Hello, I would like to use the cbind() function to construct a matrix used in the middle of a function as following for (i in 1:1000) { b[i] <- function(cbind(a[[1]][[i]], a[[2]][[i]],a[[3]][[i]],...a[[67]][[i]])) } Is there an easy way of achieving this rather than "cbind" every column? -- View this message in context: http://www.nabble.com/cbind%28%29-tf4724534.html#a13507633

Hallo, does a package for Matlab exist in R? If yes, where can I find it and how can I install it under R? Thanks, Corinna

Dear R help list members, I am experiencing difficulty in trying to generate a subscript '2' in an axis label. Although I can get the '2' into a subscript using expression(), R then forces me to leave at least one space between the '2' and the following character. My label is supposed to read 'N2O concentration (ppm)', and the space between the '2' and

Hello everyone, I would like to use the "cbind" function to construct a dataset, combining some variable I defined before. The codes are something like var1 <- ... var2 <- ... var2 <- ... ... data <- cbind(var1,var2,var3...) The problem is I would like some flexibity in the data, i.e. the number of the variables are not fixed. Is there a method of combine the uncertain

Dear list, Is there an exact formula / safe rule of thumb that allows one to express the value of --max-ppsize as a function of the value of getOption("expressions") ? ?options tells "If you increase it [the expressions option], you may also want to start R with a larger protection stack". Motivation is to determine stack size of a Java vm used to launch R with a given

Hi friends, does anyone know how we can 'control' R from Visual Studio .NET? e.g. start R, send a set of commands, save the results and open the results using Visual Studio.

I have a data frame with three columns, one coded as a factor. I would like to separate my data out into separate data frames according to the factor level. Below is a simple example to illustrate. I can get R to return the data in the correct format but cannot work out how to get separate data frames. I am a newcommer to programming in R so am not sure what I am missing! Thanks, Emily

Dear Guru's, Is there a package (R of course) with programs for diagnostics - roc, sens , spec, kappa etc? Best wishes Fredrik L

Can someone direct me to an R function that properly computes standard errors of data obtained from a complex survery design, i.e. perform alnalyses similiar to those that can be performed with SUDAAN, particularly for a non-parametric one-way ANOVA, e.g. signed rank test?

Good afternoon! I'm trying to use the survey package to get a better point of view for my data, but i need some piece of advice: i have some data from a survey which has been stratified using 2 criteria: region(7 values), size of locality(5 values) Using the survey pakage how can i define in a correct way this design (taking into account all 4 strata not just one as in the Survey

Dear HelpeRs, I'm very fond of Sweave and I use it as often as possible. It'a a pity I can't use it for larger projects or can I? For instance suppose I have three files file1.rnw, file2.rnw and file3.rnw with Sweave code. Working on file2.rnw I whould like to exclude file1.rnw and file3.rnw temporarily and joining all of them later. This amounts to a mechanism similar to using

Hi All, I am trying to make a loop for a function and I am using the following codes. "p" and "var" are some matrix obtained before. I would like to apply the function "gpdlow" for i in 1:12 and get the "returnlow" for i in 1:12. But when I ask for "returnlow" there are warnings and it turns out some strange result. for (i in 1:12){ gpdlow

Hello, I am using the following codes to plot a histogram and density line for x. For the density line, I just want it to show the two tails, eg, for x larger than 0.05 ans smaller than -0.05 hist (x, seq(-0.1,0.1,0.01),freq = FALSE) lines (density(x,bw="SJ"), x> 0.05 & x< (-0.05), col = "red") But is does not work, can anyone give me some advice? -- View this

Hi, I would like to apply the following function for i between 1 and 12, and then construct a list of the return series. for (i in 1:12){ ewma[i] <- emaTA(calm[[i]]^2,0.03) standard[i]<- calm[[i]]/sqrt(ewma[i]) standard <- cbind(standard[i]) } But it does not work. Could anyone give me some advice how can I achieve this? Many thanks -- View this message in context:
