Hello! I am trying to create an R optimization routine for a task that's currently being done using Excel (lots of tables, formulas, and Solver). However, otpim seems to be finding a local minimum. Example data, functions, and comparison with the solution found in Excel are below. I am not experienced in optimizations so thanks a lot for your advice! Dimitri ### 2 Inputs:

To whom it may concern: My name is Jillian Weinfeld. I am currently and undergraduate student at New York University and working at Mount Sinai School of Medicine doing research with epilepsy patients. At the moment I am creating a manhattan plot with my data set. After reading many forums and such, I have appropriately plotted my data, however, I wanted to see how I can change the colors of the

Hello, I am using odesolve to simulate a group of people moving through time and transmitting infections to one another. In Matlab, there is a NonNegative option which tells the Matlab solver to keep the vector elements of the ODE solution non-negative at all times. What is the right way to do this in R? Thanks, Jeremy P.S., Below is a simplified version of the code I use to try to do this,

Dear R users, I am trying to connect an Access database. The code I use is : channel<-odbcConnectAccess("Base") table.db<-sqlFetch(Base,"table",colnames=T) When I look at the table in R, the table imported lacks the first 41 lines, and the column names are the values of the 42nd record. Any hints ? I am working on a WinXP pro 5.1 box, R 2.5-0 compiled from source

Dear professor, I am currently using Design package and the cph formula for assessing multivariable analysis. I am tryng to get the C-index for my survival model based on Dxy coefficient.

Looks like a bug as I see tier-enabled = 0 is an additional entry in the info file in shchhv01. As per the code, this field should be written into the glusterd store if the op-version is >= 30706 . What I am guessing is since we didn't have the commit 33f8703a1 "glusterd: regenerate volfiles on op-version bump up" in 3.8.4 while bumping up the op-version the info and volfiles were

Yes Atin. I'll take a look.

Hi, I successfully configured dovecot using virtual users (and LDAP/AD). deliver is the LDA and verifies if the user exists (as recommended in the WIKI). However, the howtos in the Wiki say *nothing* about the case that the recipients should be verified *before* receiving the messages (prevent backscatter, ...). All configurations in the dovecot-Wiki (postfix and exim) just accept the mails

Hi, I would like to get started with RoR, since it seems to be a terriffic platform for Webdevelopment. However, I''m unsure what "level" you need to be on in terms of programming to get started? Best regards, Gustav -- Posted via http://www.ruby-forum.com/.

Hello, I'm introducing to you the decentralized cloud Cherrypop. Combining libvirt and LizardFS (as of now) it becomes a cloud completely without masters. Thus, any node is sufficient for the cloud to be up and therefore no wasted resources and no single point of failure. It's still pretty crude software but will work with some tinkering. Hope you try it and like it! For more

I want to do in-place edits on a list of data, but I''m having trouble getting the ID passed through to the controller. I use this in my view to create the field: <% for frame in @frames %> ... <%= in_place_editor_field :frame, :price %> <% end %> and this produces the following in my output: <span class="in_place_editor_field"
