r-markdown

问题 When I'm inserting long captions and the like in my R chunk header, it'd be nice to be able to split the header across multiple lines. Is there any easy way to do this? E.g.: ```{r, echo=FALSE, warning=FALSE, fig.cap="Here is my really long caption. It'd be nice to split this and other portions across lines"} print(plot(x=runif(100),y=runif(100))) ``` 回答1: No, you cannot insert line breaks in chunk options. From the manual: Chunk options must be written in one line; no line breaks are allowed

问题 I'm really interested in interrupting incremental lists of items created in Rmarkdown with RStudio, to show plots and figures, then retake the list highlighting. This is quite straightforward in Latex, but I couldn't figure out how to achieve the same result using Rmarkdown. Below is some beamer example. --- title: "Sample Document" author: "Author" output: beamer_presentation: fonttheme: structurebold highlight: pygments incremental: yes keep_tex: yes theme: AnnArbor toc: true slide_level: 3

问题 I have the following RMarkdown .Rmd document. When you run the following, the sliderInput is "reactive" and adjust the smoothing appropriately; however, the plot keeps generating in a new separate browser window rather than within the document itself. Any ideas why this is happening or how to fix this behavior? --- title: "Untitled" output: html_document runtime: shiny --- ```{r echo=FALSE} library(dygraphs) sliderInput("span", label = "Select Span", min=0.05, max=1, value=0.5, step=0.05)

问题 I'm trying to use inline R Markdown code to access the first level of a factor. I can get it to work if I use a chunk but not if I do it inline. So while this works: ```{r} as.character(iris$Species[1]) ``` This does not: `r as.character(iris$Species[1])` I could get the inline version to run if I saved the cache and knitted the document twice. I just found this a bit odd because numeric variables behave differently. So, for instance, this works without having to knit it twice `r mean(iris

问题 I am trying to create a table using apa_table() , Papaja, and RMarkdown in RStudio. Whenever I include longtable in the apa_table function, I get the error: ! LaTeX Error: Environment ThreePartTable undefined. Strangely, the error log that's produced includes: (/home/tim/.TinyTeX/texmf-dist/tex/latex/threeparttable/threeparttable.sty Package: threeparttable 2003/06/13 v 3.0 and Package caption Info: threeparttable package is loaded. Note the different capitalization between the error and the

问题 I'm making weighted tables of row proportions using the questionr package. I want to wrap the column names when they are too long. Because I'm making hundreds of tables, the solution needs to work on tables with varying numbers of columns. I also want to avoid setting all columns to a specific width. Ideally, short column names would remain at their normal width while names exceeding the specified maximum length would be wrapped. Here are a bunch of solutions I've tried so far, written as

问题 I am unable to produce a landscape orientation document when using RStudio and Rmarkdown. R is version 3.4.2 RStudio is version 0.98.1103 I cannot change these as they are the latest versions on the cluster which I run my programs on.

问题 I have seen various solutions around which work for pdf and HTML document output. However, none worked for me for word output. When used | as suggested here: Split the title onto multiple lines? simply made the whole title disappear.
