Hello to everyone,... I am a new R ambitious user. I would like to be the first at my department using R, but I have encountered a difficulty during the last days that I cannot overcome reading help() and searching over the net. Problem: I have multiple files with financial data like the following (header included): E.g.: filename: AOL.txt aol.txt 4 3 5 3... filename: IBM.txt ibm.txt 6 2 5 2...

Hello, Happy New Year!... I am encountering a problem trying to work on the data that I load in R. I have loaded to R a series of stock data using (csv files are named e.g. IBM.R) length.R <- length(list.files(".", pattern=".R")) # the number of files with one #column in the directory "./" ending to ".R" for (i in 1:length.R) {

Hi to all, In other statistical software, such as Eviews, it is possible to regress a model with the Least Squares method, assuming that the residuals follow an AR(q) process. For example the resulting regression is something like y = 1.2154 + 0.2215 x + 0.251 AR(1) How is it possible to do the same in R? Thank you very much in advance, Constantine Tsardounis http://www.costis.name

Dear Sir, First of all Happy Holidays!,... I am writing to you because I am a bit confused about ARCH estimation. Is there a way to find what garch() exactly does, without the need of reading the source code (because I cannot understand it)? In Eviews (the results at the end) I am getting different results than in R (for those that have the program I do: Quick -> Estimage Equation ->

Dear all, is there any function to calculate the center of a polygon mass in R? Actually I need to find the best location within polygons to place labels. Thanks for any hint Jens Oehlschl?gel -- COMPUTERBILD 15/03: Premium-e-mail-Dienste im Test\ --------...{{dropped}}

Hi all, I am using c++ functions in R by Rcpp and inline packages. The code is quite simple, but the R session always automatically crash after some running time. Does anyone here familiar with Rcpp and inline? What¡¯s the problem in the following code? I have checked the input values, no NA and other strange value exists. Thank you for your attention! > mkc <- cxxfunction(

Dear all, Thank you for any help. I have a data.frame and would like to plot it in 3D. I have tried wireframe() and cloud(), I got scatterplot3d(xs) Error: could not find function "scatterplot3d" > wireframe(xs) Error in wireframe(xs) : no applicable method for "wireframe" > persp(x=x, y=y, z=xs) Error in persp.default(x = x, y = y, z = xs) : (list)

The division part of the following code is not executing - (seq(n-1)*mean(XS)-cumsum(XS[seq(n-1)]))*diff(XS)/((n-1)*var(XS)) Note: Prof Yatracos: Would you please send them one example ?

Tristan, could you please run your xattr test against it? xs->base used to be allocated a 4K size and all the contents in the bucket are copied to the it. So in ocfs2_xattr_bucket_set_value_outside, we are safe to use xs->base + offset. Now we use ocfs2_xattr_bucket to abstract xattr bucket and xs->base is initialized to the start of the bu_bhs[0]. So xs->base + offset will overflow

Hi Rich, While I was looking at hivex today I ran coverity on it. It spotted one problem but missed a similar one nearby. The following are from Hivex.xs: (generated by generator.ml) void node_set_values (h, node, values) hive_h *h; int node; pl_set_values values = unpack_pl_set_values (ST(2)); PREINIT: int r; PPCODE: r = hivex_node_set_values (h, node,

Thank you Thierry. I'm trying to following your suggestion in the example below, but getting: Error in get("xs", envir = my.env) : object 'my.env' not found. library(shiny) library(shinydashboard) myApp <- function(x, ...) { xs <- scale(x) my.env <- new.env() assign("xs", xs, envir = my.env) shiny::runApp(app) } app = shinyApp( ui =

Hello, Here is a dilemma I am having for a long time. But, I couldn't figure it out. I have an vector of Y and a data frame named "data",which contains all Xs. I tried to be more efficient in fitting a simple linear regression with each X. Firstly, for (i in 1:(dim(data)[2])){ model<-lm(Y~data[,i]) # this is not what I want since the name of coefficient will be data[,i] # I

hivex-1.3.10 does not pass the sles11sp3 post-build-checks anymore, 1.3.8 was still ok. The relevant output is: ...

There is some redundancy at the instruction format level in the x86 .td files. For example, in X86InstrFormats.td: // SSE1 Instruction Templates: // // SSI - SSE1 instructions with XS prefix. class SSI<bits<8> o, Format F, dag outs, dag ins, string asm, list<dag> pattern> : I<o, F, outs, ins, asm, pattern>, XS, Requires<[HasSSE1]>; // SSE3 Instruction

Hola compañeros de la lista. Estoy aprendiendo a usar el paquete "rsm" para superficies de respuesta.

Dear R-List users, Can anyone explain exactly the difference between Weights options in lm glm and gls? I try the following codes, but the results are different. > lm1 Call: lm(formula = y ~ x) Coefficients: (Intercept) x 0.1183 7.3075 > lm2 Call: lm(formula = y ~ x, weights = W) Coefficients: (Intercept) x 0.04193 7.30660 > lm3 Call:
