Hi, In the order() help file, there is an example like: a <- c(4, 3, 2, NA, 1) b <- c(4, NA, 2, 7, 1) z <- cbind(a, b) (o <- order(a, b)); z[o, ] How can I do something like "order a in ascending order, b in descending order"? And say I have a third vector c, and I'd like to add this to the previous condition "a ascending, b descending, c

Hi all, I would like to plot some points and define the bg color of my graphics. But the bg parameter set is defined for the. whole graphic. In fact, i would like to use something like : box(bg=gray(0.9)). So, the background concerns only the plot region and not the main title, the x title and the y title. The option col for the function box() concerns the contour and there is no option

Dear R users: I am a relatively experienced Splus user but new to R, using the version for Windows 2000. Splus allows the user to generate multiple graph pages in the graph window. For example, if you have two plot(...) commands in the script than two pages in the graph window will be created. However, when I tried this in R, the second plot will just overwrite the first plot in the graph

Dear all, I have to minimize a (real) function in a loop (say i in (1:1000)) and store its ``$estimate'', via l2estim<-nlm(f.minimo,c(-.01,0.1))$estimate into a vector for further analisys. Since the function's behaviour is quite peculiar (in the sense that in the simulation study it may not have a minumum), sometimes I get the the warning Error in nlm(minimo, c(-0.01, 0.1),

I'm doing m <- match(matriz, origen, 0) where matriz is a 270x900 matrix and origen a 11675 elements vector, and is taking a very long time. Is match a function implemented in C? If not, would a C code be faster?

Dear All, I'm happily extracting data of temperature from an oracle db under R via RODBC. After manipulating the extracted data I put them into a data.frame 'dati' which is as follows: > dati DATA tm.

Good morning, I installed on xen a windows XP and a Windows 2003 domU. Windows operating system does not know the real network card but it setup up an AMD pcnet card 10mbps. Is it possible to setup a full virtualized domU with a real network card ? I installed also windows on a trial xen enterprise and real network card seeems to work fine. What differences between xen and xen entrprise as far

Estimados su ayuda con la ejecución del comando lapply() Tengo creada la siguiente función invertir(matriz,n) que me permite cambiar la posición de los elementos de una matriz. invertir<-function(Matriz,n){ a<-Matriz b<-matrix(c(rep(0,n*n)),n,n) c<-matrix(c(rep(0,n*n)),n,n) for (i in 1:n) {b[i,]<-a[(n+1)-i,]} for (j in 1:n) {c[,j]<-b[,(n+1)-j]} return(c) }

Muchas gracias Xabier. He intentaddo trabajar con la sparse matrix pero al pasar tdm a matriz me dice también que "cannot allocate a vector of size 12 gb". He hecho tdm<-as.matrix(tdm) ¿Está bien hecho eso para trabajar con la sparse matrix? Gracias!

I am testing several Operating System Streaming products to streams virtual desktops. They always requires pxe boot but xen seems to have a pxe which is not suitable. I got the same problem with kqemu and kvm and I solved it using gpxe. With xen I tried to chainloading gpxe (following gpxe wiki) but hvmloader fails to load it (memory problem?). Any workaround

Buenas, El archivo de R ocupa 33 megas. La matriz que quiero construir cupa 14 gb. En el disco local (C) tengo 400 gb disponibles de 670. No estoy muy puesta en trabajar con este tipo de datos. ¿Qué diferencia es trabajar con data.frame? Gracias!
