Hi Nick,
First off, I would suggest going to:
https://cran.r-project.org/web/views/Spatial.html
also have a close look at
https://journal.r-project.org/archive/2017/RJ-2017-067/RJ-2017-067.pdf
And you might also consider the use of GRASS GIS, which interfaces with R
pretty seamlessly:

Paul,
I think your point you need [to] spend at least a few hours a week on
it is key. Since I am not doing statistics daily, more in fits starts
as my latest project -may- require, my approach has been more task
oriented. A less-than-ideal approach. So, I think your suggestion is

Dennis,
Thank you for the suggestion, but I get this error:
t.test(MAE ~ type,data=data)
Error in t.test.formula(MAE ~ type, data = data) :
grouping factor must have exactly 2 levels

I am using the command: qplot(date,MAE,data=data,facets=INTERVAL~type)
which works fine except that the dates for my date axes are crunched
together so much that they are unreadable. I can not find an option that
I can set that will automatically reduce the x-axis labels to fit the

Thanks; that's just what I needed!

Hi:
ggplot2 works with dates of class date and times of class POSIXct.
See scale_x_date(), which is discussed in section 6.4.2 of the ggplot2

Aneeta,
You will have to have a seasonal component built into your model,
because the seasonal variation does matter, particularly -where- you are
geographically (San Diego, Chicago, Denver, Miami are very different).
Generally, there is a sinusoidal daily temperature variation, but

Esmail,
Very nice; thanks!

Oliver,
You may consider looking at the climatol: Some Tools for Climatology
(http://cran.r-project.org/) contributed package. This may come close to
what you're looking for. I would suggest using R with GRASS GIS
(http://grass.osgeo.org/), which is a powerful combination.

Stephen,
I don't have anything or know of anything in R to do this. But, we download
USGS streamflow data routinely. I have a Perl script that will reformat the
downloaded data into a R-importable format (basically two columns date/time
flow value). Are you interested in mean daily or
I have data that I read in using:
data-read.table(RAVK2.obs.data,sep=\t)
'data' looks like this:

1 2009-03-25 06:00:00 12.86
2 2009-03-25 12:00:00 12.80
3 2009-03-25 18:00:00 12.76
4 2009-03-26 00:00:00 12.68
5 2009-03-26 06:00:00 12.66
6 2009-03-26 12:00:00
I don't think At least one of the participants in the 2004 thread
suggested that it would be a good thing to track the numbers of
downloads by package. is reasonable because I download R packages for 2
home computers (laptop desktop) and 2 at work (1 Linux 1 Mac). There
must be many such

Yes, that's what I was referring to as well…

I certainly had that same impression of mischief making — I would call

contributors. Mischief making indeed!

Joris,
I found this (http://ceae.colorado.edu/~balajir/r-session-files/) on the web.
It will do exactly what you want. Get the files:
myboxplot-stats.r
myboxplot.r
Leesferry-mon-data.txt = example data
The usage is:
#Boxplots
#Source the ‘myboxplot’ codes from Balaji’s directory.
