knitr: child document in different directory

由 旧城冷巷雨未停 提交于 2019-12-06 10:06:26
问题 I can use the following code for child document if it is in the same directory. <<child-demo, child=knitr-input-child.Rnw, eval=TRUE>>= @ I wonder how to use child document if it is not in the same directory of master document. Thanks in advance for your help and time. 回答1: This can be considered as a bug. Now I have fixed it on GitHub. Note, however, you need to setwd() to the directory of your master document before using knit() , otherwise knit() may not be able to find a child inputdir

trouble finding file source in .rmd chunk when knitting .rmd from master .R file

问题 Let's say I have a project directory called testknit (and I do, see github for MRE), and inside this I have several subdirectories, including scripts where I keep .R and .rmd files. In RStudio, I create a project and select this testknit directory so that when I open the project, the working directory is mypath/testknit . Inside testknit/scripts I have a master.R file. If I want to source a file called testsource1.R , which is also in testknit/scripts , I can run source("scripts/testsource1.R

Automate RStudio processed RMarkdown?

由 筅森魡賤 提交于 2019-12-06 08:19:03
问题 I have an RMarkdown file that I use to generate a nice HTML report. The problem is, I want to be able to automate it so that it can run on a headless server. As such there will be nobody there to start Rstudio and press the 'knithtml' button and it seems that Rstudio is doing a LOT of additional magic like having it's own version of pandoc, running all the necessary commands, applying css styles etc. How can I take this report and generate the same thing Rstudio is generating when I press the

How can I insert an image from internet to the pdf file produced by R bookdown in a smart way?

由 左心房为你撑大大i 提交于 2019-12-06 07:34:05
问题 As far as I know, inserting an image from internet to LaTeX is not possible. You have to download the image first, and then include it locally. With R bookdown, I do it like this: download.file('https://bookdown.org/yihui/bookdown/images/cover.jpg','cover.jpg', mode = 'wb') knitr::include_graphics('cover.jpg') It works very well for both the gitbook and pdf outputs. But I do not think it is smart. It is necessary for pdf to download the file first, but unnecessary for gitbook output. The

How to use a “R-generated” plot as a semi-transparent background in an HTML5 slide made by knitr?

由 风流意气都作罢 提交于 2019-12-06 07:12:16
问题 I want to add a plot to my first page of the (HTML5) slide. Can I achieve this in a dynamically way? Say, the background image will be generated by R code, rather than insert a semi-transparent PNG image. Thank you. Update : What I want is 回答1: You can use the chunk option dev.args to achieve this. You will need to size the image correctly to fit your slide. ```{r dev.args = list(bg = 'transparent')} plot(1:10, 1:10) ``` This chunk will generate a transparent png. Please read the

How can knitr keep warning messages inside the box?

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-12-06 05:50:17
I'm writing a tutorial using knitr and I want to show some of the warnings and errors that students might encounter. While I'm capable of nicely displaying the code chunks within the box using the tidy=TRUE option, I don't understand how to handle the display of warnings and errors. For example, if I have the following code: \documentclass{article} \begin{document} <<setupOp, include=FALSE>>= opts_chunk$set(tidy=TRUE, tidy.opts=list(blank=FALSE, width.cutoff=20)) @ <<ErrorTest>>= warning(paste("A suuuuuuuuuuuuuuuuuper", "loooooooooooong waaaaaaaaaaaaarning")) @ \end{document} The warning code

opts_current: how does it work in knitr?

由 故事扮演 提交于 2019-12-06 05:35:54
I am trying to set up different figure size in different chunks. I first define a global settings using: opts_chunk$set(fig.width=7, fig.height=7) Then, for the specific chunks, I use: opts_current$set(fig.width=7, fig.height=14) But the later is always neglected. So, how does opts_current really work? For specific code chunks, put the chunk options in the chunk header, e.g. ```{r fig.width=7, fig.height=14} These are called local chunk options, which will override global chunk options (temporarily for this specific chunk). 来源： https://stackoverflow.com/questions/25776547/opts-current-how-does
