I'm trying to generate a report with each row of a tibble printing vertically in a table on its own page using a for loop. The tables are printing fine, but I want to put headers at the top of each page (and eventually, text). Since the line of code to print the header (which appears as a header in my own document but not in my reprex, not sure why) is above the line of code to print the table, using kable, I expect the header to print above the table. I suspect kable is doing something I don't understand behind the scenes but I cannot determine what.

What am I doing wrong, and how may I print headers at the top of each page?

I've provided below: a screenshot of the current output.

Relevant portion:

I have successfully included in an R/exams .Rmd file several graphics made in TikZ. The same does not happen when I try to include a plot under pgfplots using include_tikz(). Whenever \begin {axis} and \end {axis} are included, beware of the error "! LaTeX Error: Environment axis undefined".

In the RStudio console the legend appears: "This is pdfTeX, Version 3.14159265-2.6-1.40.21 (TeX Live 2020) (preloaded format = pdflatex) restricted \ write18 enabled.entering extended mode", even having enabled in TexStudio write-18. None of these messages appear when I include other TikZ graphs other than pgfplots.

Any TikZ graph works when run in TexMaker or TexStudio, which indicates that it is not a problem of the absence of LaTeX libraries or packages.

I include a part of my code, adapted from https://www.latex4technics.com/?note=1HCT:

I want to visually align the labels for "Cats" and "Apples" so that they appear on the same "line", and to do the same for "Dogs" and "Apples", rather than having the animal label appear in the middle of the list of fruit labels. Is this possible using graph hbar?

In Gatsby v2 you could enable this syntax className={styles["block__element--modifier"]} by adding the following code to gatsby-node.js:

I'm using the posterdown package in R to generate a HTML Poster and render it as a PDF.

I have a table in my Rmd file, however the caption is really small. Is there a way to increase the size of the caption?

Secondly, I would also like to move the title and affiliation in the header slightly down (so that its more in the center of the header. Is there a way to do that?

Here is a snippet of my Rmd file

The R/exams package supports including TikZ graphics using its function include_tikz(), e.g., as shown in the automaton and logic exercises shipped with the package.

After getting include_tikz() to work for these exercises (see: Why are TikZ graphics rendered with exams2pdf but not with exams2moodle?) I tried to create my own exercise. However, so far this does not work yet. My code is:

suppose I have an .R file tmp.R with markdown tags, e.g.

I have prepared a .Rmd file with some R code, which I knit in Rstudio into a .md file. This .md file will, in turn, be pushed into a GitHub repository in order to produce a GitHub page (using the GitHub pages system) with a specific layout.

The issue I have is that when I specify the layout in my Rmarkdown file, e.g. with the following code:

I would like to render multiple objects of the function quiz of the library learnr using a loop in one chunk. The R is compiling the html-markdownfile without problems, but the rendering is not correct. It is rendering text and not a question as it is supposed to.

This is my reproducible code, currently not rendering correctly:
