Re: [R] imaging and contouring

The help for filled.contour suggests using the plot.axes argument to annotate a plot, try changing the last part of your 3rd example to: filled.contour(nlong,nlat,z1,col=rainbow (100),xlab=longitude,ylab=latitude, plot.axes=map(add=TRUE)) Or filled.contour(nlong,nlat,z1,col=rainbow

Re: [R] Help on hypothesis testing

There is a z.test function in the TeachingDemos Package. Note however that this function is meant for teaching purposes as a stepping stone for students to learn the syntax and output for hypothesis test functions before learning about t tests etc. The z.test function only does one sample tests.

Re: [R] Ternary or Triangular Plots (soil texture triangle plot)?

There is also the triplot function in the TeachingDemos package that does some of what you want (but always shows the full range 0 to 1 on all axes). I expect that each of the implementations out there does part of what you want and you may need to find which will come closest, or find which is

Re: [R] Maps of Canada and some (very) simple instructions

I found a shapefile for a map of Canada at: http://www.vdstech.com/map_data.htm you can read this in and plot it using the maptools package (or the sp package and friends if you want more control): library(maptools) tmp - read.shape('c:/maps/canada') tmp2 - Map2poly(tmp) plot(tmp2) For

[R] [R-pkgs] New Package blockrand

The package blockrand is now available on CRAN. This package aids in doing block randomizations for clinical trials or other situations where subjects or experimental units arrive over time and need to be randomized one at a time. The block randomization keeps the number of subjects in each arm

Re: [R] graphing and scrolling

in regards to the dynamic resizing, one would think that commands like plot.default {package:graphics} does it, as I am exploring other commands from graphics it seams like tkrplot may not be needed, I am not sure as I just started with graphics in R, maybe a

Re: [R] graphing and scrolling

thanks that was very helpful. i have been reading and trying to modify the code around to suit, but haven't been able to: first, maximize the chart with the window being maximized, the way it is it stays the same size after maximizing the window. The function tkrplot has optional

Re: [R] bug in map('world') ?

There is a function recenter.Map in the TeachingDemos package that can be used with the maptools packages (rather than the maps package) to move polygons around for better looking maps. The original idea was to put the Alaskan islands on the left of the map rather than having some of them on the

Re: [R] graphing dilemna

When barplots start getting complicated (and sometimes before that) you may want to start considering dotplots (package lattice) instead. For your specific problem you could possibly do the side-by-side plot, then using the output from barplot and the rect function you could plot a rectangle over

Re: [R] Need a hint

Here are a couple of quick thoughts on your problem. 1. Use alpha channels (may require you to produce all your graphs as pdf files). Fill each of your criteria categories with a mostly transparent color, e.g. the full contour of z[1] between 20 and 30 is 20% opaque and the full contour(s) of

Re: [R] Transferring R results to word prosessors

Just to add a couple of thoughts to the previous suggestions. If you really want output from things like summary.lm to have tabs instead of spaces then you can type: getAnywhere(print.summary.lm) at the R prompt and it will show you the (not quite) source of code that R uses to do the

Re: [R] putting text in the corner

par('usr') will give you the coordinates of the corners of the current plot. If you want to go a little beyond this (more like your legend example) by specifying that you want your text to be some distance from the bottom and left of the plot and have the distance not affected by the scale

Re: [R] Newbie question--locally weighted regression

Using a gam model (package gam, possibly others) will take care of the link function (and variance function) for you and allow using loess to fit the data. Here is a quick example to get you started, though you should read up on gam models yourself as well. library(gam) x - seq(0,1, length=250)
