问题 I'm sure it's a simple solution but Ive been searching all day trying to solve this. All I want to do is split an xtable caption over 2 lines. I've tried \n and caption.width to no avail. \documentclass{article} \usepackage{caption} \begin{document} <<makedata,echo=TRUE,results='asis'>>= df <- matrix(round(rnorm(9, 20, 10)), 3, 3) colnames(df) <- c("Column1","Column2","Column3") require(xtable) print (xtable(df, caption="Title1\nTitle2"),caption.placement="top") @ \end{document} 回答1: I think

问题 I've long used apsrtable to quickly create model comparison tables, but I find it somewhat unattractive and clunky, so my dissertation tables were hand-coded tables with \Sexpr expressions. I was excited to find stargazer , but disappointed that some models I use aren't supported. With apsrtable you can fairly easily extend a model by updating the apsrtableSummary and ModelInfo methods (as in this question/answer). I've been looking (but haven't found) for a similar method to extend stargazer

问题 Rstudio will not knit. I have been using it for a few weeks in a course. When I try to knit it executes until it comes to some code and it stops. The code is ggplot(data = gss, aes(x = year, fill = degree)) + geom_bar() The message is could not find function "ggplot" This happens with other functions as well. With the code commented out is will run and produce an HTML file. I have reinstalled R and Rstudio twice. I have had difficulty with my AV software (Bitdefender) blocking the install of

问题 Rmarkdown output to word creates one table instead of two The code below is expected to create two independent tables when I knit a Word document using Rmarkdown in Rstudio, but instead it creates one combined table. Code expected to create a word document with two tables: --- title: "Untitled" output: word_document --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = FALSE) ``` ## R Markdown ```{r} knitr::kable(head(iris)) ``` ```{r} knitr::kable(head(iris)) ``` But it only creates

问题 Is is possible to hide some comments in code when kniting using knitr / R markdown? Example: --- title: "SOSO" author: "SO" date: '2017-06-06' output: pdf_document --- ```{r} # Generate some data rnorm(2) ## But keep this comment ``` When kniting I would like the first comment to disapear, but keep the second one somehow. 回答1: Here is a quick example of modifying the hook to change knitr behavior. --- title: "SOSO" author: "SO" date: 2017-06-06 output: pdf_document --- ```{r setup-hook, echo

问题 My aim is write a document in markdown ( rmarkdown , more specifically), that can be compiled both to a regular PDF (or other) file and a beamer presentation at the same time, from the same source. (Using knitr .) Scenario: the document includes, in addition to the regular text, one sentence summaries for each paragraph and these should go to the presentation as the bullet points. I know that I can compile a document to several different output formats at the same time with knitr , but the
