问题 Is there a way to combine animation package and r markdown? I want to generate animation which i want to include and describe in html file generated from r markdown. Of course I can embed code from saveHTML or saveGIF file in already generated r markdown file, but i want to automate this process. I'm working on Windows, R 15.1 and the last RStudio. 回答1: Here is the clock example from the knitr graphics manual (see comment on your question) in markdown: ```{r clock, fig.width=7, fig.height=6,

问题 How can I get captions on my table floats in pdf_document generated by rmarkdown? Using output: pdf_document: fig_caption: true and ```{r, fig.cap='a caption'} myplot ``` Generates a floating figure with myplot and the caption specified. How do I achieve the same thing with tables generated by xtable? ```{r, results='asis', fig.cap='table caption'} print(xtable(table), comment = FALSE) ``` I have tried using floating.environment = 'figure' in print.xtable, but to no avail. 回答1: Or similarly,

问题 I know it's a fairly old problem, and it has been discussed before, but I can't get it work as expected. I have a markdown document, and I would like to use knitr and pander to produce a .docx report with a consistent numeric format with two decimals, such as 0.12, 3.60, 14.00, or 163.21 for both inline and chunk outputs. I have read this thread How to avoid using round() in every \Sexpr{}? where it was suggested that pander can do that automatically. However, it does not seem to work for me.

问题 I'm writing a report in R with knitr. I'm using xtable() to generate tables in the report. One of my tables includes both negative and positive numbers. I'd like to change the color of negative numbers into red. How can I do that? Obviously, one easy solution is to change the latex code that xtable generates BUT note that I have an auto-report that numbers can change with new datasets and I don't want to manually set the colors. Here is a simple code: \documentclass{article} \begin{document}

问题 I'm using rmarkdown to produce a word (.docx) report. I would like to change the header of the toc. This seems possible as pandoc_args can be passed as options in the yaml header in the case of a doc file (1). But I'm not doing it right. Could anyone provide a working example ? (1) pandoc.args is included in the rmarkdown possible options and in the pandoc manual, there is a toc-title option --- title: "yaml header" author: "cedric" output: word_document: toc: true pandoc_args: toc-title=

问题 I have an RMarkdown document outputting to HTML of the same form as the below example. What do I add where to apply unique CSS ids or classes to each plot output? --- title: "RMarkdown" author: "Me" date: "Friday, March 27, 2015" output: html_document: theme: null css: style.css --- ```{r plot1, echo=FALSE, warning=FALSE, message=FALSE} library(ggplot2) x <- ggplot(some_r_code) print(x) ``` ```{r plot2, echo=FALSE, warning=FALSE, message=FALSE} y <- ggplot(some_more_r_code) print(y) ``` I've

问题 This question already has answers here : Is there an R Markdown equivalent to \Sexpr{} in Sweave? (2 answers) Closed last year . In R markdown (knitr package), can I access a variable within the body of the document that was calculated in a code chunk? 回答1: Yes. You can simply call any previously evaluated variable inline. e.g. If you had previously created a data.frame in a chunk with df <- data.frame(x=1:10) `r max(df$x)` Should produce 10 回答2: I would like to add that this is not the case

问题 I have seen answers to creating side by side xtables in RMarkdown-HTML knitr, R Markdown, and xtable: xtable tables within HTML table and how to create side by side xtables in Sweave directly R: Print two tables with xtable () But how about side by side xtables in Rmarkdown/Pandoc? In my *Rmd file I have ```{r , results='asis', message=FALSE, echo=FALSE} female.bmi <- lm(bmi ~ AGEGROUP + RACE + GEO_SPA + FPL_FIN + as.factor(year), data=lach[lach$GENDER=='Female',] ) xtable(female.bmi, comment

问题 I'm aware that R markdown can produce superscripts: text^superscript But is it possible to produce proper subscripts? Or is the only way to do so to cheat and use LaTeX math mode: $\sf{text_{subscript}}$ The intended final output is HTML. 回答1: Since you mention Pandoc in your comments, maybe it's not cheating to depend on Pandoc's extensions for subscript and superscript . From here, we can create a minimal example Rmd file: Testing Subscript and Superscript ==================================
