Maybe there is a great website out there or white paper that discusses this but again my Google skills (or lack there of) let me down. I would like to know the best way to export several doubles from a function, where the doubles are not an array. Here is a contrived function similar to my needs: multipleoutput<-function(x) { squared<-x^2 cubed<-x^3 exponentioal<-exp(x) factorialVal<-factorial(x) } Thanks again for all your help.

This is admittedly a contrived example, but... data(housing, package ="MASS") x <- housing$Type + housing$Sat match(x, unique(x)) Hadley -- http://had.co.nz/

...LDAP service in AD and I understand the complexities of the extensions AD has put on to its LDAP however; without the ability to auto discover users and groups it's a management burden for me to implement some form of continuous sync to massage data from the central campus LDAP to Samba4. I can contrive methods and fortunately Marco has given me a great lead but it still seems overly complex. This is why I was looking into auto discovery / auto creation of users and groups via an external authentication request. At least then the users would exist if they successfully authenticated. Obviously tha...

I am testing 'qr' with an admittedly contrived matrix and I am getting different results than I am from another package. The matrix that I am using is: x <- matrix(seq(.1, by=.1, length.out=12), 4) So the whole test is: x <- matrix(seq(.1, by=.1, length.out=12), 4) qr(x) And the output from 'R' is: $qr [,1]...

I have the following contrived code in package format. On Solaris and Mac OS X, code runs just fine. On Windows, it crashes the R environment with the "Send Bug Report" dialog. I tried R 1.8.1 (Win2K) and R 1.9 (WinXP) binaries with the same result. PCs otherwise appear properly configured for creating R packages. Any...

Granted, it's somewhat contrived and I'm not 100% sure if it's legal. Once there are pointers, there is little that can be done without knowing at least something about what they point to. -Krzysztof -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, hosted by The Linux Foundation

...fter *much* digging and playing around, I finally figured out how to unit test instance variables that are created by actions. It was more difficult than I expected. It seems like there should have been a more straight forward way to do this. Can someone enlighten me? A simplified and somewhat contrived example of what I am current doing: Thanks.

I'd like to get this in, but would really like to do a profile first. Could you please include a testcase?

Based on my understanding of her design, following is one obtuse motivating example: -------------------------- class A; class B; int foo(A* p, B* q) { p->a_int_field = 2; q->another_int_field = 3; return p->a_int_field; // !!!!! } ---------------------------------- the *-statement can be optimized into "return 2" if optimizer can prove type-A does not include

...en running on and off about 12 hours now and the resident memory of the above process is already at 7.5G and continues to grow slowly. If I stop the test script the memory stops growing, but does not reduce. Restart the test script and the memory begins slowly growing again. This is obviously a contrived app environment. With my intended application load it takes about a week or so for the memory to get high enough to invoke the oom killer. Is there potentially something misconfigured here?

I would like to replace a few varaibles within a data frame. For example, in the dataframe below (contrived) I would like to replace the current housesize value only if the Location is HSV. However, I would like to leave the other values intact. I tried "ifelse", but I don't really need the else condition. test_data2_df<-data.frame(Variables=c("SQR Footage","SQR F...

...ble problems. As a toy example, consider classes A and B and associated methods as defined below. I use a validity method for A to complain about negative values, and an initialize method to "correct" small input values. B should simply extend A by adding an extra slot. The example is contrived, but it illustrates a key behavior that I also encounter in my real code: setClass("A", representation(x="numeric")) setClass("B", representation(y="character"), contains="A") setValidity("A", function(object) { message("star...

...associations. First, let me say that I''m a big fan of :include for reducing the number of SQL calls. There are times when I wish it could go more than 1 step away from the parent object, but I kind of understand why it can''t. Now, on to my "discovery"... Completely contrived example follows: I have the following Models: class Author < ActiveRecord::Base has_many :posts end class Post < ActiveRecord::Base belongs_to :author has_one :category end class Category < ActiveRecord::Base belongs_to :post end There are many authors in the database th...

...which has 5 preceding empty intervals, so its adjusted count would be 1/6. Similarly, the second one would be element 8 (3), which has 1 preceding empty interval, so its adjusted count would be 3/2. Can somebody please provide a hint to implement such a weighing scheme? I thought about some very contrived ways to accomplish this, involving 'which' and 'diff', but I sense a function might already be available to do this efficiently. I couldn't find relevant info in the usual channels. Thanks in advance for any pointers. Cheers, -- Seb

...exception is thrown. I haven't implemented a test case that reproduces the problem, but I will do so. (I've verified the problem and the fix in the scope of a much larger system) I'm open to suggestions as to how best to test it, I'm currently thinking of trying to create a highly contrived situation to force exception tables to be written at the end of a buffer that won't be long enough. ============================================================================= michaelMuller = mmuller at enduden.com | http://www.mindhog.net/~mmuller ------------------------------------------...

...on of the openblas package is the latest currently available for 14.04 LTS from the official ubuntu repository. 14.04 LTS is "supported" by Canonical until 2019. Also, I'm just confirming that I can repeat it. It's not an issue for me as it's never happened other than the contrived example. If someone brought it to my attention, I'd probably follow your original though and ask them if they really wanted the determinant of an unassigned matrix as it sounds like not a useful thing to do. Using rnorm to initialise the matrix works fine. I'd suggest the OP pursue it w...
