[R] Barplot for data frame
I have a dataframe df <-
df <- data.frame (Revenue = c("100", "300", "500"),
Brand = c("Apple", "HP", "Lenovo")
)
how can i create a vertical barplot that displays brands in x-axis and Revenue
in Y-axis

What have you tried? If you're not currently studying R with an
instructor (who should be contacted with basic questions like this
instead; see the posting guide at [1]), I can recommend a free book by
A. Shipunov [2] to give you the basic R knowledge.

My psychic debugging powers tell me that you're getting an error
complaining about the wrong argument type. If that's the case, you
should either avoid quoting your numbers (i.e. say 100 instead of
"100") or transform the character vector into a vector of numbers using
as.numeric().
Either way, it's best to show your work and your error messages because
the psychic debugging powers don't always work properly.

[R] computer algebra in R
Dear Konrad, I presume that the system can be written as follows, where h0, d0, ga0, kga and kd are given: err1 = h + hd + hga - h0; err2 = d + hd - d0; err3 = ga + hga - ga0; err4 = hga - kga*h*ga; err5 = hd - kd*h*d; All error terms should be zero. Do you need (a) the symbolic solution or (b) is a numeric solution fine? I do not have any experience with yacas or caracas. But see below. ### Case (a) I did write a (very rudimentary) symbolic solver for systems of polynomial equations in pure R. It should be able to solve this one. Please let me know if this is of interest and I will provide further details. ### Case (b) Again, it should be possible to solve, see some examples: https://github.com/discoleo/R/blob/master/Math/Systems.NLE.Tutorial.md https://github.com/discoleo/R/blob/master/Math/Systems.Lambert.R I did solve much more complex ones, for a monster see: https://github.com/discoleo/R/blob/master/Math/Poly.System.S5.Ht.Formulas.Derivation.HS0.R [and the remaining Poly.System.S5.Ht... scripts] I presume that only the real roots are required (it's possible to solve systems with complex roots as well). I can provide further details as well.

[R] Code editor for writing R code
Hi, Currently I use VS-Code to write codes in R. While it is very good, it does not allow me to write Latex expressions in comments, which I am willing to have to write corresponding mathematical expressions as comments in my code files. Does there exist any Code editor for R, that allows me to write Latex in comments? Any information will be appreciated.

Re: [R] Code editor for writing R code
Presumably there's nothing stopping you *writing* LaTeX in comments -- do you want a code editor that will render and display the LaTeX as you write? (Or am I misunderstanding something?)

Re: [R] Code editor for writing R code
Another direction would be to replace your R script (.R file) with a Quarto document (.qmd file). VS-code has good support for Quarto and you could intersperse your Latex with R chunks.

Re: [R] Code editor for writing R code
I believe RMarkdown can use and render latex comments. RStudio/Posix provides ide extensions (e.g. R Notebooks) that seem to do what you want, but I have no experience with them. As Ben suggested, there are likely others, depending on exactly what you want to do. -- Bert On Wed, Nov 29, 2023 at 7:58 AM Christofer Bogaso wrote: > > Hi, > > Currently I use VS-Code to write codes in R.

Re: [R] Code editor for writing R code
Bert, Posit (formerly RStudio) has moved from RMarkdown to Quarto. They still support RMarkdown but major new features will be in Quarto. For new users a better choice would be Quarto. See https://quarto.org/docs/faq/rmarkdown.html Secondly, the OP stated he was using the VS-Code IDE, so there is no reason to point him to the Posit/RStudio IDE for this functionality which VS-Code supports very well (as I noted in my response.)

Re: [R] Code editor for writing R code
Quarto is built on top of RMarkdown when R is used, so RMarkdown isn't going anywhere soon. Don't spread unnecessary FUD. Quarto is well-supported in VSCode, though. And reply to the right branch of the thread... Bert is not in the thread below.

For example, these lines: https://github.com/quarto-dev/quarto-cli/blob/3c9950947871ceafa54de909b15077cd54e27efe/src/resources/rmd/patch.R#L159-L184 have them faking S3 dispatch, but doing it really badly.
