I have the following function: Myfunc <- function(var1,var2,.....,varN) { ..... } In the above function I have a variable number of parameters (N>2). How can I count how many parameters have been entered? Any help appreciated Thanks Arno

I've the following problem: The below function runs a loop with regression analysis and stores F-Stat in a matrix. When I call the matrix elements (models[i,j]) in the function I get proper results, but when I try to call the same elements outside the function the matrix appears to be empty e.g when I call compt inside the function I get: 5 but when I call it outside I get: 1. This is the

I'd like to estimate time varying coefficients in a linear regression using a Kalman filter. Even if the Kalman Filter seems to be available in some packages I can't figure out how to use it to estimate the coefficients. Is there anyway to do that in R? Any help appreciated Thanks

Hello Fellow R Users,I have spent the last week trying to find a work around to this problem and I can't seem to solve it. I simply want to plot my GEE model result with 95% confidence bands. I am using the geepack package to run a basic GEE model involving nestling weights, to a Gaussian distribution, with "exchangeable" error structure. I am examining how nestling weight varies

Is there a simple function in R to get a moving standard deviation (i.e. for the last x samples)? My goal is to plot bollinger bands around a moving average for price data. I use kernel smoothing for the moving average. cheers and thanks! over and out -- doktora

The Blue Book allows the 'type' argument to be used in matpoints and matlines. matlines(x, y, type="l", lty=1:5, pch=, col=1:4) R-1.0.0 does not. Thus, type="h", "b", must be invoked thru matplot( x, y, type = "h", add=TRUE) For the sake of consistency with S, it would be nice to have matlines defined as: "matlines" <-

Hi, I am trying to specify four ticks (at 0,1,2,3 for the y axis) in a persp plot but the defaults overrule my specification and I obtain seven of them. Is it possible to gain full control over them in such a plot? Here is my code: matlines=matrix(c(1:7,3:9,3:9,2:8),nrow=7,ncol=4)

Hi all, I am struggling to compile a massive R code that I have written through some years, aiming to provide automated investment strategies to my Portfolio Managers. You may ask me why do I not rewrite the code in C or C++; the answer is it is really massive and that will take me lots of time. The pb is I will be moving from one team to another therefore I want to make it an exec program that

After switching to Asterisk 1.2.14 from 1.0.x, I encountered a very strange problem. There is no sound with Playback() or Background() commands. Even though, Asterisk console shows the file is being played when I call the extension (i.e. echo test), I can't hear anything. My echo test extension looks like this: exten => 600,1,Answer exten => 600,2,Playback(demo-echotest) exten

Based on reading 'rgb' documentation, I would have thought the following would have produced identical results. Can someone explain how to make this happen? I need to be able to specify an array of rgb values for the 'col' parameter. colnames.col <- c("black", "red", "blue", "green") colnames.rgb <- apply(as.matrix(colnames.col), 1,

Dear R-Users, I created the xyplot below using 10 groups (9 groups + 'Total' of all groups) with lty=1:10. I need the 'Total' to be a bold solid line (lty=1) where as the 9 groups just need to be distinguishable from each other. As you can probably see, when the group reaches CRA6 the lty starts from 1 again. I have tried to specify ten unique lines using lty=

I have a sample of lung capacities from a population measured against height. I need to know the 95% CI of the lung capacity of a person of average height. I have fitted a regression line. How do I get a minimum and maximum values of the 95% CI? My thinking was that this has something to do with covariance, but how? My other thinking was that I could derive the 0.975 (sqrt 0.95) CI for the

Hello, I'm wondering how to make it possible for the user to cancel the last entered digit, if he made a mistake. For example, a user calls and starts entering 1...2...4, then he should be able to press, lets say *, to cancel 4 and enter i.e. 3.

Please use a more meaningful subject. Some might take it as a spam and hit the delete button. Objects in the workspace are visible inside functions, but are usually not directly manipulated inside functions. When you modify an object in the workspace inside a function, what actually happens is a local copy is made, reflecting the modifications you made, and leave the one in the workspace

Hello R-Help, I've got a bit of an issue with WMF's. I am working on WindowsXP and outputting WMF format images. I then take the WMF format images and insert them in PowerPoint. I take the PowerPoint and convert it to PDF. The WMFs are nothing special. Just the typical x-y plot with a gray dotted grid added and a few matlines. The WMFs, when produced look great! They show

Dear R help, This seems to be a commonly asked question and I am able to run examples that have been proposed, but I can't seems to get this to work with my own data. Reproducible code is below. Thank you in advance for any help you can provide. The main problem is that I can not get the confidence lines to plot correctly. The secondary problem is that predict is not able to find my object

I'm using (Linux version) xfig() within a function and then simple matplot() and matline() plots. Although I do not define any bg or fg default color, sometimes all lines in the final fig file are green. The same code works as (I) expected if I use x11() or pdf(). This is what I'm doing: I open 2 devs: xfig() dev.set(2) layout(mat1) xfig() dev.set(3)
