I am working on a site which tracks "ferms" (read: widgets)... each ferm belongs to one company, one company can have many ferms. One company can also have many users with different access priveliges, and company administrators would invite other users to access the company''s site. Also, one user can belong to different companies and perhaps have different access at each

I have dose response data analyzed with the package 'drc'. 'summary(mymodel)' prints my kinetic parameters. I want that text in an ASCII text file. I want to get exactly what I would get if I copied and pasted from the terminal window. I've read the documentation on data export to text files here:

I try to fit reaction kinetic data to a given hypothetical model consisting of 3 ODEs. After some reading in Bates/Watts and the literature cited there (e.g. Jennrich/Bright) I looked in R for functions that support the use of the matrix exponential method. Until now I used for a similar (but simpler) problem the nls package and fitted against the the parameterized solution function. But this

Hey guys, Trying to figure out how to do something like the following: class Child belongs_to :parent has_field :some_field, :through => :parent end class Parent has_one :child attr_accessible :some_field end child.some_field #=> parent.some_field child.some_field = value #=> sets parent.some_field = value I can of course accomplish this by adding custom accessors

Hi, this is my R-Script library(pls) file <- "C:\\TXT\\brix.txt" d <- as.matrix(read.table(file, header=T, sep=",", row.names = NULL)) plsdata <- data.frame(NIR=c(1:nrow(X))) plsdata$NIR <- I(d[,3:603]) plsdata$Brix <- d[,2] results <- plsr(Brix ~ NIR, data=plsdata) after the last string i have this error > results <- plsr(Brix ~ NIR, data=plsdata)

Hi all - I've been working on a lite ORM and database abstraction package for R. Formatting complex queries by hand has always been an error-prone hassle, so I've tried to do away with that as much as possible, instead, using R objects to represent elements of a database system (statements, clauses, operators, functions, fields, tables, etc.). R5 classes have made the development of this

Hi, When I try a net logon from Windows 7 64-bit Business (don't have any other Windows machines), I get "The trust relationship between this workstation and the primary domain failed". The discussion I've found around the Web regarding this error message seems to be only in the context of the 30 day password expiry issue, where the solution is to simply rejoin the domain.

I''m trying to validate a record before save. I''m using one controller in this case furnii where I have all my calls. The problem is that, the form containing the field I''m trying to validate resides in the furnii views. I tried to add validates_presence_of :content (the field name) in both the furnii model and the ratecomment model but it does not work. I know there

Hi Could I know on i386 RELENG_7, what Makefiles install following header files: 1) /usr/include/bsnmp/snmpmod.h 2) /usr/include/bsnmp/snmp_mibII.h 3) /usr/include/bsnmp/snmp_atm.h Appreciate your reply very much. Kind regards Unga

Hi, I was trying to run the example of Indomethacin kinetics from the book: ## From Pinheiro/Bates, Mixed-Effects-Models in S and S-Plus, ## Springer, Second Printing 2001, Section 6.2 library(nlme) plot(Indometh) fm1Indom.nls <- nls(conc~SSbiexp(time,A1,lrc1,A2,lrc2), data=Indometh) summary(fm1Indom.nls) plot(fm1Indom.nls,Subject~resid(.),abline=0) ## .... the last plot command gives me the

I spent a solid two weeks trying to make a RH 9 with Samba 3 PDC operate the way I wanted it to in a domain that includes an NT 4.0 PDC. Early this morning, the NT user dogbreath belonging to the NT group mongrels was able to log into the NT PDC, map to the big_ugly_dogs share on the Samba machine, copy a file there, open it in OpenOffice 1.1.0, edit it, save it and then delete it. All of this was

Hello, I am trying to make a plot of the rates of an enzyme against three different protein concentrations (there are 45 rates in total and split up into 3 groups of 15, each receiving one of the 3 protein concentrations). When I enter the following code I instead get 3 separate boxplots for each of the three different protein concentrations ... plot(rate ~ ferm, data=LDH, col=LDH$rate,

Hello You must add first: vlan (tagged) to eth2 eth2 interface is not tagged by default and not know vlan-s . It is like a cisco if you have 24 ports in cisco by default all ports are in vlan1. if you want to do trunk (with vlans) you myst add (vlans) to this ports (tagged or untagged) So you can compare that all interfaces in linux by default are in one vlan(but not tagged). (only for

Hello everybody! Since the update from 6.2-STABLE to 7.0 I'm encountering problems with the temperature of my Thinkpad X60s. Under heavy load, e.g., make builworld or compile gcc or...

Dec 29 01:53:13 delta1 syslogd: /dev/:0: No such file or directory Dec 29

Is there any R package that implements the same capability of MatLab toolbox called SimBiology ? We are expecially interested in protein-protein interactions and network analysis. As far as I know SimBiology implements a system of ODEs reflecting the kinetic chemical reactions. We would be more interested in stochastic simulations. Thank you in advance. Maura tutti i telefonini TIM!

Hello, I'm suffering a estrange problem in a WinNT-Samba3 environment. I have two servers: WinNT4 (PDC of domain A-DOMAIN) and Samba3 (PDC of B-DOMAIN). A-DOMAIN and B-DOMAIN trust each other (I had followed the procedures described in HOWTO Chapter 16 successfully). The problem arises when I assign permission in WinNT server's folders (A-DOMAIN) for users in the Samba domain (B-DOMAIN).

I''m having a bit of difficulty when testing my models, I''ve read a few times the testing chapter in Agile web development with rails and at http://manuals.rubyonrails.com/read/chapter/27 but i''m still unsure of what I should be testing. Firstly I''d like to be able to test things like my email validation using lines such as assert User.new(:email =>

Hello, >From smb.conf man page: "You may find that on some systems Samba will say "Unknown socket option" when you supply an option. This means you either incorrectly typed it or you need to add an include file to includes.h for your OS. If the latter is the case please send the patch to samba@samba.org <URL:mailto:samba@samba.org>." I'm exactly in that
