knitr

I am trying to use RMarkdown (Knit) for the first time to produce pdf. The default file (File > New File > R Markdown) works well, it shows the generated pdf when compiled. For example, the following code runs, ```{r cars} summary(cars) ``` However, if I just change cars with "myData," it does not compile and shows, Error in object[[i]] : object of type 'closure' is not subsettable Calls: <Anonymous> ... withVisible -> eval -> eval -> summary -> summary.default Execution halted I have "myData" loaded in the global-environment and can do other operations in original R script. Can someone please

I'm searching and trying to add a image as watermark to rmarkdown pdf, I'm using the render function to generate the PDFs, and saw the \usepackage{draftwatermark} and this question: Watermark in rmarkdown But they don't help me in adding a image as watermark. --EDIT-- I achieved what I wanted putting this to the header of .Rmd: header-includes: - \usepackage{eso-pic,graphicx,transparent} And placing this in the start of file (before the rest of .Rmd): \AddToShipoutPictureFG{ \put(0,0){% \parbox[b][\paperheight]{\paperwidth}{% \centering {\transparent{0.3} \includegraphics[width=\paperwidth

I would like to be able to use knitr to produce a structured PDF file. I did not see anything unless the input file is Sweave format. This question may be too vague but I really like to know right from knitr , is it possible to create a structured PDF output file without using any Sweave or LaTeX ? RUser Try using command knit2pdf if you haven't already. 来源： https://stackoverflow.com/questions/14586177/knitr-to-produce-pdf-output-file

I am trying to include a .png file in a file that I am rendering using bookdown. knitr::include_graphics() should be the way to go. The code: ```{r fig1, fig.cap='My Caption', echo=FALSE, message=FALSE, warning=FALSE} knitr::include_graphics("./Figures/My Figure.png") ``` In the .Rmd file, I can run my r block, and it renders the image below. So, the path should be correct. However, when I knit the chapter, or render the entire book, the figure is not rendered. Could it be that some of my other options are overriding the figure? Below are my YAML header of the index.Rmd file, and the code in

I have sweave file like this: test.rnw \documentclass[letter,10pt]{article} \usepackage{amsmath} \usepackage{amscd} \usepackage{ifthen} \usepackage[utf8]{inputenc} \usepackage{hyperref} \usepackage[top=1.0in, bottom=1.0in, left=0.75in, right=0.75in]{geometry} \begin{document} \title{Top areas of focus for \\ This is a test} \author{ test } \maketitle \pagebreak \tableofcontents \pagebreak \section{Introduction} this is a test document \end{document} I am trying to manually run knitr agaist it and produce a pdf file like this: knit2pdf("test.rnw", "test.pdf", compiler="texi2pdf") I am getting

I'm basing my rmarkdown -Jekyll-Blog off of Yihui's fantastic boilerplate for using servr::jekyll() , which in turn wraps knitr . Because I want to use citations (via pandoc-citeproc , wrapped by rmarkdown ) I need to use rmarkdown::render , not knitr to, well, render the *.md s. As per the servr manual, I understand that rmdv2() should do the job, which essentially wraps/modifies jekyll() : The functions rmdv1() and rmdv2() are similar to jekyll(), and the only difference is the way to compile R Markdown documents: rmdv1() uses the markdown package (a.k.a R Markdown v1) via knit2html(), and
