Hi, Is there any way to estimate a DEPENDENT variable through a GLM/LM model? Suppose I have the linear model: y=a0+a1*x1+a2*x2 (a0=1, a1=0.6, a2=0.8, x1~N(1,1), x2~N(0,1)). The alphas and the auxiliary variables are given and I have to estimate y. The point is if I estimate it, let¹s say algebraically, I get high variances that do not decrease as sample sizes increases... Is the any other way

...other markup macros other than \dQuote and \sQuote, as errors or bad formatting may result." which doesn't indicate that \var should be handled any differently than any other macro, but the code makes me think that R is trying to pass the macro through to LaTeX.

Hi, Suppose I have an arbitrary function: arbfun<-function(x) {...} Is there a robust implementation of a numerical derivative routine in R which I can use to take it's derivative ? Something a bit more than simple division by delta of the difference of evaluating the function at x and x+delta... Perhaps there is a way to do this using D or deriv but I could not figure it out.

I've been trying to get Skype to run under wine, and although the speaker works great, the microphone doesn't appear to work. Microphone works great from linux. Anyone have thoughts on how to get wine to recognize my microphone? Running SuSE 9.0, wine-20040813-SuSELinux90.i586.rpm.

Hi, I have a data frame and want to merge adjacent rows if some condition is met. There's an obvious solution using a loop but it is prohibitively slow because my data frame is large. Is there an efficient canonical solution for that? > head(d) rt dur tid mood roi x 55 5523 200 4 subj 9 5 56 5523 52 4 subj 7 31 57 5523 209 4 subj 4 9 58 5523 188 4 subj 4 7

Dear Wiz[R]ds, I am deeply grateful for the help from Duncan Murdoch, Gray Calhoun, and others. We are almost there. For whatever reason, I can't change the symbol from a circle to a triangle in the upright posture plots. Any ideas? I have included the problem in full. # tritiated (3H)-Norepinephrine(NE) disappearance from plasma # concentrations supine and upright # supine...

I am looking at placing a system in an office with a central receptionist, and phones for each individual employee thereafter. Could I use a Snom 220 with additional keypads to view if the lines are in use by the other employees? Fred is in sales... A call comes into the receptionist and they transfer the call to Fred. The receptionist can tell Fred is still on the phone by viewing the assigned

Is there any way to disable image_tag''s automatic escaping of special html entities in it''s :alt tag? Example: >From the controller: @sale[''title''] = ''My Company Product&copy;'' In the view: <%= image_tag(''path/to/file.png'', :alt => @sale[''title'']) %> Output: <img alt="My Company

Y'all, I would like to have most of the variables in my function to be global instead of local. I have not found any references that tell me now to do that. If I have missed a reference please excuse me and tell me what I have missed. Thanks, Keith Jones

Hello everyone I am currently developing a web based R script editor. My idea is to pass the R script command as a string into the backend , then use the Rengine instance to parse the R script command and get the resutls. Do anyone know how to use Rengine instance to parse a R script String? if so, could you give me a small example (in Java)? i really appreciate. -- View this message in

Hi all! Do you know if there is any R function/package that can be used to estimate "logit" models with panel data and forecasting?

Hi all, Is there a way to do a matrix multiplication in a faster way? I am making a product of a matrix (composed of a lot of dummy variables) and a vector, and is there any way to make it faster? The simple X %*% y takes too long a time. I know using sparse matrix would help, but don't know how to do it i R. Thank you.

I don't find a function to print a string to file. Would somebody let me know what function I should use?

Hello R help members. I came across today with an article on Barnard's exact test (http://www.cytel.com/Papers/twobinomials.pdf), that is supposed to give a more powerful fisher.test - Because it doesn't assume that we know the row and column totals are in advance. Any pointers to such a function ? Thanks, Tal -- ---------------------------------------------- My contact information:

Hi, I've just been browsing for IDEs for R, see e.g. http://www.linuxlinks.com/article/20080413133953606/R.html It's probably highly subjective, but which free IDE is the best one around? For the Python language, I've always been using IDLE. I like the syntax highlighting and the syntax suggestions the user gets while typing a function name. Ideally, the IDE should run on any

Hi to all, I am looking for a randomisation procedure for a single matrix, including a possibility to set the number of randomisations and the to set the number of row and columns . Knut

Dear all, I tried once to create one variable called bip such that: bip <- cip + (1/f(cip))*fi(f,cip) And this was working. But now, doing the same thing I did before, the software shows me the following message: Error in f(x, ...) : unused argument(s) (subdivision = 2000) I have the variable cip and the variable bip should be created such that: Fn <- ecdf(cip) f <- function(x) {(1 -

I'm trying to run a game (Glider 4.0) with wine, but it gives me an error message: Code: error 201 at 0001:F4B0 Doing some searching, it seems that it might be related to a missing .DLL file, but if so, I'm not sure which one. Can anyone help?

How can I get the result of, e.g., poly(1:3. degree=2) to give me the unnormalized integer coefficients usually used to explain orthogonal polynomial contrasts, e.g, -1 1 0 -2 1 1 As I understand things, the columns of x^{1:degree} are first centered and then are normalized by 1/sqrt(col sum of squares), but I can't see how to relate this to what is returned by poly(). >
