问题 First, the package kableExtra indeed produces awesome table. I just have an additional request : When running this example ( from the manual) iris[1:10, ] %>% select(-Species) %>% mutate_if(is.numeric, function(x) { cell_spec(x, "latex", bold = T, color = spec_color(x, end = 0.9), font_size = spec_font_size(x)) }) %>% kable("latex", escape = F, booktabs = T, linesep = "", align = "c") The cells are formated in each column. (1) How to adjust them to the entire table ? (2) Or to a user defined

问题 I've been using rmarkdown and knitr to create html output. Quite suddenly, the {.tabset} function seems to have stopped working when knitting, and documents render as they would without this option. Here is a simple example that does not work as it should on my system. --- title: "Plot Tabs" output: html_document --- ```{r setup, include=FALSE} knitr::opts_chunk$set(echo = FALSE) ``` ## Title {.tabset .tabset-fade .tabset-pills} ### tab 1 ```{r} plot(cars) ``` ### tab 2 ```{r} plot(pressure)

问题 When I knit my R Markdown document to pdf, some of my pages have this Error ## Warning in grid.Call(C_textBounds, as.graphicsAnnot(x$label), x$x, x$y, : See screenshot below. What could be the problem? I am not using any new fonts and the laptop is a mac. 回答1: You are using an en-dash; for some reason there are specific bugs for this character. See R -e 'library(ggplot2); qplot(Sepal.Length, Petal.Length, data=iris, main="Big–booté")' open Rplots.pdf As you can see, the “é” characters are

问题 I am working in R Markdown, knitting to PDF. I thought the following code should create a table with a local image, but it is not working. Any help would be greatly appreciated! column1 <- c("1", "2", "3") column2 <- c("a", "b", "c") column3 <- c("x", "y", "z") dat <- data.frame(column1, column2, column3) dat$column1[1] <- "{ width=25px }" print(kable(dat)) 回答1: --- title: "pic in column" author: "test" date: "2014/08/03" output: html_document --- ```{r results='asis'}

问题 I am using Knitr and rmarkdown. I have suppressed warnings in the .pdf output and then typically the warnings are listed in the rmarkdown console. However, in the case of one specific report, instead of getting the warnings listed in the rmarkdown console, I get this message: There were 15 warnings (use warnings() to see them). Where do I write this warnings() code to see the list of warnings? I have tried adding warnings() at the bottom of my rmarkdown document but the output is: NULL. 回答1:

问题 I am trying to render the following table in a RMD file: \begin{table}[] \centering \caption{My caption} \label{my-label} \begin{tabular}{|l|} \hline \\ \hline \end{tabular} \end{table} So far no success. Is there any fundamental reason why rmarkdown cannot compile LaTeX enviroments (other than equations) to HTML? 回答1: In a markdown document, the expected input markup language is (r)markdown. You should not expect pandoc to automatically recognize arbitrarily mixed markup languages. LaTeX
