Hi Avi,
I am not sure that the R-help mailing list is a suitable channel for
advertising R-related tools... But given you mentioned Positron
(https://github.com/posit-dev/positron), which is based on VSCode, it is
worth calling out that a free, open-source, community-maintained, very
feature rich R extension
(https://code.visualstudio.com/docs/languages/r) already exists in VS
Code for years.

Just to be clear, Denis, I am not in any way associated with anybody or
anything and just read about it on a news feed not from POSIT directly.
I am aware it is based on existing functionality and have used possibly similar
editors for other languages. I did try possibly one touted by Microsoft years
ago (perhaps what you are referring to) but felt no need to keep using it at
the time. What I am interested in is hearing from others who have opinions,
perhaps after having tried it.
And there is a trend I have noted where some development environments have been
moving towards multiple language support including at times integration between
languages. RSTUDI, itself, has been supporting a number of languages besides R
and that is one reason it changed names for the company. What they are offering
now, and I am not clear what they are adding or changing, looks like an attempt
to evolve along such lines.
Python versions typically have shipped with a fairly rudimentary IDLE program
you can use as a sort of editor. Plenty of other add-ons are available
independently. As noted, RSTUDIO now is such an add-on for python too.
R, as far as I know, has not taken that route and you get just the language
alone and the community is free to use anything else they want. RSTUDIO is one
of many but arguably, quite a few here have used it. Many versions are
currently FREE and some paid versions may have more functionality. I am
wondering if this new product is going to change things such as fee structures
or even eventually replace ...

The gap I see is in the database engine monitoring.
MySQL has discontinued development of Workbench. Percona Monitoring and
Management seems nice, but not as integrated in IDE as I would prefer.
A Positron tool proposed by the vendor is positioned as a data science
tool. The ability to know if any R work is killing the DB by overloading
it is still a missing piece of the IDE picture without running multiple
code monitoring sections in watch windows.

Dear Richard,
I could not extract the data at all.
But what I found is that, the data stored in the grib file converted into
raster layer, and as I had 6 met parameters for a complete year (6 × 365 ×
24) the raster layer has 52,560 layer. The first layer belongs to the first
parameter for the first hour and second layer to the second parameters for
the first hour..... .
And again the seven layer belongs to the first parameter for the second
hour and the layer number 8 belongs to the second param. for the second
hour.... and this cycle is repeated until the layer number 52,560.
I think writing a function to extract these data can be helpful. For
example writing a function to extract the data number 1 and 7 and 13 and
... store in the first column and data number 2,8,14, .... stor in the
second column and doing this for other parameters to complete the table and
eventually create a column for Date.
Can you help me to write a function.
Sincerely

OK. The problem is that the extract() function didn't know what to do.
What does the documentation for 'extract' say?
The error message seems to say that it is not defined for first argument
being
a SpatRaster and second argument being of type character.
(By the way, I'm having trouble updating the terra package in Ubuntu 22.04.
That's why I'm not trying any of this out.)
Here's what ?extract starts with:
Extract values from a SpatRaster for a set of locations. The
locations can be a SpatVector (points, lines, polygons), a
data.frame or matrix with (x, y) or (longitude, latitude - in that
order!) coordinates, or a vector with cell numbers.
It does NOT say that the set of locations can be a vector of strings.

I'm now inclined to go with 'search for "convert GRIB to CSV".
https://confluence.ecmwf.int/display/CKB/How+to+convert+GRIB+to+CSV
is the first line. I know that's not an R solution, but using software
specifically developed for encoding, decoding, extracting, &c GRIB file
by the
European Centre for Medium-Range Weather Forecasts and actively
maintained, with an example page showing how to do it, sounds like a
good approach.
One of the major things about R is that from the very beginnings of S
it was intended to be used with other tools. We have R communicating
with Python and Tcl and dear knows what. Getting a specialised tool
to do its thing is very much part of the R "way".
Or there's gribr https://rdrr.io/github/nawendt/gribr/man/gribr.html
which wraps ecCodes in R.
I still don't understand what "doesn't work" means. Which step goes
wrong and how does it misbehave?

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 exported file as excel contains 7 columns (Date + 6 met
parameters).

I have no account at that service, so could not download a sample for

it in a message? Which parameters are you extracting? When you say
"it didn't work", what actually happened? Which step went wrong and
how?

Dear all;
I have downloaded meteorology data from "

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 first col represents Date, 2nd
represents Temperature and so on.
Is there any way to do it?
I used these codes but did not work:
# install.packages("rNOMADS")
library(rNOMADS)
# Read GRIB data
grib_data <- ReadGrib("C:/Users/admin/Downloads/Met.grib")
# Convert to a data frame
grib_df <- as.data.frame(grib_data)
# Write the data frame to a CSV file
write.csv(grib_df, file = "output.csv")
I would be more than happy if anyone could help me.

Hopefully this question elicits a simple answer.
I am in Europe at present. When I issue the command:
Sys.Date()
I would like to be able to obtain the value for Pacific time (which differ for
the first 9 hours of the day),
I would like the process to be automatic, regardless of where in the world I am

By the time the value of Sys.Date() is created, it's too late to
discern between Europe and Pacific time. The Date class is intended to
store the integer number of days since 1970-01-01:
unclass(Sys.Date())
# [1] 19902
Only by preserving the time we can get a timezone-dependent date:
format(Sys.time(), '%Y-%m-%d') # uses the current time zone
# [1] "2024-06-28"
format(Sys.time(), '%Y-%m-%d', tz = 'Asia/Vladivostok')
# [1] "2024-06-29"
