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 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 documentation ? png to get a list of arguments you can pass. Here is one useful piece onf info from the docs. png

I refer to the code example at http://shiny.rstudio.com/gallery/including-html-text-and-markdown-files.html . In my case I would like to include and R markdown file rather than a markdown. The following is my code for ui.R library(markdown) shinyUI(fluidPage( titlePanel("Tourist expenditure for the year 2012 in Malta"), fluidRow( column(2, checkboxGroupInput("id1", "Analyse by", c("Sex" = "1", "Age Group" = "2") )), column(6, h4('You entered'), verbatimTextOutput("oid1") ), column(4, includeMarkdown("intro.Rmd") ) ) )) My problem is that intro.Rmd is not compiling when embedded in shinyUI but

I am trying to convert a .Rmd file to .md (output: md_document), but the title does not show up on the rendered file. The title does show up when I try to render the same file as an .html file (output: html_document). Title shows up on rendered document: --- title: "Test" output: html_document --- ```{r} head(cars) ``` Title does not show up on rendered document: --- title: "Test" output: md_document --- ```{r} head(cars) ``` rmarkdown::render(my_file) Any ideas why? I am using RStudio 0.98.1091 and R 3.1.2 on a Mac 10.9.5. The code in between -- gets interpreted, as my references are rendered

When I try to knit a RMarkdown document with ggvis plots to Word, I get the following message from Rstudio. Error: Functions that produce HTML output found in document targeting docx output. Please change the output type of this document to HTML. Execution halted Does there exist an elegant solution (without too much effort) to make this possible, perhaps using export_png and vg2png ? Here is an example: ```{r setup, include=FALSE} library(dplyr) library(ggvis) ``` The following table looks fine... As long as I don't include this plot below ```{r, echo=FALSE, include=FALSE} p <- pressure %>%

Is it possible to omit interactions in stargazer using the omit option? Normally I would write the variable name into the omit=c('varname') but in the case of an interaction I do not know what to write. Any hints on that? How do you solve this problem in other packages like xtable ? \documentclass{article} \begin{document} %Load dataset and run regression << lm, echo=FALSE >>= load('dataset.RData') library(stargazer) lm1 <- lm(y~ x + factor(v)*z ,data=dataset) @ << table_texstyle, echo=FALSE, comment=NA, results='asis' >>= stargazer(lm1 ,omit=c('???'), omit.labels=c('Omitted interactions'),

I've a set of tables that I'm generating with use of the code similar to the snippet below: ```{r tables, echo=TRUE, eval=TRUE} require(reshape2); require(pander) data("mtcars") data("AirPassengers") dta_lst <- list(mtcars, AirPassengers) for (i in 1:length(dta_lst)) { pander(melt(head(dta_lst[[i]], n = 2), varnames = c("Something"), value.name = "Something else"), caption = paste("Some table for: ", class(dta_lst[[i]]))) } ``` When I run the code it produces the desired output (naturally, the provided example makes little sense, in my proper data I melt the data in sensible manner): ---------
