Hi, I have an ESRI-Ascii-Grid file which looks like this: ncols 1001 nrows 1001 xllcorner 3539000 yllcorner 5379000 cellsize 1 NODATA_value -9999 766,65 766,65 766,67 766,69 766,7 766,72 766,74 766...
Hi, I have a SpatialPolygonsDataFrame (SPolyDF) and a SpatialPointsDataFrame(SPoiDF). The SPolyDF is a (very) large set of polygons (some 30.000) and the SPoiDF is actually a grid of some 60.000 points. I would like to use overlay...
Hi again, OK, it is not a problem of readAsciiGrid (maptools)! However: x <- 3539000.5 : 3540000.5 ## OK, readAsciiGrid adds .5 to the coordinates length(x) x[1:10] min(x) ## OK, this is the rounded value summary(x) ## I...
Hello, I try to plot some results of an analysis to multiple individual postscript files, like: postscript("A1_zonflow.ps",onefile=F) plot(s, type = "vectors", idx = 1:12,main="") dev.off() # postscript("vectors_paired_zonflow.ps",onefile=F) plot...
Dear R-users, is there any object-type or routine/function in R which can handle unequally spaced time-series data? I know that there is the library OSWALD for S-Plus, which is able to do so, but I...
G'day I try do compute some F-statistics of a singular spectrum analysis of a timeseries sv I run: > require(Rssa) > s <- ssa(sv) > summary(sv) Min. 1st Qu. Median Mean 3rd Qu. Max. -4.238 2.761 6...
Dear useRs, a first version of tm has just been released on CRAN. tm provides a sophisticated framework for text mining applications within R. It offers functionality for managing text documents, abstracts the process of document manipulation and eases the...

Hi, I imported a ESRIAsciiGrid with readGDAL(). The result is a SpatialGridDataFrame (SGDF). The projection of the grid (only the xllcorner, yllcorner ?) is: Projection LAMBERT Units METERS Spheroid BESSEL (more details at the end of this email) How can I...
Hi, I have a problem with library (rpart) (and/or library(tree)). I use a data.frame with variables "pnV22" (observation: 1, 0 or yes, no) "JTemp" (mean temperature) "SNied" (summer rain) I used function "rpart" to build a model...
Good morning, I'm trying to rebuild the basic strategy out of Andreas Clenow's book "Following the trend in quantstrat but struggling with the trailing stop. The rules are as follows (only for long trades): 1. *Entry rule*: Buy...

most probably this is a question with a simple answer but I have not found an answer to it anywhere yet: I took one of James Wettenhalls sample scripts (http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/) for radio buttons as...

Dear Brian, sorry, library(lattice) is loaded, when I start R, so I forgot to add this. I get "Ingo's title" if I plot directly to the screen. However, I do not get it if I use png() or...
