Hello R Users, How to make a variable equidistance with time i.e. how to interpolate a variable if it is not sampled at equal time interval. Many thanks, Regards, Yogesh [[alternative HTML version deleted]]

Dear all, I'm trying to interpolate a dataset to give it twice as many values (I'm giving the dataset a finer resolution by interpolating from 1 degree to 0.5 degrees) to match that of a corresponding dataset. I have the data in both a data frame format (longitude column header values along the top with latitude row header values down the side) or column format (in the format latitude,

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

Hello, I'm dealing with the following problem: I have a table with x and y coordinates and corresponding values of a mineral concentration, let's call it z. Can someone provide me a short step-by-step manual for the steps necessary to get a contour map? How to sort and interpolate my matrix to an equidistant grid which can afterwards be plotted by contour(x,y,z)? (e.g. fill the

Hi all, If I use a moving average, it will smooth the choppy time series, but it will lead to lagging... How do I smooth timeseries without the lagging effect? Thanks!

Hello, My colleague and I would like to write Java code that invokes R to do a simple TTest. I've included my sample java code below. I tried various alternatives and am unable to pass a vector to the TTest method. In my investigation, I tried to call other R methods that take vectors and also ran into various degrees of failure. Any insight you can provide or other Web references you

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 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.

From: Thorvald Natvig <slicer at users.sourceforge.net> Some optimizing compilers miscompile the current SSE optimizations when full optimizations are enabled. By using output value pointer instead of a return value, we can bypass this misbehaviour. --- libspeex/resample.c | 8 ++++---- libspeex/resample_sse.h | 24 ++++++++---------------- 2 files changed, 12 insertions(+), 20

Hi How can I do the same has interp in s+ with R ? I've looked to "approxfun" but didn't figured out how to do it.

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

Dear R-devel, Apologies for bothering y'all with this seemingly perennial question. A user reported problem with my most recent version of randomForest (4.4-1), and I was able to reproduce it with his data with R-2.0.0 patched (2004-10-24) on WinXP Pro. The problem is that it crashes R on Windows. However, it does not happen on Linux (tried SUSE ES8 on our Opterons and Quantian on my

Dear List, I'm using interp() to prepare 3d data for plotting with the contour() function. If have x,y and z data. All are arrays. X and Y are sampled in an orderly fashion on a grid (a circular sub-area of a grid - see plot). I'm trying to use interp() to get x and y arrays and a z matrix that can be fed to contour(). This is the command:

Dear R developers, I plan to upload a first version of my R package RnavGraph to the R CRAN server in a week or two. However I'm still struggling with an image resizing function written in C as a tcl extension. I did all my development in Ubuntu, and everything works fine in Ubuntu, however my attempts to compile this C function under Windows or OSX have all failed. I provide a minimal self

Hi, This is a question on how to resolve weak symbols from the binary for symbols that are also llvm::Module-local. Currently, the JIT seems to favor resolving to module-local symbols over existing symbols: $ cat symbols.cxx extern "C" int printf(const char*,...); template <class T> struct StaticStuff { static T s_data; }; template <class T> T

Hello, I'd like to make a z(x,y) plot for irregularly spaced x,y. What are routines are available in R for this purpose? Thanks, Mark

Hello R cracks The image() function requires strictly increasing x and y values and z as a matrix. Actually, I don't have equally spaced variables, but anyway want to plot an colored image() (with z-information). An example of my problem is here: a<-data.frame(rnorm(100), rnorm(100), runif(100)*100) How can I plot this data as an image (x=a[,1], y=a[,2] and z=a[,3])-> according to
