if() for() { }
Dear R'helpers, I guess the solution is trivial but despite some hours of testing and looking at the doc, I was unable to fix the following problem. I want to do either: for (i in 1:lat) a[i,which(a[i,]==0] <- NA or: for (i in 1:lat) a[i,which(a[i,]==-9999|a[i,]==9999|a[i,]==9998|a[i,] ==-9998)] <- NA if the word "Time" is or is not present in variable

translating IDL to R
I would appreciate * guidance regarding translation of IDL routines to R, generally * assistance translating two IDL routines to R, specifically Why I ask: I'm slowly learning how to do atmospheric modeling. One language that has been been popular in this space is IDL http://en.wikipedia.org/wiki/IDL_(programming_language) which unfortunately is proprietary (not to mention butt-ugly, IMHO

Extracting subset from netCDF file using lat/lon and converting into .csv in R
I have a series of nertCDF files containing global data for a particular variable, e.g. tmin/tmax/precipiation/windspeed/relative humuidity/radiation etc. I get the following information when using *nc_open* function in R: datafile: https://www.dropbox.com/s/xpo7zklcmtm3g5r/gfdl_preci.nc?dl=0 File gfdl_preci.nc (NC_FORMAT_NETCDF4_CLASSIC): 1 variables (excluding dimension variables):

ggplot2 problem
Dear all, We are trying the code from the paper (http://www.jstatsoft.org/v40/i01/) to build stars for each point on the map (plyr package). It uses ggplot2 package and works fine for ozone data but we can't get it work for our data (probably due to misunderstanding of some issues). Our data is SO2 time series for each point on the map with 0.25 degrees step. It has both NA, negative and

Extracting subset from netCDF file using lat/lon and converting into .csv in R
Two questions: 1. Is the order of the dimensions shown what is shown if you look at str(ncin) - I mean shown at the end where it describes the variable and its dimensions? 2. Is you problem how to subset the netcdf file, how to write to the .csv file, or both? -Roy > On Aug 28, 2017, at 2:21 PM, Eeusha Nafi <eshad002 at gmail.com> wrote: > > I have a series of nertCDF files

how to read hdf files under R?
Hi! I am trying to install in my R environment the rhdf5 package and library but it seems to have vanished from either the CRAN or BioConductors sites. Can you tell me where it would be possible to find it or any R library (or function) able to read hdf files?

Problem with distributing data in package.
Hi List, I am building a package for a client to help them create and perform analyses against netcdf files which contain 'a temporal stack' of grids. For my examples and test cases, I create an example dataset in code (as this is a lot more space efficient than providing raw data). The code creates a netcdf file in tempdir() and an object of class 'ncdf' in the global namespace.

REading the netCDF format into R
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,

negate the regexp in validates_format_of
Railsters: ActiveRecord''s validation system puts other database systems to shame. However, the newbies might not know how to write a regexp that excludes a match, instead of tests for it.

The R "fork"
Hello, I would like to call a function that can take infinite time to be executed in some circumstances (which can not be easily detected). So, I would like that once the function is being executed for more than two seconds it is stopped. I have found documentation for timers but i did not found how to "kill" a function. Moreover, I would like not to change the function code (it should

Cannot enable "Enable advanced printing features"

REGRESSION: New "megatec" driver does't work for UPS that was managed by old fentonups driver
Hi there, A couple years ago, I had patched the "fentonups" nut driver to allow it to work with my Unitek Alpha 500 UPS. My patch had been accepted and incorporated in the standard fentonups driver. I have had no time to stay involved in the "nut" project since (and besides this I'm not a developper...). 2 days ago I upgraded from Ubuntu Gutsy to Ubuntu Hardy and got

wxruby-swig 0.0.12 is up
This one includes the latest App.cpp which includes the Mac fix from Nick. I thought it was in 0.0.11, but it wasn''t. It also adds support for "stock objects", like colours, pens, and fonts. This turned out to be quite challenging, but I''m happy with the solution. It only took a few days :-/ Kevin
