Converting .grib to excel file
Dear all; I have downloaded meteorology data from " https://cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-single-levels?tab=form" as .grib format. It has hourly data of a complete year (every hour of every day of 12 months) and has 6 meteorology parameters. The file has been attached. I am trying to convert it to an excel file that puts every parameter in a separated column. For instance, the...

Isolines in vector format
Dear R users, I am working with netcdf data of NCEP/NCAR Climate Reanalysis. R does have capability to draw isolines using "contour". However, I need not to draw but to export contours in any vector format. Is it possible? Thank you.

who happenly read these two paper Mohsen Pourahmadi (biometrika1999, 2000)
http://biomet.oxfordjournals.org/cgi/reprint/86/3/677 biometrika1999 http://biomet.oxfordjournals.org/cgi/reprint/94/4/1006 biometrika2000 Hi All: I just want to try some luck. I am currenly working on my project,one part of my project is to reanalysis the kenward cattle data by using the method in Mohsen's paper,but I found I really can get the same or close output as he did,so,any one who have happenly read his paper,got any idea how he got the LS estimates of gamma. he assumed the autoregressive phi_tj satisfy the cubic function on lag...

Std errors in glm models w/ and w/o intercept
I am doing a reanalysis of results that have previously been published. My hope was to demonstrate the value of adoption of more modern regression methods in preference to the traditional approach of univariate stratification. I have encountered a puzzle regarding differences between I thought would be two equivalent...

uncertainty principle is untenable !!!
...x or dPx dx ~ h. (5) For more than minimum uncertainty, the "greater than" sign may added. Except for the factor of 4pi and an equal sign, this is Heisenberg's uncertainty relation for the simultaneous measurement of the position and momentum of an object . Reanalysis To be seen by the microscope, the gamma ray must be scattered into any angle within the cone of angle 2A. The microscope can resolve (that is, "see" or distinguish) objects to a size of dx, which is related to and to the wavelength L of the gamma ray, by the expression: dx = L/(2sinA)...

netcdf
Hi All, I'm very knew to R. I downloaded and am running it on my redhat so that I can use the clim.pact package. Everything is downloaded and installed correctly. When trying to read a netcdf file from the NCEP/NCAR reanalysis dataset using retrieve.nc I keep getting errors that the number of dimensions are wrong. If I use x.1 <- retrieve.nc("geopothgt.nc") I get the above error. this file is a subset created from the NCEP website with only the 500 mb level I've tried both force 365.25=TRUE daysayear...

problem with loop to put data into array with missing data for some files
...(and making it's output into an data.out array would be NA) and moving onto the next year/month in the loop to carry on filling data.out with real precipitation data. The situation so far: I downloaded 50 years worth of GRIB data files from the NCEP data site http://nomad3.ncep.noaa.gov/pub/reanalysis-1/month/grb2d.gau/ I then created a loop in R to read each month of each of the 50 years worth of files and only extract the precipitation records using wgrib and grep as show in the code at the end of this message. I had to use grep to extract the PRATE records each time, as unfortunately with...

Please help
Dear All, I am a research student in environment. I have only little programming knowledge. I am currently doing the last project about rainfall impact on ground water quality in an area. It happens that I have to use R to read rainfall data (3 dimension) from ASC file (*.asc), and then write them into one NCDF file (*.nc). I have been working very hard on study R, but I
