Well then:
"Using the multi-OS RStudio for teaching R seems rather less off-topic than
that."
If the query is about teaching r, wouldn't R-Sig-teaching be the right
place to post?

The jab about a "private company" detracted from your point. It is a public
benefit corporation, but either way they produce open source software that is
frequently used to introduce people to R, and the company management structure
is irrelevant.
While I would have preferred to see a question
Excellent question! I think most R courses use RStudio, so it is completely
appropriate to ask about how to help people learn R using RStudio.
I don't have a lot experience with virtual teaching, and very limited
experience with anything other than short-term workshops.
I think that there is
Way off topic. Ask at RStudio. This is **R-Help** -- help on R
programming. RStudio is a private company.

On Thu,
Folks:
I was wondering if you all would suggest some helpful RStudio
configurations that make recording a session via e.g. zoom the most useful
for students doing remote learning. Thoughts?

Hi Philip:
Both 'ncdf4' and 'Rnetcdf' should be able to download data using OPeNDAP. That
the package is using OPeNDAP is transparent to the user, other than the fact
that the "file" is an URL. Extracts are just like reading a netCDF file using
these packages, so you may have to spend

keep getting recycled to three or four websites

Short answer: perhaps
https://cran.r-project.org/bin/macosx/el-capitan/base/R-3.6.1.pkg would
work?
Dear Sir/Madame,
Could you please let me know where to find the Version 3.6.1 for MAC since I
have a package only working with this version
Unfortunately I can not find it here

While it is possible to fill bars with patterns, it is not
recommended. Fill patterns can lead to what is called the Moire
effect and other optical illusions. Depending on the fill patterns
and how they relate to each other this can cause an illusion of
movement within the plot, straight lines
Hello,
In base graphics function barplot has arguments angle and density, see
the help page ?barplot. As an example, with the same data (note that the
argument density is recycled, 2 values, one per stacked bar times the
number of unique X vakues):
barplot(Freq ~ Y + X, tbl, density =
Hi Jim,
Thanks for the hint, that makes sense and I'll arrange accordingly.
Best regards,

Thanks Rui. That's very close to what I am looking for. You use gray scales
for different categories. That would be a great idea. Could we use pattern
fill?

You should post on r-sig-geo, not here. The specific expertise you seek is
much more likely to be found there.

Without sample data and the code you've tried it's difficult to say but

Hi All,
i am very new to R and need guidance.
Need help in doing process capability Analysis for my data set (6 months of

Hi,
I would like to create percentage stacked bar with graphics package
(e.g., ggplot2) and print it in white/black. The regular option is to use
different color on the bar. Is there any way to use different background on
a bar so that we can tell on a black/white printing? For example, let my
Hi Abdoulaye,
It looks to me as though your offsets are in hours, not days. You can
get a rough date like this:
time<-c(1569072,1569096,1569120,1569144,
1569168,1569192,1569216,1569240)
time_d<-as.Date("1800-01-01")+time/24
time_d
[1] "1979-01-01" "1979-01-02" "1979-01-03" "1979-01-04"
I have dataset with time sine 1800-01-01 and extracted data from 1981 to
2019 and used these lines for the data conversion:
> time_d <- as.Date(time, format="%j", origin=as.Date("1800-01-01"))
> time_years <- format(time_d, "%Y")
> time_months <- format(time_d, "%m")

Hi
I am not sure if I understand correctly. You want to change starting days to
some common value?
It seems to me that you actually want start at zero date and continue in each
dataset regardless of actual starting date. If it is the case, I would use day
numbers like in these examples
