While trying to find a bug in my encoder, i came across an error in the spec where it defines the structure of the ident header... the spec defines 100 extra bits which aren't actually in the headers... NSBS, NMBS and NBS don't appear in a 3 2 0 header... the actual structure is as follows //0 - 7 header ident (8 bits) //8 - 55 theora ident (48 bits) //56 - 63 ver major (8

I have a raster (which I called glc), which I read into R as a raster with "raster.create.from.file" from the raster package (R-forge). Values in glc range between 1 and 27 (whole numbers only). I'd like to extract all cells with a value of 1 to create a new raster with only the cells that have a value of 1, or to extract the xy values of all raster cells with a value of 1. Could you

ext2 & ext3 lists, Attatched is a patch that allows ext2 and ext3 to link correctly when the kernel is configured with a large NR_CPUS. We do have an immediate need for this patch. Any opinions on this? The per-cpu lists are causing the kmalloc to fail due to allocating more than the max. thanks mh -- Martin Hicks Wild Open Source Inc. mort@wildopensource.com

Hi, str() on raster objects fails for certain dimensions. For example: > str(as.raster(0, nrow=1, ncol=100)) 'raster' chr [1, 1:100] "#000000" "#000000" "#000000" "#000000" ... > str(as.raster(0, nrow=1, ncol=101)) Error in `[.raster`(object, seq_len(max.len)) : subscript out of bounds This seems to do with how str() and

Hi R-User I was trying to make a raster map with WGS84 projection in R, but I could not make it. I found one data set in Google that data is almost the same format as of mine. I wanted to make a raster map of temperature with 1 degree spatial resolution for the global scale. I could make it in the GIS software but I do have many variables (to be many raster images) and ultimately I am

Hi all, I am trying to plot a raster object (I can explain why but the point is that it would be a raster objeçt).. I have selected a small code to show you exactly the problem require(raster) test<-matrix(data=runif(10000),nrow=100) m<-raster(test) plot(m,axes="FALSE") axis(1,at=c(0,1),labels=c("a","b")) # THIS DOES NOT CHANGE THE INVISIBLE AXIS WHILE

Many thanks, That worked, since the NAMESPACE file incudes a warning about editing it directly I ysed the reoygen tag in the fucntion script #' @import raster.

Hi, I've been running the foreign language training program The Rosetta Stone(TRS) on wine for months now, but a recent commit to the linux kernel has caused TRS to be unable to read the DVD drive, where the program's data files are kept. Strangely, winefile can still read the data DVD, but TRS cannot, and I'm stumped. Below is the guilty kernel commit (rather long, sorry). Can

Dear community My aim is to import multiple .tif raster files using the help here: https://stackoverflow.com/questions/52746936/how-to-efficiently-import-multi ple-raster-tif-files-into-r Does anyone now about the error "subscripts out of bounds"? I am not sure about the check with alllrasters: is list() ok or should there be a number (the number of imported .tif files? Kind regards

Hello: I am using R raster package to replace ArcGIS when processing multiple shp files. However, when I export R raster back to ArcGIS, it couldn't recognize R raster file correctly. For example, I used {raster} package and got a RasterLayer as followed. class : RasterLayer dimensions : 8280, 18480, 153014400 (nrow, ncol, ncell) resolution : 0.008333334, 0.008333334 (x, y)

Hi, I am finding the recently added [1] functionality of embedding raster images into plots on R devices very useful! Thanks to Paul Murrell and others for providing that. I noted that in https://svn.r-project.org/R/trunk/src/library/grDevices/src/devPS.c a macro is defined: #define MAX_RASTERS 64, and consequently, I get Error in grid.Call.graphics("L_raster", x$raster, x$x, x$y,

Hello everyone in the forum For introducing myself I would say I have a basic knowledge of R. Now I am intended to implement a flood algorithm using R. I have some MatLab experience doing these, and as an example to explain more or less what I want, I have a m code to calculate the slope from a Digital elevation model: slope=zeros(row,col); for i=2:row-1 for j=2:col-1

Dear all, I am running R 2.8.1. under ubuntu, and I need to install the package "raster" but I get the following error: > install.packages("raster") Warning in install.packages("raster") : argument 'lib' is missing: using '/usr/local/lib/R/site-library' --- Please select a CRAN mirror for use in this session --- Loading Tcl/Tk interface ... done

This is now fixed in development on RForge, you can try it out by installing from there, or from the Github mirror with devtools::install_github("rforge/raster/pkg/raster"). (To get fixes into raster email the maintainer directly - you might not get a response but it'll be addressed). Cheers, Mike.

Hello R-Group, I am new working with netcdf files and the raster package in R.I am trying to read in a netcdf file using the package "ncdf".I am able to get the lat, lon and parameter I need and can plot using fill.contour.Ultimately, I am trying to create a .asc file to reafd into GIS.I am using the package "raster" to read the parameter.When I read in with

Hello, I have a large number of raster objects in memory, with names RH100, RH101, RH102, etc. (myobjects <- ls(pattern='^RH')). These rasters are sections of a continuous map, and I would like to combine them using the RasterObject merge tool in package 'raster.' Merge expects an input list of raster objects (outmap<-merge(x, y, ...), where x, y, and ... are raster
