similar to: R - how to measure the distance?

I'm having trouble understanding the output from as.windrose(). For one thing, data on a boundary between sectors seem to be left out of the counts. I assume that explains the missing point in the output below (angle 45). Shouldn't one side of each sector interval be open, to include values such as my 45 in the example? Also, why does the angle 180 in my input apparently not result in

Hi... I got this new server at work that I have to get 100% up and running by tomorrow. It's running Samba 2.2.1a on SuSE 7.3 Pro It's supposed to be VPN - File and Printer Server The printers are: One OCE 700C / CS90 color copier and One OCE 3165 And there is only one problem left. I can install the printer drivers for Win9x & NT on the samba server. But I can't figure out how to

Hi, I have just upgraded my computer to Intel Core i5-4430 Quad Core @ 3.0 GHz (supports VT-d), ASRock B85M Pro4 micro-ATX LGA1150 motherboard (supports VT-d), 8 GB Kingston DDR3-1600 memory and Cooler Master Elite 311 ATX casing (all for SGD$501). I made my computer upgrade on Independence Day 4th July 2013. I have also flashed the UEFI BIOS of ASRock B85M Pro4 motherboard to version 1.50.

Hi everyone, I want to create my own distance measure, other than 'euclidean' or 'manhatan', to use in cluster pckgs. To do this I think that I need to change dist(), in mva pckg, or daisy(), in cluster pckg. (or is there a cleaver way ?) But this functions are in fact things like: .Fortran( "daisy", ... ) or .C("dist",...). I tried unsuccessfully to find

Dear all: I want to ask question about "binary" distance measure. As far as I know, there are many binary distance measures,eg, binary Jarcad distance, binary euclidean distance, and binary Bray-Curtis distance,etc. It is even more confusing because many have more than one name. So , I wan to know what the definite name of the binary distance measure of the "dist" function

Dear R, I have a bunch of geographic locations specified by lat-long coordinates. What's an easy way to calculate geographic distance between any two points? OR, perhaps there is a function for calculating a distance matrix for K sites? Sincerely, Scott Chamberlain [[alternative HTML version deleted]]

Hi folks, Here is the problem. I am giving an example .I want to find a measure of similarity or dissimilarity among ranking (of students of a same class of size say 50)by two judges. But instead of observing the rank of all the 50 students (Where we could have used rank correlation measures)in each case what I have is 2 list of top 20 students chosen by each judge. The following paper gives out

Hello, I have current data from a nortek ADP, which is basically current speed and direction data in a 3 dimensional X Y Z format http://www.nortekusa.com/usa/products/current-profilers/aquadopp-profiler-1 The instrument logs data in a complex way and I was wondering if anyone has had any experience using R to at least read the data, and perhaps smooth it as well. If so, are there any

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm generating a symmetric correlation matrix using a data matrix as input: mat <- cor(data.mat) My question is: Is there a more memory efficient way to store this data? For instance, since: all(mat == t(mat)) every value is duplicated, and I should be able to almost half the memory usage for large matrices. Any thoughts/comments? Cheers,

Hi, I am new to clustering and was wondering why pvclust using "maximum" as distance measure nearly always results in p-values above 95%. I wrote an example programme which demonstrates this effect. I uploaded a PDF showing the results Here is the code which produces the PDF file: ------------------------------------------------------------------------------------- s <-

Dear R users, I know that this could easily be solved within a GIS-package, but sometimes it's more convenient to use R. So here's my question anyway... Does anyone of you know about any R-functions/code that calculates the distance between a number points and a polygon or polyline? I have looked thru the different libraries that deals with spatial statistics but haven't found

Hello Friends!!! I would want draw a circular histogram, and I would like draw a polygon with a circular side. This is easy if I use the functions polygon and arc, but I want that the polygon with a circular side have background colour. The polygon created with function polygon can have background colour, but the surface created with function arc can?t have background colour. How I could create a

Hi, Suppose I have n variables, X1, X2, ..., Xn and want to visualize the pairwise correlations on a 2-dimmensional plot. In particular, I plan to mark down n dots on a piece of paper and dot i represents Xi, in a way such that the highly correlated variables are placed closer; that is, shorter the distance between two dots the higher the correlation are between two corresponding variables. Do

Dear R-user, Is there a way in R to locate the nearest 5 indices to a station, based on distances in a distance matrix. In other words i want to have nearest stations based on the distances in the matrix. The distance matrix, i have, has dimension 44*44.
