Dear expert friends, I'm pretty young of this world and my question at your eyes can be petty easy. I'll need to change the name of the levels inside a column of my data-frame levels(ind.davis$Ageclass) <- c("adult", "Juvanile", "sub-adult") names(ind.davis$Ageclass) <- c("Adult", "Juvenile", "Sub-adult") that is what I

I''m not sure if I''m understanding this correctly. <SCRIPT LANGUAGE="JAVASCRIPT" TYPE="TEXT/JAVASCRIPT"> Event.observe(''mes_appearance_s0'', ''onchange'', function(e){ alert(''changed me!'') }); Event.observe(''headinjury'', ''click'', function(e){

Leonardo-- R-help can be a very useful resource. Some suggestions to use it well: 1. use an informative subject line, not "help" 2. include a "minimal working example:" a *little* data, the code that, with those data, reproduces your problem, and the error message that resulted. As to your particular question, at this point I can only guess, but for starters it would

I just upgraded my RH9 server with UW-IMAP to Fedora Core 2 and after a short try with Cyrus, I'm hoping to get Dovecot configured. My problem is getting Dovecot to recognize my old mbox mail folders. It correctly shows the INBOX contents from the /var/spool/mail/davis mbox. However, I also had a bunch of mboxes such as: /home/davis/Mail/Sent /home/davis/Mail/Lists/list1 Reading the

Here is my scenario when a client wants to resolve a name on my local network: CLIENT --> VPN --> SAMBA --> DNS The client is set up like so: DNS1 = ISP DNS1 (204.26.64.1) DNS2 = ISP DNS2 (204.26.80.3) WINS1 = my samba1 (10.10.1.5) WINS2 = my samba2 (10.10.1.8) This all _seemed_ to have worked 3 days ago for roughly 6 months but stopped suddenly without me doing anything. When the

...akpoints and fitting three distinct slopes, i.e. linear models. It does not, however give me Pr(>|t|) for the break point coefficients. I need to answer the question H:0 Beta0=Beta with a certainty metric, i.e. probability statistic. This is especially important for my, flat looking data class. davies.test() question: davies.test() only excepts lm() or glm() objects as input. If I run segmented to find 1 breakpoint instead of 2, I get a totally bogus answer. Without knowing the breakpoints, how is this test able to assess the proper breakpiont? It appears to only give 1 best breakpoint, which is...

Hi all. I''ve done a little google search, but doesn''t find anything (with "attachment_fu default path") that could help me in changing attachment_fu''s default path. My model: [audio.rb] has_attachment :max_size => 20.megabytes has_attachment :content_type => "audio/mpeg" has_attachment :storage => :file_system

R-helpers: Are there any ways to auto-generate R-friendly (e.g. will pass a compilation check) .Rd files given a set of .R code? How about GUIs that help properly format the .Rd files? Thanks! I want a basic set of .Rd files that I can update as I go, but as with most things my documentation typically lags behind my coding by a few days. --j -- Jonathan A. Greenberg, PhD Assistant Project

This is possibly the dumbest question I have asked ever, but how do you set ACLs on files within a ZFS filesystem? Trying to use setfacl(1) diverts me to the acl(5) manpage; well, I know that I need to use NFSv4 style ACLs, but where is the utility to do so? This is on Solaris 10 Update 2. Thanks, Ceri -- That must be wonderful! I don''t understand it at all.

Sir, I want to solve the equation Q(u)=mean, where Q(u) represents the quantile function. Here my Q(u)=(c*u^lamda1)/((1-u)^lamda2), which is the quantile function of Davies (Power-pareto) distribution. Hence I want to solve , *(c*u^lamda1)/((1-u)^lamda2)=28353.7....(Eq.1)* where lamda1=0.03399381, lamda2=0.1074444 and c=26104.50. When I used the package 'Davies' and solved Eq 1, I got the answer u=0.3952365. But when I use the function 'uniroot' to s...

An interview with Chief Marketing Officer of SAS Institute, Jim Davis. Here is an extract- http://www.decisionstats.com/2009/06/05/interview-jim-davis-sas-institute/ *Ajay -It is rare to find a major software company that has zero involvement with open source movement (or as I call it with peer-reviewed code). Could you name some of SAS Institute’s contribution to open source? What could be

Much thanks to all respondents. Since 1.9 is a very old version, I have the source code but am looking (close to begging) for someone who has a compiler to create an executable for me. I would be glad to send along the source , if you could compile and return an executable. This is the better request than to ask someone for their compiler. Thank you Paul Davis Sr. Business Development Manager

Hi, I have been using lm in R to do a linear regression and find the slope coefficients and value for R-squared. The R-squared value reported by R (R^2 = 0.9558) is very different than the R-squared value when I use the same equation in Exce (R^2 = 0.328). I manually computed R-squared and the Excel value is correct. I show my code for the determination of R^2 in R. When I do not set 0 as the

Hi all, I recently migrated our samba 3 domain to an AD domain using Samba 4 classic upgrade tool. Well, every seems to work fine since i'm still alive ;) . I promoted a Windows 2k8 box as a new DC of this domain and I transfer the 5 FSMO roles to it. Now I would like to demote the Samba4 DC but when I tried I got this message : # samba-tool domain demote ERROR: Current DC is still

Hi, The default value for lag.max in ACF implementation is 10*log10(N) There several publications recommending setting lag.max to: - N/4 (Box and Jenkins, 1970; Chatfield, 1975; Anderson, 1976; Pankratz, 1983; Davis, 1986; etc.) - sqrt(N)+10 (Cryer, 1986) - 20<=N<=40 (Brockwell and Davis) Why R uses 10*log10(N) as a default? Please, give me a reference to a book or article where the

I've had a play with this and, due to my own short-comings, remain none the wiser. In particular, I'm not sure what value of 'spar' is consistent with the magic lambda=1/1600 for quarterly data. I initially interpreted spar as lambda and tried setting spar=1/1600. This results in almost no smoothing while spar=1600 causes an error. The smooth.spline function seems to want

I'm trying to obtain the mean of the middle 95% of the values from each row of a matrix (that is, the highest and lowest 2.5% of values in each row are removed before calculating the mean). I am having all sorts of problems with this; for example the command: apply(matrix1,1,function(x) quantile(c(.05,.90),na.rm=T)) returns the exact same quantile values for each row, which is clearly

I am trying to get a prediction interval from a glm regression. With newdat being my set of values to be fitted, and glmreg the name of my regression, I am using the following code. predict(glmreg, newdat, se.fit = TRUE, interval = "confidence", level = 0.90) The problem is that I am only getting the standard error and the fitted value, not a prediction interval.
