r-markdown

I am trying to reference a table using the bookdown package. In the documentation the author only shows how to create tables using knitr::kable . ```{r table1} knitr::kable( head(iris, 20), caption = 'Here is a nice table!', booktabs = TRUE ) ``` Table \@ref(tab:table1) is here. Using knitr::kable works just fine. The caption of the table is displayed and I can reference the table. I would like to do the same with a classic hand-made markdown table but obviously the code below fails. What can I do to get a similar result as with the code above? ```{r table2, echo=FALSE, results='asis'} cat('|

I want to demonstrate how to write RMarkdown, where said RMarkdown demonstration is embedded within an RMarkdown document used to create the course material. Within this fenced code block, I don't want knitr to execute the chunk. I want to put something like this into my "top level" Rmarkdown document, and have everything that's between the outer fences be printed verbatim in fixed width in the output HTML document, rather than having knitr evaluate the inner embedded R code chunk and inline code. ``` --- title: "RMarkdown teaching demo" author: "whoever" --- # Major heading Here's some text

I get an error message when running the code below which is expected - I would like this to be ran and displayed in the pdf, however the error is returned in r and the code doesn't run. {r, warning=TRUE} library(survey) debug(withReplicates.svyrep.design) I have tried warning=TRUE but this doesn't work. How can I get the error displayed in the document? Add error=TRUE to the chunk options. That will result in the script running to completion with the error appearing in the output. 来源： https://stackoverflow.com/questions/34137797/rmarkdown-run-code-and-display-errors-in-document

Is it possible to include code from an external R script in an .Rmd and simultaneously run the code, display the code, and display its results in the output .HTML file? For example, if I have x <- 1 y <- 3 z <- x + y z in external.R . In the output document I want to see the code above along with the result of z , i.e. 4. Essentially, I want the equivalent of what would happen if I copy/pasted what's above in an R chunk. So I want ```{r} some.library::some.function("external.R") ``` to be the equivalent of ```{r} x <- 1 y <- 3 z <- x + y z ``` In the output HTML file. I've tried things like

In my documents in r parts I use long codes like: ```{r} output <- "very long query for example url to some website............................................." output ``` Is there any way not to make R wrap the code automatically, let's say after 60 characters? I tried tidy=TRUE, tidy.opts=list(width.cutoff=60) option but it doesn't work. And I want the same with output, because the output of my query is some text. I want to display the whole content in many lines, not just the begining in one line. How can I do it? Things have changed since 2015, but FWIW given that you are now using

I'm writing in R Markdown and have a contingency table that is quite wide. I am converting the R markdown document to a PDF using pandoc. Is it possible to rotate or shrink the table? Ideally this would be done without having to switch to LaTeX formatting. My Attempts: I've been abusing the figure options in knitr to attempt this, but whether I use kable or xtable, I haven't had any luck. Some permutations I have tried include: ```{r out.extra='angle=90', results='asis'} library(knitr) kable(iris[1:5,]) ``` ``{r size='footnotesize', results='asis'} library(knitr) kable(iris[1:5,]) ``` ```{r
