Dear List Members, I need some help about programming in S language. My problem is as follows: I have meteorological data (about rainfall measurement each day from 1989-2002), say like http://www.angelfire.com/ab5/get5/data.rainfall.txt or http://www.angelfire.com/ab5/get5/R.rainfall.txt in a sequence of 0(denoting dry day)'s and 1(denoting wet day)'s. I want to construct a frequency distribution tabl...

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.

Dear HelpeRs: I have a data set in the following format, which will be familiar to those of you working with NCDC climate data. Example: Year <- rep(1:3, each = 3) Year <- c(Year,Year) ID <- rep(1:2, each = 9) Jan <- runif(18, min = 0, max = 20) Feb <- runif(18, min = 0, max = 20) Mar <- runif(18, min = 0, max = 20) var <- gl(3,1,18,label =

Dear r-help, I have a radar data file in the following format: nrays for (1 to n_rays) { some_data_info for (1 to n_gates) { some_data_info} } N_rays=360 and n_gates=950 The data looks something like: Header line1 Ray1 header gate1 var1, var2,.....,varN ... gate950 var1, var2,.....,varN Ray2 header gate1 var1, var2,.....,varN ...

...R1.8. Is there a way to update to R1.8 while in R1.7 in the same manner that I can use "update.packages", or do I have to install R1.8 in a separate directory and re-install the many packages I have already installed in R1.7?

Richard, Many thanks for your email. I had attached the grib file to the original email to R help team but it seems you did not receive it. Unfortunately, I do not know how to reduce the volume or extract some of the grib file data to send it for you. The file has the volume of 6 Megabyte. I can send it by email. The file has 6 met parameters and Date (day/month/year hour:minute). I want the

Hi all: I have a question on how to go about creating a correlation matrix. I have a huge amount of data....21 variables for 3471 times. I want to see how each of the variables correlate to each other. Any help would be appreciated, including which package and which functions I should use to do this. Thanks, Jessica Higgs Masters Student Department of Meteorology Penn State University

Hello, are there people outside who use R for analysis of wind-measurement data (meteorological or for planning of wind power stations)? Are there already scripts/modules available for analysing and displaying/plotting wind data in the way it is done in projection/planning of wind power stations? If not, would it be of interest to use R for this, and therefore adapt data-logger output to...

Hi everybody, I have a question about a special way to use rsync. Is it possible to use rsync for retrieving files without a local dir compare? There for rsync needs to know in a catalog or logfile what was already retrieved. Why I need that: We receive meteorological data from a remote server to a local directory (every 5 min). If the data is here, it is imported by a special software, after the import it will be deleted from that directory. The deleting can't be disabled. Normally I would say, ok download all again, but we get 80GB data per day. If rsyn...
