Hi: I am working with someone remotely to allow them access to our data. The follow command using "download.file" works perfectly on my Mac: > > download.file(url="http://oceanwatch.pfeg.noaa.gov:8081/thredds/ > wcs/satellite/AG/ssta/14day? > request=GetCoverage&version=1.0.0&service=WCS&format=NetCDF3&coverage= >

Hi all -- I am working on 64-bit Windows XP. I'm not a very technical person when it comes to the command line stuff, so please forgive me if this is a stupid question. I have a bunch of HDF files, and I want to dump a single PM25 data layer from each file to .txt by invoking ncdump.exe from system(). Here's a sample command string: "C:/ncdump -v PM25 C:/01aug2010.hdf >

How to programmatically (i.e., without no or minimal handcoding) copy a netCDF file? (Without calling > system("cp whatever wherever") :-) Why I ask: I need to "do surgery" on a large netCDF file (technically an I/O API file which uses netCDF). My group believes a data-assimilation error caused a data variable to be corrupted in a certain way, so I'm going to

Hello, I am new at using R. I would like to use the following functions of the "clim.pact" package: ncdfcont and retrieve.nc I have installed the package "clim.pact" in Rstudio. I have downloaded the "ncdf pack" from unicar (including ncdump and ncgen). The ncdf file I'm working on is called "essai2.nc" Here is what I get, when I type the command

Dear all, I have a file which I've converted from NetCDF (.nc) to text (.txt) using ncdump in Unix (as I had problems using the ncdf package to do this). The first few rows (as copied and pasted from the Unix console) of the file appear as follows: _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _, _,

If you are a user of the R package "xtractomatic", I have a new development version available, as well as a test version of the package "rerddapXtracto". The biggest changes are functions that can take the output of any of the data download functions and quickly map the data. These functions use the package "plotdap". Also, a lot of the code in the development

Dear List, Is there a color palette avaliable similar to what is used in satellite ocean color imagery? I.e. a gradient with blue on one end and red on the other, with yellow in the middle? I have tried topo.colors(n) but that comes out more yellow on the end. I am looking for something similar to what is found on the CoastWatch web page:

Can someone help me out with a "small" problem? I've started using netcdf files recently, and I want to extract the grid id and also the coordinates from a HIRHAM netcdf file. I know how to extract a slice of dataset both in space and in time and I also know the area that this file should cover, however I have no idea regarding the reference for both LAT/LON and RLAT/RLON. I tried

Hello, I have been having difficulties opening netcdf files using the netcdf library. I am able to successfully open the file and I can determine the names and size. However, when I try to read it I receive an error. Reading the documentation, I am wondering if this might be due to a difference between netcdf version 2 and more recent netcdf format? I've tried using different values for the

System: Linux kernel 2.6.15 Ubuntu dapper R version 2.5.1 ESS 5.2.11 on Emacs 21.4.1 ------------------------- Colleagues Having read the posts on producing perfect graphs in R, or using inkscape to edit R graphics output, I have a related question. Lately I am publishing in a journal that is very picky about their graphics formats. It is more efficient for me to get the final picky details

Hi all, I have played a bit with the "reshape" package and function along with "melt" and "cast", but I feel I still don't have a good handle on how to use them efficiently. Below I have included a application of "reshape" that is rather clunky and I'm hoping someone can offer advice on how to use reshape (or melt/cast) more efficiently. #For this
