I have a dataframe with many hundreds of survey records containing: tripid_nu, lineon, MuchOtherData, X1, X2, X3, X4 tripid_nu = identifier for each "Trip" {E.g. for EB MTA-901 leaving the first stop at 07:24} lineon = identifier for each of the stop locations Where X1 is the ratio (for each trip/stop combination) of some target number to the number of records.

I am fitting a cox PH model w/ 2 predictors, x1 = 0/1 treatment variable and x2=continuous variable. I am using natural splines (ns) to model the effect of x2. I would like to examine the estimated effect of x2 on the hazard. I have tried various approaches (below; let model.fit= fitted model using coxph in survival library): 1. The simplest method appears to be using termplot(model.fit).

I am using R to teach, and here are a couple of things that I thought would work didn't work. 1. I noticed the utility data(***,package=***) recently and like it very much, but unless I type in the whole word "package" I'll get an error in 1.4.0. For example, data(cats,package=MASS) works fine but data(cats,pac=MASS) doesn't. 2. drop1 doesn't seem to be as smart as

I needed to generate some data from the Inverse Gaussian distribution but it is not in R. A google search took me to http://www.maths.uq.edu.au/~gks/s/invgauss.html which contains the documentation for the d, p, r, q functions with a download link of the functions. The functions work fine in R. I am curious why the facilities are not included in R. Is it for legal reasons or just the

Hi, I followed the example in "Writing R Extensions" to create a shared object in Windows, using the command R CMD SHLIB X.cc X_main.cc This was encountered: ../src/gnuwin32/MkRules:155: warning: overriding commands for target '.c.d' ../src/gnuwin32/MkRules:143: warning: ignoring old commands for target '.c.d' ../src/gnuwin32/MkRules:171: warning: overriding commands

It was a real surprise, but a student in my class found that the function eigen is buggy. He traced to the problem from his inability of getting principal component analysis to work on his data.

Hi all, I am seeing a strange problem with Asterisk queue. I am not sure if it's my configuration which is wrong or there's something with Asterisk. I am using Asterisk 1.4.2 and i have a queue with one MGCP member. When i tried to call the extension number directing to the queue, the MGCP phone is not ringing. However, it is fine to call the MGCP phone directly. The strange thing is

Hi team, Is there a way to grab Kerberos specific log entries? Example: /Auth: [Kerberos KDC,ENC-TS Pre-authentication] user.../ I have tried using the kerberos class but nothing was logged when I specified a path. This is what I have on my smb.conf. /[global] ??????? log level = 1 kerberos:2@/var/log/samba/kerberos.log auth_audit:3@/var/log/samba/audit.log

I was trying to add points to filled.contour plots, but the points(...) function apparently uses a different coordinate system than the filled.contour(...) function; it appears that points(...) paints points where they would be if the contours were stretched over the whole plotting frame including the legend bar. Am I missing something or is it a "misalignment" in the code? BTW, I have

Hi, Jarkko: Thanks for the quick reply. I understand I can use ActiveRecord to specify the relation between the table as you have suggested, The part that I have trouble to understand is 1. Since I have a third table ProvWorkAtDept, do I need to specify this table somewhere when I define Provider or Dept? 2. If the provider view has both the provider name and several depts the provider

I'd like to create a data frame with components > jk$x1 [1] 2 > jk$x2 [,1] [,2] [1,] 0 0 I used to be able to do it with > jk <- data.frame(x1=2,x2=I(matrix(0,1,2))) But now I get a error message. Can I still do what I want? Thanks for any help. Chong Gu -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list --

I was hoping that the following specification postscript(file="fig.ps",height=2,width=4) par(mar=c(5,5,2,2)+.1,mfrow=c(1,2),mex=.6) would yield the same scaling effect as postscript(file="fig.ps",height=2,width=6) par(mar=c(5,5,2,2)+.1,mfrow=c(1,3),mex=.6) but the fact is that the 'mfrow=c(1,2)' yields smaller plotting frame and bigger font size.

Hello List! I asked this before (with no solution), but maybe this time... I'm trying to project a surface to the XY under a 3d cloud using lattice. I can project contour lines following the code for fig 13.7 in Deepayan Sarkar's "Lattice, Multivariate Data Visualization with R", but it fails when I try to "color them in" using panel.levelplot. ?utilities.3d says there

Hi, I'm new to 'R' and need some help on the "Load" command. Any responses will be highly appreciated. Thanks in advance! As per manuals, the "Load" command expects a binary file input that is saved using a "save" command. However it is required that we need to call the 'R' program from Java web application using RJava, and pass a string

I am not sure whether it is a design decision or just an oversight. When I ask for the standard errors of the predictions with predict(budwm.lgt,se=TRUE) where budwm.lgt is a logistic fit of the budworm data in MASS, I got Error in match.arg(type) : ARG should be one of response, terms If one is to construct a CI for the fitted binomial probability, wouldn't it be more natural to do

Just want to let whoever may be interested to know that the adapt function (package adapt) for multivariate integration may "cheat". A student here made a function f(x,y)=g(x)g(y) on the unit square and sent it to adapt, and adapt happily returned a value between 2 and 3 with an error estimate of the order E-11. He then used a 128-point Legendre quadrature produced by the gaussq.f

Dear List: I found an error when I called the 'gee' function. I cannot solve and explain it. There are no errors when I used the 'geeglm' function. Both functions fit the gee model. The project supervisor recommends me to use the 'gee' function. But I cannot explain to him why this error happens. Would you help me solve this problem? I appreciate your help. In
