similar to: missing values in 'ncdf', integer versus byte

dear I was lokking for a solution or an example on the internet for quite a time but since haven?t found an answer yet, I'd like to ask a maybe to simple question: I have a large ncdf-file with five dimension. temperature (t2m), the variable against, lat, lon and time. (height is included as well) the structure is [1] "file C:/RDaten/t2m.ETH.HC_A2.nc has 5 dimensions:" [1]

Hello, I'm a complete newbie to R so sorry if this is too basic..:-S I have to modify some scripts someone else did to make it work with my data. For some reason, one of the scripts which were supposed to work is not, and I get the error message "number of items to replace is not a multiple of replacement length". The script is this one: *open_lpj_nc_gpp <-

Dear All, Can anyone please let me know how exactly ncdf deals with NaN. I am trying to pass in a vector of data that has some NaN in it, into a variable in NetCDF. dimX <- dim.def.ncdf("X","count",(1:6)) dimY <- dim.def.ncdf("Y","count",(1:3)) var1 <-

Dear all, I am attempting to convert 10 NetCDF files into a single NetCDF file, due to the data input requirements of a model I hope to use. I am using the ncdf package, version 1.6. The data are global-scale water values, on a monthly basis for 10 years (ie. 120 months of data in total; at present the data are separated by year, with 12 months of data in each file - mrunoff_1986 through to

Dear Colleagues: Through your help an R related installation issue was resolved, but I now have the following usage issue. On any "get.var.ncdf" usage I am seeing: Error: in routine alloca() there is a stack overflow: thread 0, max 535822282KB, used 0KB, request 24B The same error is posted on a file as small as 50MB and as large as 500GB, with ulimit set to unlimited. I

Dear all For a model I need to combine several netCDF files into one (which works fine). For better overview I'd like to delete/remove some of the attributes. Is there a simple way doing this? I'm using the package netcdf4, which creates an object of class(nc) = "ncdf4". It seems that for earlier versions of netcdf objects, there was the function att.delete.nc{RNetCDF}. But

I would like to open an existing netCDF file and add a variable to it. I am using the ncdf package. This test code gives the idea of what I am trying to do: library(ncdf) print('here we go') print('first, construct netCDF file') t<-dim.def.ncdf('t','',1:1,unlim=T,create_dimvar=F) print('defining first vars')

Dear Marc Thanks for your remark. I don't want to use both packages. I mentioned the package RNetCDF to show that there is a similar function I' d like to use.

Hi Marc That's a workaround I can use. Thanks. I'm a newbie regarding netCDF data. Is there any information I'm losing when switching between the packages?

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

Dear all Im new in R I have a necdf data set that I want to plot : this is my data set [1] "file Tmax.DJF.daily.1981_1999.echama2.nc has 4 dimensions:" [1] "longitude Size: 127" [1] "latitude Size: 110" [1] "ht Size: 1" [1] "t Size: 1680" [1] "------------------------" [1] "file Tmax.DJF.daily.1981_1999.echama2.nc has 1

Dear All, I recently got a 64bit machine and had netcdf-3.6.2 installed. Then I tried to install ncdf package but got the following error message when using netcdflib: gcc -std=gnu99 -I/home/ljin/share/R-2.6.1/include -I/home/ljin/share/R-2.6.1/include -I. -I/usr/local/include -fpic -g -O2 -c ncdf2.c -o ncdf2.o gcc -std=gnu99 -I/home/ljin/share/R-2.6.1/include

Hi! I have been coding a C-program which will read data from the netCDF format (a commonly used file format in the geophysical research community: see Unidata's URL for explanation: http://www.unidata.ucar.edu/packages/netcdf/), and have got to the point where I don't know what the error message mean. The C-program is called nc2r.c. When compiling the code, I get a number of warnings,

Hi guys, I need your help!! My goal is to make a csv file from ncdf file.

Happy 1999! I've been celebrating the holidays by (finally) getting to the port of our S+ NetCDF routines to R, which I'm trying to make into a library. At the moment, there are two issues I'd appreciate advice on: 1. Is support for mode "single" data planned anytime soon in R? A lot of our NetCDF files contain "single" data and having to coerce into

Hi, I'm trying to read a subset of a netcdf file into R, but although I'm relatively experienced using R, I'm still new to netCDF files, so this may be a very simple/stupid question! I've included an example of the type of file I'm looking at here. www.met.reading.ac.uk/~swp06hg/ccd1983_01-dk1_20.nc (~7Mb) It's a 2D array of the variable CCD along with its lat and

Hi: Russ Moffit of our Honolulu Lab has made a modification to the R netcdf package 'ncdf' so that it can access remote netcdf files using OPenDAP (http://www.opendap.org). The package works on Linux, and with help from Don MacQueen was also ported to Macintosh OS X. We have had a lot of demand for this to be ported to Windows also, but it is beyond our capabilities.
