knitr

问题 Are there minimal, or even larger, working examples of using SCons and knitr to generate reports from .Rmd files? knit ing an cleaning_session.Rmd file from the command line ( bash shell) to derive an .html file, may be done via: Rscript -e "library(knitr); knit('cleaning_session.Rmd')". In this example, Rscript and instructions are fed to a Make file: RMDFILE=test html : Rscript -e "require(knitr); require(markdown); knit('$(RMDFILE).rmd', '$(RMDFILE).md'); markdownToHTML('$(RMDFILE).md', '$

问题 I am writing a report using knitr in RStudio. Also using the psych package for factor analysis: ```{r, results='asis'} library(psych) data(Thurstone) fa.Thurstone<-fa(Thurstone) fa2latex(fa.Thurstone) ``` When I run this code chunk it causes an error: ! LaTeX Error: Unknown float option `d'. See the LaTeX manual or LaTeX Companion for explanation. Type H <return> for immediate help. ... l.124 \begin{scriptsize} \begin{table}[htdp] pandoc: Error producing PDF from TeX source Error: pandoc

问题 I am using RStudio version 0.98.501, R version 3.0.2 on Windows 7. I have following code written in a .Rmd file: --- title: "Sample Document" output: html_document: toc: true theme: united --- Title ======================================================== This is an R Markdown document. Markdown is a simple formatting syntax for authoring web pages (click the **Help** toolbar button for more details on using R Markdown). When you click the **Knit HTML** button a web page will be generated

问题 New to markdown and knit, so... In RStudio, this markdown code does well ## 'r': razão entre opções ```{r} round(apply(rst0[,c('rstQ','rstV','rstMkt','rstMkt2','rstAntiMkt')],2,mean),3) ``` rstQ rstV rstMkt rstMkt2 rstAntiMkt 81.408 111.098 0.012 0.007 0.005 But when I click knit button, I get error: Line 20 Error in apply(rst0[,c('rstQ','rstV','rstMkt','rstMkt2','rstAntiMkt')], : object 'rst0' not found Calls: <Anonimous> ... withCallingHandlers -> withVisible -> eval -> eval -> apply But

问题 I'm having difficulty using psych::fa2latex in the context of an RMarkdown document to produce a factor analysis result. If you just run the first bit of code in an RMarkdown document in RStudio (1.0.153), you get an error message : " LaTeX Error: \caption outside float” and the document does not compile. Thanks for any help. ##Place In RMarkdown Document, save and compile. --- title: "Test" author: "Simon Kiss" date: '2018-01-09' output: pdf_document --- ```{r setup, include=FALSE} knitr:

问题 I pretty much copied word-for-word the example from this site on how to create multiple PDFs in knitr from one for-loop: http://www.reed.edu/data-at-reed/software/R/markdown_multiple_reports.html When I try calling knitr::kable(cars) or kable(cars) the output of each PDF appears as one long column instead of an actual table, as shown in the photo. Any idea what causes this? Here's the .R and the .Rmd code called in each iteration of the loop: .R library(knitr) library(markdown) library

问题 I can't seem to figure this out.. in R Studio with an rhtml file, I want this: <!--begin.rcode test <-1 end.rcode--> To look like this in the html output: 1 But it currently looks like this: ## [1] 1 Basically looking to build an html page around this.. So all the extra divs and code generated by the knitr notation need to be excluded. racking my head on this one. 回答1: echo controls the display of code results controls the output of the code evaluations message controls the messages warning

问题 Hi I have a simple shiny app from which i wish to download a pdf table after importing a csv file into it. I suspect that i use the parameters incorrectly as i take : Error : 'file' must be a character string or connection #ui.r library(shiny) library(rmarkdown) fluidPage(sidebarLayout( sidebarPanel( fileInput("file1", "Input CSV-File"), downloadButton( outputId = "downloader", label = "Download PDF" ) ), mainPanel(tableOutput("table")) )) #server.r function(input, output) { thedata <-

问题 Currently kableExtra 0.5.1 only supports Put a few rows of a table into one category . I wonder if there is any tweak to Put a few rows of a table into many categories programmatically like group_rows(kable_input = x, group_label = c("Group 1", "Group 2"), start_row = c(1, 5), end_row = c(2, 6)) . Thanks library(knitr) library(kableExtra) x <- knitr::kable(head(mtcars, 10), "latex") kableExtra::group_rows(kable_input = x, group_label = c("Group 1", "Group 2"), start_row = c(1, 5), end_row = c

问题 Since our update to R2.15.1, the tables in my lyx documents that result from calls to the latex function (package Hmisc) open in an external xdvik-window instead of being inserted in the pdf-document that I am compiling. On the contrary, the tables produced with xtable and the graphs produced with ggplot do appear where they belong in the document. The chunk header for the latex call is <<Specs,tidy=F,results='asis',eval=F>>= and the chunk is then referred to multiple times with e.g. <
