similar to: AKIMA color contouring

Dear all. I am using the akima function to produce 3d contour plots using interp based on irregular data. using the eg in the akima manual library("akima") data(akima) plot(y ~ x, data = akima, main = "akima example data") with(akima, text(x, y, formatC(z,dig=2), adj = -0.1)) ## linear interpolation akima.li <- interp(akima$x, akima$y, akima$z) image (akima.li, add=TRUE)

Dear all I have this table > dput(mat) mat <- structure(c(2, 16, 9, 2, 16, 1, 1, 4, 7, 7, 44.52, 42.8, 43.54, 40.26, 40.09), dim = c(5L, 3L)) And I want to calculate result for contour or image plots as I did few years ago. However interp does not compute the z values and gives me zeros in z matrix. library(akima) > interp(mat[,1], mat[,2], mat[, 3], nx=5, ny=5) $x [1] 2.0 5.5

I am trying to load the GRASS library and am getting the following error: > library(GRASS) Loading required package: akima Error: package 'akima' could not be loaded In addition: Warning message: There is no package called 'akima' in: library(pkg, character.only = TRUE, logical = TRUE, lib.loc = lib.loc) This is on R 2.0.0, library(GRASS) is installed, and update.packages()

I am using the Akima interpolation package to generate an interpolated color contour plot. It is working very well, except for one problem. The data that I have represents real-time readings from a thermistor string vs. time, so the data points are often very nearly in a rectangular array, since the thermistors are read at regular time intervals and they are equally spaced physically.

The akima package has a problematic license (it doesn't allow commercial use), so it's been recommended that people use the interp package instead. When I use interp::interp instead of akima::interp, I get reasonable output from your example. So that's another reason to drop akima...

Dear R users, I am having problems loading the akima package. I use Windows XP, and R version 2.12.1. When I try to load the package I get this error message: Error: package ''akima'' is not installed for ''arch=i386'' Any help appreciated and thanks you for your time.

Dear all! I'm using R 2.12.1 in Ubuntu 10.04. Problem is that when using functions like interp (package akima) and akimaInterp (package fUtilities), I get different results every time for the same data set. I've checked the interpolated results, and two examples (in attachment) have different sum of NA values. Also when I subtract the x,y,z values from two interpolations of the same data

Short story: cannot get Kerberized NFSv4 to work. I've googled a great deal and cannot find where I have goofed (and there sure is a lot of misleading and just plain incorrect information out there), so would appreciate another pair of eyes. NFSv4 without Kerberos does work fine, as does ID mapping. We're using NFSv4 in production with sec=sys, but I'm not happy with that. My

Dear all; First of all, this is probably a more conceptual question than a R-related one, but still want to give it a try. When working with the interpolation function "interp" from the package akima and the triangulation function "tri.mesh" from package tripack I've got NA's for the interpolation and "error" for the triangulation. The data is arranged in a

Hi, I'm currently hunting a bug in the akima library, especially in the code behind the interpp.old function (bi-variate linear interpolation). It is based on a triangulation algorithm, interpolation at a given point needs to know the triangle which contains this point, then the interpolation is a straightforward calculation based on the three vertexes. The problem is: Sometimes the triangle

Dear R users, I want to do a fitted.contour plot of selected columns of a dataframe M with M$AM and M$Irradiance as x and y axes respectively. The level of the contour shall be determined by M$PR. Some words on my data first. Dataframe M looks like: head(M$Irradiance) [1] 293 350 412 419 477 509 head(M$AM) [1] 2.407 2.161 1.964 1.805 1.673 1.563 head(M$PR) [1] 70.102 72.600 75.097 80.167

Hi everyone I was using spline to interpolate single or two consecutive missing data points in time series. However, when it comes to longer gaps in the data the spline function generate new data for both my known and unknown data (see below). Aside from not understanding why this happens, I thought thought I might try function "aspline" in library (akima). However, I cannot install or

Hi, I am hired to translate into FORTRAN R functions. It works great and my customer is happy. I am going to translate a function that call aspline in the library AKIMA. This function call 2 FORTRAN routines that must be include (I guess) in the package AKIMA. And I have some questions. Is the fortran code really included in the R package AKIMA ? In other word, do I have a mean to call these 2

Dear S-users. This should be an easy one: How do I change pages on an X11 graphics device under linux? I thought that the page-up/page-down keys were supposed to do the trick, but the frame (window) seems to be kind of immune to any kind of keyboard input. The only reaction I ever see is that the mouse pointer changes to a "+" when moved into the frame. I issue these commands:
