Insert tags in header via .Rmd

由 不羁岁月 提交于 2019-12-24 05:40:22
问题 I'm using Rstudio to create Rmd reports, and I'd like to be able to insert meta tags into the <head> when the Rmd is knit into html. From the documentation on knitr options I thought I could set the header option to insert text between the <head> tags like so: ```{r} opts_knit$set(header = "<meta name=\"description\" content=\"this is a description\">") ``` However, nothing seems to be inserted. Am I doing something wrong or is this not possible? 回答1: You use a line in the yaml header that

问题 I knit a Rmd file (to html) with a chunk producing a mp4 movie : ```{r clock, fig.width=7, fig.height=6, fig.show='animate'} par(mar = rep(3, 4)) for (i in seq(pi/2, -4/3 * pi, length = 12)) { plot(0, 0, pch = 20, ann = FALSE, axes = FALSE) arrows(0, 0, cos(i), sin(i)) axis(1, 0, "VI"); axis(2, 0, "IX") axis(3, 0, "XII"); axis(4, 0, "III"); box() } ``` knitr generates the following html code for embedding the mp4 movie : <p><video controls="controls" loop="loop"><source src="figure/clock.mp4"

Issue with creating PDf file with Pander+Knitr: Error when putting table with caption and plot directly next to each other

由 我怕爱的太早我们不能终老 提交于 2019-12-24 05:13:24
问题 I have a reproducible error with pander (+ knitr): When a table with caption and a plot is put directly to each other, I cannot create a PDF File. I use pander 0.5.1, knitr 1.7, R version 3.1.1, Miktex + RStudio on Windows. So the following will produce the error (see also my List of errors and non-errors below): ```{r, echo=FALSE, eval=TRUE} pander(cor(cars), caption="Whatever" ) # or some other captioned table hist(cars$speed) #or some other plot ``` pandoc.exe: Error producing PDF from TeX

Knitr Spin and Rmarkdown Fig.cap (figure caption). Producing double numbering pdf document

由 时光怂恿深爱的人放手 提交于 2019-12-24 04:29:09
问题 I am referring to this Suppress automatic figure numbering in pdf output with r markdown/knitr which I don't think was answered fully. Essentially, I am using knitr::spin and rmarkdown to produce word, pdf and html documents. For word, there appears to be no numbering when one puts in +fig.1, fig.cap = "Figure name" You only get an output Figure name in the caption. To solve that, I used captioner class. figs = captioner("Figure") That works fine for word But I am not faced with rewriting the

问题 When I process my .Rmd file, there is no matplotlib img displayed.

RMarkdown plot inserted into Word with 101% width and height

由 一曲冷凌霜 提交于 2019-12-24 03:16:21
问题 Just like in Title: no matter how fancy or simple a plot I insert into Word from RMarkdown, I get an image with 101% height and width. This is annoying because this makes plots look blurred. Example This short .Rmd file: --- output: word_document --- ```{r, echo=F} plot(1:100) ``` knits to this: Then I right-click on it, select Properties and see it was inserted with 101% of original size (strange language below is polish ;) ) When I reset it to 100%, it looks much nicer: Question How to

Dynamic headers in rmarkdown pdf output

由 人盡茶涼 提交于 2019-12-24 03:12:37
问题 I'm creating reports using what I think is a combination of Rmarkdown/Knitr, YAML, LaTeX and Pandoc (I don't fully understand which parts of my code pertain to what because I'm not well versed in anything except R). I want to know how to add a "dynamic" header, where the contents of the header can be called from variables I read in, for eg., a value from a dataframe I import into the R session. Specifically, I want to add, say, a unique ID# for every report, to be printed on every page of the

Run external R script n times and save outputs in a data frame

由 喜夏-厌秋 提交于 2019-12-24 02:07:02
问题 I have a R script of several hundreds of lines including several randomization functions. Each time I run it I obtain a different result. I am thinking of performing a sensitivity analysis of my model and I wold be interested in running my script hundreds of times and compare the results. After some research, I found out that a combination of lapply and knitr could be a possible solution: result <- c("B:/Documents/result.R") resultsList <- lapply(1:100, function(n) knit(input=result, NULL))
