Re: [R] Best settings for RStudio video recording?
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 that was open to any presentation format, forbidding discussion of how to teach R just because the query happens to limit itself to RStudio seems excessively narrow to me. I have been frustrated by the fact that there is no r-sig-windows, since I find myself uncomfortably discussing OS-specific issues on R-help for which there is no better place to forward them. Using the multi-OS RStudio for teaching R seems rather less off-topic than that. On August 13, 2020 3:15:31 PM PDT, Bert Gunter wrote: >Way off topic. Ask at RStudio.

Re: [R] Best settings for RStudio video recording?
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 tremendous value, during the 'in person' portion of a course, in doing interactive and even 'ad hoc' analysis, perhaps especially handling the off-the-wall questions that participants might raise (when I have to struggle to figure out what the R answer is, and then convey to the attendees my thinking process), and making all kinds of mistakes, including simple typos (requiring me to explain what the error message means, and how I diagnosed the problem and arrived at a solution that was other than a pull-it-out-of-the-hat miracle). With this in mind, I try to increase the prominence of the console portion of the RStudio interface. I place it at the top left of the screen (this might be a remnant of in-person presentations, where the heads of people in front often block the view of the lines where code is being enter; this is obviously not relevant in a virtual context). Usually I keep the script portion of the display visible at the bottom left, with only a few lines showing, as a kind of cheat sheet for me, rather than for the students to 'follow along'). I use a large font, which I think helps in both virtual and physical sessions in part because it limits the amount of information on the screen, causing me to slow my presentation enough that the students can absorb what I am saying. Perhaps as a consequence of the limited screen real-estate, students often ask 'to see the last command' so I now include in the right panel the 'History' tab. The division is asymmetric, so the console continues to take up the majority of screen real estate. The end result of a sequence of operations is often a pretty picture, but since this is only the end result and not the meat of the learning experience I tend to keep the plot window (lower right) relatively small, and try to remember to expand things at the time when the end result is in sight (so to speak;)). I hope others with more direct experience are not dissuaded by Bert's opinions, and offer up their own experiences or resource recommendations.

Re: [R] rNOMAD package
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 some time learning how to do that. It is possible that 'tidnyNC' can also do OPeNDAP, I am just not certain that. -Roy > On Aug 13, 2020, at 8:59 AM, Philip wrote: > > Daniel Bowman wrote a wonderful package to access National Weather Service > data with R. > > Unfortunately I stuck trying to download archived Rapid Update Forecasts > (RAP) going back into 2016.

Re: [R] stacked bar on single-color printing
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 appearing curved, and
distorting of lengths/positions. Fill patterns (through the
illusions) can subtly move the observer's eye away from the important
parts of a graph and make it hard to focus on the parts of the graph
that are most important. Google for phrases "Moire effect graphs" and
"optical illusion diagonal lines" for some examples.
Perhaps a dot chart (using symbols instead of colors/greyscale/fill
patterns) would be a better option than a bar chart for your case.

Re: [R] stacked bar on single-color printing
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 = c(10, 0))
Hope this helps,

[R] Error with sf ordinary kriging after creating grid
I want to perform ordinary kriging of temperature (UTCI) data in Nigeria with
sf and gstat packages. However, after fitting the variogram model and creating
a grid for the region, the krige function returns this error:
Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘krige’ for signature
‘"formula", "sfc_POINT"’
What am I doing wrong? Here is my code:
library(gstat)
library(sf)
sf_data <- st_as_sf(x = data, coords = c("longitude", "latitude"), crs = 4326)
#VARIOGRAM
vgm_utci <- variogram(UTCI~1, sf_data)
utci_fit <- fit.variogram(vgm_utci, vgm("Mat"), fit.kappa = TRUE)
#CREATE GRID
nigeria <- read_sf("./Igismap/Nigeria_Boundary.shp")
nigeria <- nigeria$geometry
nigeria.grid <- nigeria %>%
st_make_grid(cellsize = 0.1, what = "centers") %>%
st_intersection(nigeria)
#UTCI ORDINARY KRIGING
utci_krig <- krige(formula = sf_data$UTCI ~ 1, nigeria.grid, model = utci_fit)
When plotted, the grid and the variogram model look fine. I have attached data
and shapefile. Thank you so much in advance,
Nicola

Re: [R] stacked bar on single-color printing
Hello,
Without sample data and the code you've tried it's difficult to say but
are you looking for something like this?
set.seed(2020)
df1 <- expand.grid(X = factor(1:5), Y = LETTERS[1:2])
df1 <- df1[sample(nrow(df1), 100, TRUE), ]
library(ggplot2)
tbl <- as.data.frame(table(df1))
ggplot(tbl, aes(X, Freq, color = Y, fill = Y)) +
geom_col() +
scale_color_manual(values = c("black", "black")) +
scale_fill_manual(values = c("white", "gray70")) +
theme_bw()
Hope this helps,

[R] Binomial PCA Using pcr()
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 data) given in below format: Date | Opportunities | Defectives | DefectivesInPercent I searched and found that pcr() from QualityTools package can be used for this purpose. The USL is 2% defectives. MyData = read.csv(file.choose()) #select CSV file that has data in above mentioned format. x <- MyData$DefectivesInPercent pcr(x, distribution = "negative-binomial", usl=0.02) I get error message as: Error in pcr(x, distribution = "negative-binomial", usl = 0.02) : y distribution could not be found! Please advise, how to proceed?

Re: [R] date conversion problem
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" "1979-01-05"
[6] "1979-01-06" "1979-01-07" "1979-01-08"

[R] date conversion problem
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")

"6096-04-20"
As you see these gregorian dates are unrealistic and wonder what I am doing
wrong?
The time from the raw file in Jd are like this:
> time
[1] 1569072 1569096 1569120 1569144 1569168 1569192 1569216 1569240etc.
Hope hint and/or suggestion to solve this.

Re: [R] add trailing dates with rbind
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
> x <- seq(as.Date("2020-03-01"), by=1,length.out=20)
> x-x[1]
Time differences in days
[1] 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19
> y <- seq(as.Date("2020-03-01"), by=2,length.out=10)
> y-y[1]
Time differences in days
[1] 0 2 4 6 8 10 12 14 16 18
> z <- seq(as.Date("2019-03-01"), by=2,length.out=50)
> z -z[1]
Time differences in days
[1] 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 42 44 46 48
[26] 50 52 54 56 58 60 62 64 66 68 70 72 74 76 78 80 82 84 86 88 90 92 94 96 98
