Using R 2.5.1 on Windows XP Professional, and PBSmapping package version 2.51, I have encountered some behavior which puzzles me. I am including the package's listed maintainer on this email but also seek the thoughts of the R-help community. I have a set of EventData, which I want to plot as points, and to color the points according to some criterion. It turns out that some of my

Hi, I've used the Mathematica to produce 3D graphics, contour plots of a bivariate normal distribution Now I want make these graphics in R, but i do not know how. I would like to: - Plot a 3D graph for some different variance matrix - Plot the contour plots - Find and try to plot (in the 3d graph ou contour plot) the (1-a)% confidence region based in a chi-square(a) with the degrees of

Hi, I am new to this mailing list. Didn`t find the answer in the archives. But I guess, there are people out there, who know the solution: In an automatic script, I want to produce simple plots. First I prefer pdf, because of scalability and standardization. But when I have too many datapoints (say 300.000) the viewing and printing is very, very slow. So I decided to take some bitmapped format

I cannot seem to get this to work? I have weighted data points that I want to fit an sd-ellipse to, but the ellipse is not right? I have attached a .tiff of what I get. I'm wondering if it's not looking at my actual data, but taking the data from the example? I ask this because I don't know where "Title" comes from in the graph? Also, I want to put calcentre=FALSE, but if I

You'll find that it is a lot easier to do it in R: # lets first simulate a bivariate normal sample library(MASS) bivn <- mvrnorm(1000, mu = c(0, 0), Sigma = matrix(c(1, .5, .5, 1), 2)) # now we do a kernel density estimate bivn.kde <- kde2d(bivn[,1], bivn[,2], n = 50) # now plot your results contour(bivn.kde) image(bivn.kde) persp(bivn.kde, phi = 45, theta = 30) # fancy contour with

I thought about that star graph again, and realized that it would be quite a handy thing for visualizing cyclic data like time or compass direction. Here is a cleaned up (and renamed) version to do a polar plot that starts at the right and goes counterclockwise or a 24 hour clock plot that starts at the top and goes clockwise. There are probably other varieties that would be interesting. Jim

I thought I had this fixed, but apparently not. It works okay from the console, but not from the view. I have the following: # partial schema create_table "users", :force => true do |t| t.string "login", :null => false t.string "first_name" t.string "last_name" t.string "email", :null => false

I''m having the devil''s time trying to get things laid out correctly. I''ve attached a screenshot so that you can get an idea of what I''m seeing. I''ve got a very unattractive space under the two combo boxes, and another one under the buttons. I don''t understand how to reduce this. I know it''s impossible to guess what idiocy I might have

(Sorry about the delay -- currently attending ICASSP) Hi, Haven't looked at all the details, but what's clearly wrong is that you need to put the *compressed* packets in the jitter buffer and decode them only when you _get() them.

Hi everyone, I''m building partial and I need to use a variable inside of another variable name: I''ve tried like this: <div class="form_row"> <label for="<%= field %>"><%= field_title || field.humanize %>:</ label> <%= form.text_field field, :size => User::field.upcase_SIZE,

Dear R friends. After having some troubles learning how to create a ffdf object, now I find myself having problems saving it. this is the data i´d like to save: str(DATA) List of 3 $ virtual: 'data.frame': 6 obs. of 7 variables: .. $ VirtualVmode : chr "double" "short" "integer" "integer" ... .. $ AsIs : logi FALSE FALSE FALSE

Hi guys, I''ve got a problem here which i need help from the pro''s in this mailing list I have a legacy app where the User table has a custom structure where "User_id" (username) is the primary key as well as the username used to log in User.rb (model) class User < ActiveRecord::Base set_table_name "cmf901" set_primary_key "user_id" end

Dear all, I would like to draw a dendrogram and mark some parts/branches (by using "segments") including their labels. If I draw it without specifying the length of x axix, I am able to do that (as in My dendrogram 1 of the following codes). However, if I want to specify the x axix, I am not able to draw marking line (by using "segments") including labels (as in My dendrogram

Dieter Menne pointed out that the (small) xml attachment didn't make it. Here is an in-line version (see end of message). Let's hope it works this time. I'm struggling with interpreting XML files created by ADODB as data.frames and I'm looking for advice. Note: This xlm contains a result set which comes from a rectangular data array. I've been trying to play with

I built a small form in wxFormBuilder.

Using the PPC frsqrte and fres instructions, I got the percentage time take in the smoothing code in _vp_compute_mask() down from 13.64% to 1.88% of the running time. In my local copy of Vorbis I have a fast_math.[hc] in vorbis/lib and have a _fast_sqrt() inline in fast_math.h. If anyone else wants to try it out, it follows. I can currently encode my test file (the first 15 seconds of
