问题 I am trying to create a page with side-by-side tables. I used other SO answers to do this for a simple table ```{r start-block, include=F,echo=F} library(dplyr) library(knitr) library(kableExtra) ``` ```{r sample, echo=FALSE, results='asis'} t1 <- kable(head(mtcars)[1:3], format = "latex", booktabs = TRUE) %>% kable_styling(latex_options = c("striped"), font_size=5) t2 <- kable(head(mtcars)[4:6], format = "latex", booktabs = TRUE) %>% kable_styling(latex_options = c("striped"), font_size=5)

问题 I would like to be able to edit LaTeX parts of some Doxygen comments externally with some suitable editor. I would use that only for complex environments. To do that, I figured I can have LaTeX-only files and include them from Doxygen. I did create Doxygen aliases for \begin and \end to make the syntax compatible. (For example, I know how to set-up Emacs/AUCTex for working with LaTeX snippets that have no preamble and document structure.) Is there a way to include the contents of a .tex file

问题 How do I use variables in Latex expressions in R? For example: plot(X, Y, main=expression(R^2)) Will put R with a nice superscripted 2 as main title. But let's say I want it to say 'R^2: 0.5', with 0.5 coming from a R variable. How do I do that? 回答1: The hack of Owen is pretty cool, but not really the common way to do that. If you use bquote , this is actually pretty easy. bquote will do the same as quote , with the exception that everything between .() will be evaluated in a specified

问题 My R Markdown (.Rmd) file looks like this: --- title: Foo author: Marius Hofert header-includes: - \usepackage{bm} output: pdf_document vignette: > %\VignetteEngine{knitr::rmarkdown} %\VignetteIndexEntry{Foo} --- \[ \begin{align} \bm{U}=a\bm{X}\quad\boldmath{U}=a\boldmath{X}\quad\mathbf{U}=a\mathbf{X}. \end{align} \] The output (obtained via R CMD build and the looking in ./inst/doc/*.html ) is this: For getting italics bold vectors, I would like to use \bm{X} in my .Rmd document, but it

问题 I have a table as shown in this figure: The LaTeX code for the table is: \begin{table} \begin{tabular}{ | c | c | } \hline \includegraphics[scale=0.45]{../0_1.eps} & 1.10 2.20 3.30 4.40 \\ \hline \end{tabular} \end{table} I would like to make the four numbers appear in different lines inside the second cell, in order to reduce its width. I wonder how to do it? EDIT: I tried \linebreak, \includegraphics[scale=0.45]{../0_1.eps} & 1.10 \linebreak 2.20 \linebreak 3.30 \linebreak 4.40 \\ But the

问题 I know one of LaTeX's bragging points is that it doesn't have this Microsoftish behavior. Nevertheless, it's sometimes useful. LaTeX already adds an extra space after you type a (non-backslashed) period, so it should be possible to make it automatically capitalize the following letter as well. Is there an obvious way to write a macro that does this, or is there a LaTeX package that does it already? 回答1: The following code solves the problem. \let\period. \catcode`\.\active \def

问题 This is probably best explained with an example. I have the following table, where the "A" cell spans two rows, and the "B" cell spans two columns. \begin{table}[htdp] \begin{tabular}{l|r|r} \multirow{2}{*}{A} & \multicolumn{2}{c}{B} \\ & B1 & B2 \\ a & b1 & b2 \\ a & b1 & b2 \\ \end{tabular} \end{table} _ _ _ _ _ _ _ _ _ _ _ _ |A |_ _ _ _B_ _ _ _| |_ _ _ _|_ _B1_ |_ _B2_ | |a | b1| b2| |a | b1| b2| |a | b1| b2| |_ _ _ _| _ _ _ |_ _ _ _| I would like to center the text in the "A" cell, only.

问题 In a plot in matplotlib I specially want to mark points on the x-axis as pi/2, pi, 3pi/2 and so on in latex. How can I do it? 回答1: The plt.xticks command can be used to place LaTeX tick marks. See this doc page for more details. import matplotlib as mpl import matplotlib.pyplot as plt import numpy as np cos = np.cos pi = np.pi # This is not necessary if `text.usetex : True` is already set in `matplotlibrc`. mpl.rc('text', usetex = True) fig = plt.figure() ax = fig.add_subplot(1, 1, 1) t = np

问题 I'm trying to create a table in Latex but without success. I tried different solutions but no one solves my problem. I would like create a table like the picture below: Can anyone show how to do this in latex please? 回答1: One first sketch may be the following: \documentclass{article} \usepackage{multirow} \begin{document} \begin{tabular}{|c|c|c|c|c|c|} \hline \multirow{3}{*}{A} & \multicolumn{2}{c|}{User B} & % \multicolumn{2}{c|}{User C} & \multirow{3}{*}{D}\\ \cline{2-5} & \multicolumn{2}{c

问题 In LaTeX you can easily reference a section by using \label{} next to a section and then \ref{} to create the reference. However, the reference only includes the number of the section, or the page with \pageref{} . I would like to insert a reference containing the text of the section. Example: \section{My Section} \label{section:my} This is a reference to Section~\ref{section:my}. The output is the following: 1. My Section This is a reference to Section 1. I would like to have: This is a
