Re: [R] Ggplot2 Line Problem
Hello,
Sorry, I forgot you also want the line type changed.
Remove color and linetype from the initial call to ggplot and include
aes(color = cases, linetype = cases) in geom_line. Then add a layer
scale_linetype_manual with the same name and labels to merge it with the
color legend.
dfO %>%
pivot_longer(
cols = -date,
names_to = "cases",
values_to = "count"
) %>%
mutate(cases = factor(cases, levels = c("positive", "negative",
"total"))) %>%
ggplot(aes(date, count)) +
#geom_point() +
geom_line(aes(color = cases, linetype = cases)) +
scale_color_manual(name = "Test",
labels = c("Positive", "Negative", "Total"),
values = c("red", "blue", "green")) +
scale_linetype_manual(name = "Test",
labels = c("Positive", "Negative", "Total"),
values = c("solid", "dotdash", "twodash")) +
ylim(0, 175) +
labs(x = "Date", y = "Number of Tests")+
ggtitle("COVID-19 Tests in Ohio \n (8/15/20)")+
theme_bw() +
theme(axis.text.x = element_text(angle = 30, hjust = 1),
plot.title = element_text(hjust = 0.5))
Hope this helps,

Hello,
This type of problem is almost always a data reshaping problem.
ggplot graphics work better if the data is in the long format and you
have 3 columns for counts, one column for each category. If you reformat
from the current wide format to the long format you will have a date
vector, a categorical variable and a counts variable.
In the code below just change geom_point to geom_line and the problem is
solved.

Re: [R] Best settings for RStudio video recording?
In my experience pixel count is only indirectly related to legibility on a small screen, since they may have very high pixel count yet still be poorly readable with "normal" programming font sizes. If you really want to support that then increase font size. Slide presentations have similar design principles. If you really want the multi-pane experience then I would advocate for not assuming the phones will be usable, but you can try the medium font everywhere approach and hope for the best.

Completely agree with Roy M. and do not wish to express any opinion, but this typo was too precious to ignore: "If the criteria is: Sacrificing prophets (not just theirs, but their *holding/sibling companies too*), for some public benefit(s)..." Oh gosh, I hope no prophets are sacrificed ... though I can think of some financial and political pundits who may deserve that fate Still, let's keep it to chickens or the occasional goat...

Re: [R] Best settings for RStudio video recording?
I totally agree with Roy, thank you. I hope that we can get the discussion back on OP's question (which is timely and very important, and actually not specific to the IDE). The problem is that our possibilities to test user experience are usually limited. AFAIK students could be participating via their mobile phone... I want to be able to type code, have them read along, open help-pages, discuss the help pages, and plot things. Zoom appears to send out 720p video. That is 1280 x 720 px. If I set my monitor from which I screen-share my R session to 1280px wide, does this mean I will be doing the best I can to reduce anti-aliasing artefacts and improve legibility? Or does it even matter?

Re: [R] Best settings for RStudio video recording?
May I suggest that this discussion is best left for another time and place. Some people have very strong opinions about RStudio vis a vis R, it has been discussed here before, shedding mostly heat and not a lot of light (nor do I think anyone had their mind changed), and worse the discussions have tended to move over to twitter, where twitter mobs have gone after people whose views on this subject didn't agree with theirs, to the extent of digging up any transgression that person ever committed and claiming that discredited anything they said about R and RStudio, rather than dealing with points made. I have seen people who I have reason to believe are well-meaning, decent people trying to improve R, be tarred and feathered on this subject (and this is on both sides of the discussion), I can't believe that this helps improve R, nor does it help anyone use R, which is the main point of this mail-list.

Re: [R] Hot Air Balloon Weather Briefings
Hi Philip,
My fault for assuming that what worked for the sample data would work
for the entire data set. If you run the following code:
# read the file into a data frame
phdf<-read.csv("phdf.csv",stringsAsFactors=FALSE)
print(dim(phdf))
# create a logical variable for the subsetting step
keep<-rep(TRUE,length(phdf$Speed))
# this follows the conventional for(i in ...) syntax
# mini (minute index) is the name of the variable
# that is assigned the successive values of the
# unique values in the Minute column of phdf
# here I was lazy and only dealt with the sample data
# what I should have done was to create a column
# with minute values that don't repeat
phdf$hourmin<-phdf$Hour.Z * 60 + phdf$Minute
for(mini in unique(phdf$hourmin)) {
# mark all minutes that are all zeros for deletion
if(all(phdf$Speed[phdf$hourmin == mini] == 0))
keep[phdf$hourmin == mini]<-FALSE
# but now there is another condition
# that I didn't notice (more laziness)
# drop minutes containing ten consecutive zeros
# I'll use a cheap trick for this
# if the length of the run length encoding (rle)
# of the Speed == 0 condition is less than three,
# then there can't be a broken run of zeros
if(length(rle(phdf$Speed[phdf$hourmin == mini])$length)<3)
keep[phdf$hourmin == mini]<-FALSE
}
# now drop any rows for which has marked FALSE (note all caps!)
phdf<-phdf[keep,]
print(dim(phdf))
You will see that it has removed 67 rows. This is the same as if I had
only applied the first "all zeros" condition, for there were no
unique minutes with 11 observations that contained a single non-zero
speed value. I can see that you are getting short runs of zero speeds
near the end. I assume that this is due to the balloon slowly bumping
along the ground. Often just looking at the data can suggest solutions
to problems like this.
Coincidentally I am about to email an old friend of mine whose sons
have dabbled in sending balloons high into the air and I will let them
know that they are not alone in performing this unusual practice. If I
haven't answered all your questions, feel free to let me know.

[R] Plot math symbol with string and number
Dear Helpers,
I would like to make plots with titles for different data sets and
different parameters. So a useful title should combine data name
and parameter for clarity. The following is a simplified code example with
two plots. The first title doesn't show sigma as a math symbol, while the
second one doesn't contain the s value as a numeric value - I could
manually change the s value, but when there are many different s values,
this is not a good solution. Thanks!
s <- 1
y <- rnorm(100)
plot(y, main=paste("data", "sigma=", s))
plot(y, main=expression(paste("data", sigma,"=", s)))

I do sometimes but not always and have found them useful.
