Problems when printing lists inside RJournal template code chunks

由 僤鯓⒐⒋嵵緔 提交于 2019-12-02 22:22:17
问题 I'm using RStudio Version 0.99.896 and trying to compile an article which uses RJournal template (.Rmd). The thing is, whenever I try to compile a simple chunk like ```{r} l = list(a = list(b = c(1,2)), b = c(3,4)) l$a l[[1]]$b ``` i get this awful output (in the .pdf): \begin{Schunk} \begin{Sinput} l = list(a = list(b = c(1,2)), b = c(3,4)) l$a \end{Sinput} \be- gin{Soutput} #> b > [ 1 ] 12 \textbackslash{}end\{Sinput\} \begin{Soutput} > [1] 1 2 \end{Soutput} \textbackslash{}end\{Schunk\}

How can I change paper size when using Knit PDF in RStudio?

由 ╄→гoц情女王★ 提交于 2019-12-02 20:28:58
By default the PDF documents created by the Knit PDF are US Letter size. Instead I would like to create A4 size documents. I have a feeling this should simple to change, either in the RStudio GUI or by adding an option to the metadata at the top of the Rmd file. Unfortunately I can't find any instructions how to do this. Is there a way to specify paper size, preferably within the Rmd file itself? I am still using RStudio version 0.98.953 but can upgrade if it would help. I'd be grateful if someone could point me in the right direction. OK, so I figured it out. In the .Rmd file's header,

Reduce space between code chunks and code output in rmarkdown beamer presentation

由 泪湿孤枕 提交于 2019-12-02 19:20:39
I'm building a presentation using rmarkdown and LaTeX/Beamer. I would like to reduce the spacing between the displayed R-commands and R-output. I believe this is related to the paragraph spacing options in LaTeX/Beamer. Is this something I should do in rmarkdown (chunk options, knit_hooks, or something else?), in the pandoc Yaml header (some pandoc option?), or in the LaTeX beamer template file? I feel like it should be in the LaTeX template file. Below is a working example of a minimal markdown file, and a .tex template file I'm using to control some beamer settings. example.Rmd --- title:

How to show code but hide output in RMarkdown?

由 允我心安 提交于 2019-12-02 19:04:28
I want my html file to show the code, but not the output of this chunk: ```{r echo=True, include=FALSE} fun <- function(b) { for(a in b) {print(a) return(a * a)} } y <- fun(b) ``` When I run the code, i need the print to see the progress (it is quite a long function in reality). But in the knitr file, I use the output in a further chunk, so I do not want to see it in this one (and there's no notion of progress, since the code has already been run). This echo=True, include=FALSE here does not work: the whole thing is hidden (which is the normal behavior of include=FALSE ). What are the

How do I embed images in a list of dataframes?

由 丶灬走出姿态 提交于 2019-12-02 17:44:03
问题 This is a related question to a post I made a few weeks ago here. I am trying to embed QR codes in a new column in a list of dataframes. The QR code will contain the numerical result from the other column and can be scanned into our lab information system. Thus far i am able to generate a dataframe with a column containing QR codes using RMarkdown, but I can't seem to do it when I try to adapt this code to a list of dataframes. Here is an example of what does what I want with a single

How to add new line in Markdown presentation?

由 半世苍凉 提交于 2019-12-02 16:55:31
How to add new line in Markdown presentation? I mean, something like \newline in tex . See the original markdown specification (bold mine): The implication of the “one or more consecutive lines of text” rule is that Markdown supports “hard-wrapped” text paragraphs. This differs significantly from most other text-to-HTML formatters (including Movable Type’s “Convert Line Breaks” option) which translate every line break character in a paragraph into a <br /> tag. When you do want to insert a <br /> break tag using Markdown, you end a line with two or more spaces, then type return. How to add new

How can I use Emacs ESS mode with R markdown?

由 ￣綄美尐妖づ 提交于 2019-12-02 16:43:29
Is there a way to configure Emacs so that it recognizes (and allows execution of) R code chunks within R markdown (.Rmd) files similar to the way it recognizes code chunks in .Rnw (Sweave) or .org (org-mode) files? polymode is being developed which does/will allow you to write markdown with R chunks (for processing with knitr ). Instructions for setting up polymode+rmarkdown are in the README It is not yet done, but is progressing. See also this discussion on the ess-help mailing list ( gmane archive | mailing list archive ) Update: polymode has been released on MELPA, simplifying the
