问题 Trying to knit to pdf from RStudio using a custom mystyles.sty file. This used to work fine but now that I have upgraded to RStudio 1.044 I get an error.

问题 I am working on creating a dynamic rmarkdown document. The end result should create a tab for each 'classification' in the data. Each tab should have a datatable, from the DT package, with the data printed to it. Below is the code I have been using: --- output: html_document --- # Setup{.tabset} ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = FALSE) library(knitr) library(DT) ``` ```{r data.setup} set.seed = 1242 rows = 64 data.1 = runif(rows, 25, 75) data.2 = runif(rows, .01, 1)

问题 I am using bookdown to generate slides for a workshop. I use the 'big' letter option in the menu for display as slides. However then the chapter title font size is too large. Where/how can I modify that one? Thanks, Paul 回答1: you can control this with .css as yihui suggests in the top level of your bookdown project there is a file called style.css open it and paste in: .book .book-body .page-wrapper .page-inner section.normal h1{font-size:1em} this will increase the size of your top level

问题 Thanks to jaySf I was able to create a pdf file containing beautiful tables with footnotes showing formulas and symbols with R Markdown, Latex, knitr and kableExtra (below his example): --- title: "Untitled" output: pdf_document --- ```{r tab} library(knitr) library(kableExtra) df <- data.frame(v1=rnorm(6), v2=runif(6), v3=rbinom(6, 1, .33), row.names=LETTERS[1:6]) kable(df, "latex", align="c", booktabs=TRUE) %>% footnote(general=c("$a^2+b^2=c^2,$", "$\\\\sigma^2=\\\\frac{1}{n-1}\\\\sum_{i=1}

问题 Is there any way to insert a fully formatted citation in RMarkdown in-text. For example, something like this: You enter the citation key @watson1953 and it renders (as a latex PDF) as Watson, J. D., & Crick, F. H. C. (1953). Molecular structure of nucleic acids: A structure for deoxyribose nucleic acid. Nature, 171(737-738), 3-12. But it does it in exact location of the citation key. The bibliography at the end of the document should also be suppressed. Is there any way to do this? I couldn't

问题 I get an error message when running the code below which is expected - I would like this to be ran and displayed in the pdf, however the error is returned in r and the code doesn't run. {r, warning=TRUE} library(survey) debug(withReplicates.svyrep.design) I have tried warning=TRUE but this doesn't work. How can I get the error displayed in the document? 回答1: Add error=TRUE to the chunk options. That will result in the script running to completion with the error appearing in the output. 来源：

问题 Is it possible to include code from an external R script in an .Rmd and simultaneously run the code, display the code, and display its results in the output .HTML file? For example, if I have x <- 1 y <- 3 z <- x + y z in external.R . In the output document I want to see the code above along with the result of z , i.e. 4. Essentially, I want the equivalent of what would happen if I copy/pasted what's above in an R chunk. So I want ```{r} some.library::some.function("external.R") ``` to be the

问题 I have a shiny application that read a csv file and clean the data and add few columns, ... (I used this example to create the app). At the end the application save the cleaned data ( output.csv ) in the log folder within the application folder. I also design a Rmd file which is in the shiny application folder. The Rmd file uses the output file ( log/output.csv ). I would like to call the Rmd file to show the report after saving the ( output.csv ), How can I do it? 回答1: I found the solution

问题 I've created a plotly chart in R and then save the plot via htmlwidget so the plot can called in slidify. I played with width and height , in both layout argument and index.Rmd to fit the plot on a slidify slide but the final result always cut the bottom portion of the chart when some texts are added together. How can I truly adjust the size of the plotly chart in slidify? The code in R script ## first slide date <- seq(from = as.POSIXct("2015/4/1"), to = as.POSIXct("2015/10/1"), by = "month"
