Re: [R] ggplot2 with an arbitrary number of curves from geom_function + legend?

[Jeff Newmiller]

Well, the ggplot2 CRAN page [1] points people to [2], which in turn points out 
that support can be found on the RStudio community forums and StackOverflow, so 
there is a path from here (where contributed packages are off-topic per the 
Posting Guide) to getting help.

I will point out that the canonical solution is definitely to put all of your 
data into one long-form data frame and use a factor column to distinguish 
aesthetics (one google result is [3]) ... loops really don't work well to add 
layers to ggplots.

But yes, if you have further questions on a contributed package, do follow the 
breadcrumbs from CRAN for sources of help, and come back when your question is 
about the R language.

Re: [R] ggplot2 with an arbitrary number of curves from geom_function + legend?

[Avi Gross via R-help]

I would reply but since ggplot was mentioned, I must abstain. ;-)

I will say that you can use ggplot in a loop in some cases if you do this:

p <- ggplot(...) + ...

Then you can in your loop keep adding to p as in:

p <- p + geom_whatever() + ...

You do at some point need to make p print itself and generate a graph. Until 
then, it can be amended, albeit some changes undo or overwrite earlier ones if 
not done carefully.

Having said all that, there is often a way to do a kind of looping within 
ggplot by say grouping your data and having it draw things grouped, or say 
making multiple vertical (or horizontal) lines by supplying a vector of 
positions.

But as noted, this is not considered a good place by some to discuss this, so 
forget I said anything.

Subject: [R] ggplot2 with an arbitrary number of curves from geom_function + 
legend?

Dear R-help,

I am trying to create a ggplot with an arbitrary number of curves + legend.

The plot should contain:
1. data points + a line that is either user defined *or* represents the median 
of the data points
2. an arbitrary number of confidence intervals (CIs) around the line, where the 
CIs are defined by a function

#1: this is easy enough
#2: I don't know how to combine this with #1

I can write #2 as a loop (see below) but it is then seems to be impossible to 
get ggplot to do a proper legend.

The challenge I have seems similar to this problem:
https://stackoverflow.com/questions/12169289/ggplot2-fail-to-apply-color-with-scale-fill-manual-inside-a-loop

Re: [R] tidying up

[Jeff Newmiller]

FWIW my brief answer to your brief question is "of course" it is okay. The real 
problem however are the questions that can only be answered by people with 
detailed understanding of non-R-related issues, such as the workings of the 
custom interactive graphics device used by RStudio or the broken behavior of 
some random GitHub-hosted package. There are a continuum of possible "degrees 
of relevance" that a question can have to the topic of a given discussion area 
(e.g. web forum or mailing list). The people who don't use RStudio don't gain 
benefit from wading through discussions that only have relevance to that 
tangential topic, and the more of that there is the lower the signal-to-noise 
ratio is from their perspective... and the sooner they leave. Ideally we will 
be kind in our redirection of the uninitiated, but an actual answer may not be 
feasible here... going elsewhere for a specific question should not be viewed 
as a negative outcome.

Since there are various interpretations of where the line should be drawn, it 
is best that it be drawn as the discussion area charter says it should... in 
this case, about R, the language. It is pretty explicit that discussion of 
contributed packages is not on-topic... presumably because allowing that can 
easily lead to highly arcane discussions that don't necessarily help people 
understand the R language better.

I think the existence of contributed packages and various development tools is 
hugely beneficial and I depend on many of them... but that doesn't 
automatically give any of them carte blanche to become actual topics of 
discussion here.

Re: [R] tidying up

[Avi Gross via R-help]

Indeed, Jim, the hopeful purpose of interactions here is to help people without 
doing the job for them. As you note, sometimes it is help in getting them to 
formulate what they are trying to do and maybe see the resolution on their own, 
or give enough info that others can troubleshoot.

I have dealt with people on and off forums like this who know very little and 
have done some rudimentary search and found something they hope is helpful and 
then get stuck. Some have no actual interest in learning R or Python or 
anything and see it as a one-time thing. For them, any sustained interaction is 
just frustrating. Others may want a tutor, albeit mahy of us here are not 
willing or able to provide endless hours to volunteer. And some, may be better 
off spending the money to hire someone and I assume there are places they can 
be directed.

Re: [R] Plot by month

[Jim Lemon]

Hi ektaraK,
Here is a step by step way to create an example and get your plot:

# make up a lot of dates
dates<-as.Date("2021-1-1")+sample(0:364,100)
# make up the temperatures
temps<-runif(100,0,40)
# create a data frame
mydf<-data.frame(date=dates,temp=temps)
# create a month variable
mydf$month<-factor(format(mydf$date,"%b"),levels=month.abb)
# calculate mean temperature for months
temp_x_month<-by(mydf$temp,mydf$month,mean)
# create a factor of the months of the year for plotting
months<-factor(month.abb,levels=month.abb)
# plot mean temperature by month
plot(months,temp_x_month,main="Mean temperature by month")

You may only need to apply the last three steps to your data.

Jim

[R] tidying up

[Avi Gross via R-help]

This mailing list seems to steadily get messages that some see as not relevant 
to this forum. In particular, some see it as wrong to bring up some things here 
and keep reminding people of some ground rules.

So I want to know, briefly, if it is reasonable to ask a person with a question 
or problem to reproduce their problem another way. If using RSTUDIO or one of 
many IDE, can they run the code on a naked R interpreter by sourcing the file 
or copying it in or typing it anew, or perhaps using IDLE which comes by 
default with many installations of R? If using a library (which I like so I am 
not really in agreement about the unsuitability) like the tidyverse which is 
free and available to all even if loosely associated with the RSTUDIO folks and 
that can be run on any version of R that I am aware of, then some questions may 
still be fair if they are really about more general R issues as much of the 
rest of the code may be base R and may be the cause of whatever issue is being 
reported. And, some simple requests like pointing out a missing comma, ...

I have stated my thought before and it boils down to the reality that there are 
some things about earlier versions of R that were far from perfect or complete 
and a little healthy competition is not a bad thing and may help base R evolve. 
Not everything in the tidyverse is better and it keeps evolving and deprecating 
older features, but it cannot really be ignored any longer. If you apply for a 
job at some company as something of an R expert, you may well be asked by all 
kinds of people about their programs that use the tidyverse for help or to help 
them solve a problem. You don't have to like it, but if you cannot read it, you 
no longer are really qualified in many places.

Ask yourself if a language like R was created from scratch, what graphics might 
be built into the base distribution? Would you rather have lattice or ggplot or 
perhaps both as well as base R graphics? Would you make many of the built-in 
functions more consistent, so for instance, the data being worked on would be 
the first argument whenever possible? 

One reason there are so many packages is not so much due to the superiority of 
R but because people find it lacks quite a bit. Much of that should not be 
included, of course, if R is meant to be somewhat on the lean side, and yes, 
packages are a deliberate way to extend it when needed. But when people use it 
and think they are programming in R, ...

Hej
Try maybe: dev.off() before plotting.
