similar to: bandwidths for bivariate density estimation

Hi to all, I'm sorry for posting this question, I am sure I am missing something important but after reading the documentation I cannot find where the problem is. I want to add a legend to a figure. If I use a simple example drawn from the R Reference Manual such as, for instance: x <- seq(-pi, pi, len = 65) plot(x, sin(x), type="l", col = 2) legend(x = -3, y = .9,

Thank you for your reply. I know the x in dpik() means the vector. But I don't know how to import into c() with a huge metadata (>1000). Following is my some try, and the h is: [1] 0.001180569, which seems to be feasible.

Hi, I have two separate questions relating to the KernSmooth package. I am using the dpik function from the KernSmooth package and receive the error Warning message: In kappam * Gcounts : longer object length is not a multiple of shorter object length I saw an earlier post , but the issue was using the bkde fxn and the person appeared to be using too small of a bandwidth.

Hi all, I've recently upgraded to R version 2.1.1 and when trying to inspect the contents of many packages in the library (for instance library\MASS\R) I've realized wordpad, or the notepad, won't open them since they have *.RDB and *.RDX extensions which these editors cannot recognize. However, libraries in previous versions of R did not have these extensions and I could inspect

Dear list, I'm using the quantreg package for quantile regression. Although it's fine, there're is some weird behavior a little bit difficult to understant. In some occasions, the regression results table shows coefficients, t-statistics, standard errors and p-values. However, in other occasions it shows only coefficients and confidence intervals. Therefore, the question is... Is

Hi there and thanks in advance. Nowadays I am working on the plug-in bandwidth selection with R. Firstly, my 1010 data is the return rate from Yahoo Finance. Secondly, my code is following: > r=read.table("/Users/user/Desktop/research/a.txt",sep=",",header=TRUE) > x<-r[8:1010,] > library(KernSmooth) >

Hi I hope this is going to the right place. I am trying to write a program which uses KernSmooth library to estimate mutual information between two time series at various different lags. At the moment it’s producing negative values, which is supposed to be impossible (something is fishy). I am summing across one row of the matrix to get p(value is in bin x) and summing across the columns to get

I am attempting to install a anchoring vingettes package for R and I seem to have a problem with unzipping the files in R. I use the command that can be found here <http://wand.stanford.edu/anchors/>. Here is the dialog I get after entering the command: > install.packages("anchors", dependencies = TRUE, +

Hi, I'm relatively new to R and R development, so please forgive me for any obvious errors. What I am trying to do is use the command dpik within the package KernSmooth to estimate bandwidth parameters for GPS telemetry data. I have been able to get this to work on a case by case basis without any problem, but would like to extend this so that I can batch process many different animals for

Hi all, I'm not sure who to ask this, so I'm posting this here. I just ran: require(KernSmooth) And got (I bolded the text): Loading required package: KernSmooth KernSmooth 2.23 loaded *Copyright M.

Folks: When using rsync to copy huge amounts of data I've found that a significant amount of time is spent computing the checksums. Sometimes hours, ... sometimes days - it depends on the total amount of data checked! And after that sometimes it's only a few files that need to be updated. I've pulled the latest git (rsync-3.1.1pre1) and didn't see anything to address this (or I

Hi there, I am reading the 2004 paper "Smoothing with mixed model software" in Journal of Statistical Software, by Ngo and Wand. I tried to run their first example in Section 2.1 using R but I had some problems. Here is the code: library(nlme) fossil <- read.table("fossil.dat",header=T) x <- fossil$age y <- 100000*fossil$strontium.ratio knots <-

Hi, First, let me thank Jaroslaw for making this survey. I find it quite illuminating. Now the questions: * the #1 solution below (based on cumsum) is numerically unstable. Specifically if you do the runmean on a positive vector you can easily get negative numbers due to rounding errors. Does anyone see a modification which is free of this deficiency? * is it possible to optimize the

Hi, I try to set up dovecot as a proxy server, to proxy requests to several dovecot-based backend servers. I wand external clients who connects to this proxy Dovecot to use TLS (this is easy to set up) while want to have unsecured (plain IMAP/POP) connections to backends. You see, links to backends are over LAN so no TLS needed, and these backends are poor old machines (with old Docecots like

I have tried installing the package (ROCR) with this command: Install.packages(ROCR) And with this command on the command line R CMD INSTALL ROCR_1.0-4.tar.gz But both times I get exactly the same error shown below, I don't understand what is wrong, is this an error in the package code? Thank you Philip probinson@bioinform08:/tmp/RtmpO0rFbx/downloaded_packages$ R CMD

Hi Spencer, I have seen your name on the web site, and perhaps you can help me with my R problem. I'm trying to use KernSur to put in evidence a substructure in a bidimensional plot. My problem is that, in order to get the density in the low density areas (in which the substructure is located) I should use different bandwidths. How I can do that? Also, I think that the best choice for my
