knitr

I am using a for loop to create multiple big figures across multiple pages in one chunk with knitr and rmarkdown. It works fine for word and html outputs, but has one problem in pdf output. This is a minimal RMarkdown example to reproduce my problem. --- title: "Knitr test" date: "6 April 2015" output: pdf_document --- ```{r, echo=FALSE, fig.width=6.5,fig.height=10} library(ggplot2) for (i in seq(1, 4)){ p <- ggplot(cars, aes(speed, dist)) + geom_point() print(p) } ``` The generated pdf file looks like this. Two figures are printed in the page. If I change the fig.height, add a few section in

Standard R output looks like this > 3 [1] 3 To remove the prefix 1 you can use > cat(3) 3 Is there a way to remove this globally? Or do you have to wrap cat() around everything? Further to that, I'm using this within knitr, so if there isn't an R global setting, there may be a knitr wide setting, I did look, but couldn't see one. Edit: It was asked why one would want this, something like if you wanted to structure a report like the below. The [1] is just not needed and means nothing to none R users (aka, the audience). Additional Info: In knitr you can use \Sexpr{} or r ... to evaluate

stargazer automatically centres values within tables. How can I left align the columns? Put this code in an .Rnw file and use knitr to convert to .tex: <<load, echo=FALSE, warning=FALSE, message=FALSE>>= opts_chunk$set(eval=TRUE, echo=FALSE, warning=FALSE, message=FALSE, dpi=300) @ \documentclass[a4paper,11pt]{article} \usepackage{lipsum} % Required to insert dummy text \begin{document} \title{} \author{} \date{\today} \maketitle \section{Header} Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam,

I am trying to use DT::datatable to output a nicely formatted, interactive table in R. ...only problem is that I want a heroku job to knit the document for me, and I've learned that RStudio and rmarkdown::render() use pandoc under the hood -- but pandoc doesn't ship in the stripped down R Buildpack for heroku. Is there any way to get the old markdown engine ( knitr:knit2html or markdown:markdownToHTML ) to pass the javascript that powers datatable through? Or to be more precise, to generate the sample table below without using pandoc? Here is a minimal example: testing.Rmd --- title: "testing"

I want to export a .Rmd file primarily as a latex pdf. This is the code that I'm currently using ```{r ,fig.cap="caption",fig.env='figure', fig.width=10, fig.height=10,echo=FALSE, results='asis', warning=FALSE, strip.white=TRUE} library(png) library(grid) img <- readPNG("filepath/overview.png") grid.raster(img) ``` As you can see, I'm already using strip.white=TRUE & fig.env='figure' but they don't seem to work. The .PNG file hasn't got any (white) spacing above or below the image. I know I can use latex directly and achieve what I want, but I want to able to reproduce this in Word if needed.
