rnotebook

问题 My code chunk output in Rnotebook is not appearing (as if not being run) when I try to view data frame results. I have to pass it through the pander() function to see the output print out. Is this something to do with knitr? I mention this because I set the options at the beginning to the following: ```{r setup, include = FALSE} knitr::opts_chunk$set(echo = TRUE, eval = TRUE) ``` I have tried setting the options directly in the chunk but get the same unwanted result. Is there a setting I am

问题 Very simple question: I love writing R notebooks/markdowns, and with something like highlight: tango I can give background color to codes when I knit my notebook to pdfs. However, I don't know how to give colored backgrounds or colored fonts to printed outputs in R. For example, suppose I have the following chunk. ```{r, echo = FALSE} writeLines("Help") ``` I'd like to see the word Help to be highlighted, say in red font with gray background. How can I achieve this? Many thanks in advance.

问题 I am creating R notebooks that contain equations. I am using RStudio 1.2.5033 on Windows 10, R 3.5.1, and rmarkdown 2.1. When my R notebooks are rendered as HTML, MathJax (v2.7.2) uses the "HTML-CSS" output processor to render the equations. But I think that the output from the "CommonHTML" output processor looks better. So I want to include a directive, in my R notebooks, that forces MathJax to use the CommonHTML output processor. How may I do this? If I were rendering an ordinary R Markdown

问题 It is sometimes desirable to create an R notebook that isn't self-contained. For example, one may want to load Mathjax from a local file of one's choosing, and to do so, self_contained must be FALSE. But I find that, by default, even the simplest R notebooks don't render properly when the YAML header includes self_contained: FALSE . Here is a minimal example: --- title: "Notebook, not self-contained" output: html_notebook: self_contained: false --- Hello. When this file is rendered with the

问题 Running Ubuntu 17.10, and running R Notebook on RStudio through Anaconda. When I try to run the simple example from the rbokeh website in a R Notebook : p <- figure() %>% ly_points(Sepal.Length, Sepal.Width, data = iris, color = Species, glyph = Species, hover = list(Sepal.Length, Sepal.Width)) I get the following warning message: In structure(x, class = unique(c("AsIs", oldClass(x)))) : Calling 'structure(NULL, *)' is deprecated, as NULL cannot have attributes. Consider 'structure(list(), *)

问题 I am building a custom formatted notebook using some css and html. As recommended this is implemented using a wrapper function around an rmarkdown function. quarterly_report <- function(toc = TRUE) { # get the locations of resource files located within the package css <- system.file("reports/styles.css", package = "mypackage") header <- system.file("reports/quarterly/header.html", package = "mypackage") # call the base html_document function rmarkdown::html_notebook(toc = toc, fig_width = 6.5

问题 I'm using an R Notebook and I'd like my plots to automatically save to disk when the code is run, as well as display inline. knitr: include figures in report *and* output figures to separate files addresses this for R Markdown but the solution given doesn't work for an R Notebook. Is there a similar option for R Notebooks? 回答1: Try setting the knitr fig.path option: knitr::opts_chunk$set(fig.path = "path/to/figures/") Where path/to/figures/ is the path to a subdirectory where your figures

问题 I know how to change the dpi of a plot when knitting a rmarkdown notebook to html. However is there a way to change the dpi of a plot generated in a rmarkdown notebook without having to knit the document, id est the plot is shown as inline output between two code chunks while working on the notebook? 来源： https://stackoverflow.com/questions/53884985/how-can-i-change-dpi-inline-code-output-in-notebook-rmarkdown
