Re: [R] opening nimroad tar gz files in R

2022-09-15 Thread Eric Berger 
Is there a way to download a file from that site without registering for
the site?
If you have a unix/linux shell, what does the 'file' command output?

$ file foo.gz

[R] opening nimroad tar gz files in R

2022-09-15 Thread Nick Wray 
Hello

I am trying to download data sets from the 1 km Resolution UK Composite
Rainfall Data from the Met Office Nimrod System

Eg

CEDA Archive Web Browser

/badc/ukmo_nimrod/data/composite/uk-1km/2004

I can download an individual file (there are lots for each year) as a
.gz.tar and then it appears as a TAR file in the directory I am using.

I have then used the instruction untar() (targeted on the correct
directory) and what this produces is about a dozen these files which are
labelled as .gz files.  They appear in the same folder as the original TAR
folder but as R files (ie although they have .gz in the name they have the
R icon next to them as do any R progs which I have).  I can’t open them
though as R progs (which I don’t really think they can be) and trying to
just takes me back to the R studio interface.

I’ve tried  -- read.table (gzfile
("metoffice-c-band-rain-radar_uk_200404062250_1km-composite.dat.gz")) but
that just gives a load of error messages and I haven’t found any other way
of opening them as .gz files.

I’m rather baffled – can anyone make any suggestions?  Thanks Nick Wray

Re: [R] Overlapping barplots and lines

2022-09-15 Thread Jim Lemon 
Hi Stefano,
The bar x centers are returned by the barplot function. You can also
use the barp function (plotrix package) that places the bars at unit
intervals by default.

Can you bring up R in a shell? Do you get the same message?

This is a bit useful. The crash is happening in Rmpi:::.onLoad() during
the first line of the script, library(Rmpi), and the reason is that
something takes the number 1 and tries to dereference it as a pointer.

Rmpi's .onLoad does a number of different things [*], and the crash is
happening inside some C code anyway, so we need the debugger.

> (gdb) quit

In order to get useful information from GDB, you need to type "run" in
the GDB prompt (without the " quotes) and reproduce the crash (for
example, by running library(Rmpi)). Once the R process crashes, you
will return back to the GDB prompt, where you'll need to run "bt full"
(again, without the quotes). After that you can quit.

[R] Problem with installing packages in R

2022-09-15 Thread Farah Al Saifi 
Dear Sir/Madam

After the update of the new version of R 4.2.1, an error message ( Error in 
nchar(homeDir): invalid multibyte string, element 1)  appears every time i open 
RStudio. Also the following warning message appears in the console: In 
normalizePath (path.expand(path),  winslash, mustwork): 
path[1]="C:/Users/41784/oneDrive - Universit�t z�rich UZH/Dokumente": the 
system cannot find the given path.

I would be glad, if you can tell me the solution for this problem. Thank you 
for your consideration.

Best,
