Hi Does anybody know of any R packages under Windows to produce video files from a sequence of R graphs -- e.g. in .wmv or avi format? Thanks David

Hi Is there a way to specify the location on the screen where a new graphics device opens, for example with a call to win.graph()? I'm using R 1.7.0 on Windows XP. Thank you. Regards, David

Hi When I start an instance of an R stats server using the R(D)COM RExcel Addin by Thomas Baier, it appears to start the server in a temporary directory. Is there any way I can change the directory...

Hi Does anyone know of any R routines to send emails from R, under Windows? I thought about writing such a facility using the R(D)COM package to drive e.g. MS Outlook, but I don't want to...

Hi Does anyone know of any R code for estimating a *multivariate* state space model using a Kalman filter where the output matrix H(t) is time-varying but predictable (i.e. measurable w.r.t information at time t...

If A is your matrix try: cnames(A) = paste("X", 1:ncol(A), sep="") -----Original Message----- From: David Andel [mailto:andel at ifi.unizh.ch] Sent: 08 July 2003 17:23 To: R-Project Subject: [R] how to rename rows...

Sorry, that should have been "colnames" rather than cnames; i.e.: colnames(A) = paste("X", 1:ncol(A), sep="") -----Original Message----- From: David Andel [mailto:andel at ifi.unizh.ch] Sent: 08 July 2003 17:23 To: R-Project Subject...

Hi I am using the heatmap function in package mva to look at large correlation matrices visually. Is there any way to "flip" the output of heatmap plot left-right so that, if presented with a correlation matrix, it plots...

Hello I am using Duncan Lang's RDCOM Client package (available on omegahat.org) under R 1.7.0 and Windows XP Pro. Is this the right forum for questions about this package? In case it is, here is my...

Hi I am using package RODBC version 1.0-1 under R version 1.7.1 on Windows XP Pro. I am having problems writing a new table to an (Excel) database using sqlSave. I connect to an empty Excel...

Have you tried win.metafile (I'm assuming you are using Windows)? E.g. win.metafile(file = "c:/test.wmf") plot(rnorm(100)) dev.off() WMF is a vectorised format (unlike jpeg or bmp) so should produce nice scalable graphs...

Sure -- just use a Lagrangian multiplier to bring the constraint into the objective function and then use a QP routine like quadprog (in the quadprog library). You will need to run an *outer* optimisation to find the value of the...

Hi Does anyone know of any automatic way of mapping out the dependencies of a function -- i.e. automatically listing which other functions that function calls? I tried using all.names or all.vars, but I can't get it...

Thanks to everyone that responded on this subject -- 4 responses with 4 separate solutions to the problem! Thanks especially to Gabor Grothendieck for introducing me to "blat", the freeware emailer executable which was the solution I implemented in the end...

Philippe You seem to have the right answer already, unless I misunderstand... If I define: > x = "Hello \"World\"" Then the default print method for this character string will give the rather ugly looking: > x [1] "Hello \"World\"" But this is...

With regards to my question below, I've found a way to do it: all.names(body(test)) Seems to do the trick. Still, if there are any tools already developed for mapping the dependencies between a set of functions...

Hi. I have the following question about reading from large data objects from within R functions; I have tried to simplify my problem as much as possible in what follows. Imagine I have various large data objects sitting in my...

Thanks to everyone who replied on this subject. Clearly, two rows of the correlation matrix which have similar numerical entries represent two variables which have similar correlations with the other variables. Therefore clustering using a distance metric (e.g. dist...
