other searches I haven't found any package, or function within a package, that reads .INI files into an R list, or other data structure. Any suggestions, or

Hi, The following [simplified] query works well, however a variation which includes parenthesis seems to fail, in that it returns hits which should be excluded by the NOT term. This is surprising because in this simple case, the parenthesis shouldn''t change the Boolean evaluation ... any pointers? Working Query: field1:value1 AND NOT field2:value2 Failing Query: field1:value1 AND

Background: FREEBSD 11.2 - SAMBA 4.10.15 Hello everyone, Good evening/afternoon/morning. I am trying to "reuse" the TDB database to my portal, where I want to store basically 3 information: IP address , Name, TimeStamp - where IP would be the KEY and "NAME,TIMESTAMP" would be the VALUE. I am using the tdbtool to insert/store data successfully (like the example below)

Hi, I would like to implement macro debug info support in LLVM. Below you will find 4 parts: 1. Background on what does it mean to debug macros. 2. A brief explanation on how to represent macro debug info in DWARF 4.0. 3. The suggested design. 4. A full example: Source -> AST -> LLVM IR -> DWARF. Feel free to skip first two parts if you think you know the background.

I''m new to rspec and looking for way to test a validation I added to a model. The test checks to see that if field1 has a value then field2 must be nil and vice versa. ------------------------------- When I did the rspec_scaffold it generated one test which worked before :each do @valid_attributes = { :field1 = "value for field1" :field2 = "value for

Hi - I have 3 fileds a user can fill out. They can fill out 2 of them or just one of them, for example. fill out these 2 fields: Field1 and Field2 Or fill out this field: Field3 In my model how do I use validates_presence_of for Field1 and Field2 or just Field3. I want to do something like this: validates_presence_of Field1, Field2 OR validates_presence_of Field3 So the user can fill out

Hello, In doing a series of non-linear estimations of a function which is a sum of a varying number of sinusoids, I would like to "autogenerate" the arguments needed by nls() depending on that number. For example, when there are two sinusoids: > nls( y ~ mu + A1 * cos(2*pi*f1*x - P1) + A2 * cos(2*pi*f2*x - P2), data = some.xy.data, start = list( mu=some.value0,

sorry to cross post to dev/users. -dev was not the best option ;-) Hi to all puppet masters: functionnality I need is quite simple: classes/ one .pp file per class, example: class mail-gateway { ...service/host/templates... definitions } -> this should set all that''s needed to setup a given system "rôle" in the system (installing packages, config files with variables

I want to add virtual fields in a model. table: field1 field2 I want to add field3 which is field1*2 + field2 I know tihs can be achieved in View, but I want it in model. Then I will pass this model to PagerRenderer to paginate. How to achieve this? thanks -- Posted via http://www.ruby-forum.com/.

To Whom It May Concern: I have an R package and want to put this package be part of R-project and available to anyone who is interested in. The R package is created for my paper, titled "Acceptance Sampling Plans from Truncated Life Tests Based on the Birnbaum-Saunders Distribution for Percentiles". The paper has been accepted by Communications in Statistics: Simulation and

Hi, How can I use a substring match as a condition in a subset command? Sth like this: subset(input, field1=="blah1" & field2=="blah2") # but now with substring match in field2 subset(input, field1=="blah1" & field3 *substringmatch* "blah3") I've tried with gsub, but it won't work: subset(input, field1=="blah1" &

> Do we really need to touch the AST? Or would it be reasonable to wire up the CGDebugInfo directly to the PPCallbacks, if it isn't already? (perhaps it is already wired up for other reasons?) This sound as a good idea, I will check that approach. PPCallbacks is only an interface, has nothing connected to it, but we will create a new class, which implement PPCallbacks, for macros. So we can

Say I have a csv file, each row contains several fields, one of them are whether the row is success. In history data, I have all the fields including the result of whether it is success. In future data, I only have fields without the result. For example: history data: Field1 Field2 Field3 Field4 ResultField 1231 CA TRUE 443 TRUE 23231 NC TRUE 123 FALSE

Hi, I''ve got an interesting one here :) I have a form with three fields : serial_number initial surname now, if serial_number is entered, it must be between 1 and 64000. If it''s filled in, the other two fields must be blank. If serial_number is left blank then the other two boxes must be filled. Any suggestions? -- Posted via http://www.ruby-forum.com/.

hi, read the API doc and made search with google but can''t get a precise explanation on how submit_to_remote work. can someone help on that? thanks

I believe that I may have found a bug in R. The top code sample gives an error as shown. However, by simply switching which field is initialized first as in the bottom code sample, it works as expected. This gives an error: a <- NULL a[["field1"]] <- 1 a[["field2"]] <- matrix(c(2,1), 1) Error in a[["field2"]] <- matrix(c(2, 1), 1) : more elements

Hi all, My current project brought forth the snippet below, which modifies in each row of a data frame a certain field depending on another field in the same row. Dealing with data of some 30000 entries this works, but is horribly slow. Can anyone show this newbie how to do this properly (faster ;0)? for (i in 1:nrow(dataframe)){ if

Hello, I wanted to parse some information from a text, where fields are tab separated. When I copy the text into an R session (under emacs) like: mystring <- "field1 field2 field3" the tab character is replaced by a single space! For ex, if I type mystring, I get: "field1 field2 field3" The tabs have disappeared!!! I checked with Python that the text I copied was tab

I await Luke''s node settings implementation with interest. At the moment however, I have this sort of ugliness: $site = $hostname ? { fred => "opsera", barney => "bedrock", default => "unknown site", ... } So I''ve knocked up this little function to use CSV files instead. Now I can just do: $site =
