internal link in pdf report

Pdf report with summary and detail pages. First page is a summary page about performance of cars with cylinders, say 4, 6, 8. Is it possible to have 4, 6, 8 as a internal link and jump to desired detail page when click on Cylinders column on the first page display table? Thanks,

Hi @tjcnnl1,

I wasn't able to use your specific example because it isn't a reprex. When pasting R Markdown content, place it inside 4 back-ticks to avoid the text being treated as literal markdown.

Here is an example that should get you started, let me know if you have any questions. Basically I created a table which includes hyperlink references to Table 1 and Table 2. Then, each table is given a unique label to refer to it by.

Here is some text.

```{r}
library(tidyverse)
tibble::tribble(
  ~text, ~link,
  "First Table", "\\hyperref[tab:id1]{Table 1}",
  "Second Table", "\\hyperref[tab:id2]{Table 2}"
) %>% 
  knitr::kable(format = "latex", escape = FALSE)
```

\pagebreak

```{r}
mtcars %>% 
  head() %>% 
  knitr::kable(caption = "\\label{tab:id1} Here is my sweet caption for Table 1", escape = FALSE)
```

\pagebreak

```{r}
mtcars %>% 
  tail() %>% 
  knitr::kable(caption = "\\label{tab:id2} Here is my sweet caption for Table 2", escape = FALSE)
```

mtcars %>% 
  tail() %>% 
  knitr::kable(caption = "\\label{tab:id2} Here is my sweet caption for Table 2", escape = FALSE)
```

Got it. Hopefully, this post is easier for you to show jumping pages. Thanks a lots!

The page jumping function works perfect. Thank you so much! I need to get that page but keep the page layout without change. Here is the real code used in the report generation. I want to click on any row in description column, say math, and jump to math page. Again, thanks much

This is a sample report for school subjects evaluation in pdf format. It has summary and detail pages. The first page is report description.  2nd page is a subject table with 4 rows as example (it has more then 40 rows in real). I want to have a internal link column, say SubjectID, and jump to desired detail page when click on it. For example, when click on CAB-01, it leads to Math detail page. I've used 'glue' to create a label, but some parts are missing; it don't work for me. Help needed. Thanks!

It is hard to offer good advice for such a complex example. It takes a while just to understand the document itself. In general it is best if you can boil down the problem to a minimal reproducible example (i.e. the least amount of code necessary to reproduce the issue).

Anyway, in your case it seems like you are using the hyperlinks incorrectly. For a hyperlink to work it needs two things, (1) a starting point and, (2) an end point, or in other words, the link you click on and its target location. You have created the link (though there were some issues with the code), but you do not have any target locations - so the links are pointing to something that doesn't exist.

Here is a simple demonstration of how to create links and locations:

---
title: "Hyperlink Example"
output: pdf_document
linkcolor: blue
---

This is a sentence with a \hyperlink{target}{clickable link}.

\pagebreak

This is the \hypertarget{target}{target location}.

Try rendering this and seeing how it works.

Note: You can basically achieve the same effect with \label{id} and \hyperref[id]{some text}, but the principle is the same, you need a link (created by \hyperref) and a target (created by \label).

Reprex just stands for reproducible example. It's just a short-hand way of describing whether or not someones post is easily reproducible by the person trying to help.

Your original post looks like it is close to being a reprex, you just need to edit the original post and put 4 back-ticks (usually found below the ESC key on the keyboard) in a line before the start of your R Markdown content, and 4 back-ticks after the last line.

This will keep the R Markdown as literal text and not try to format it as it if were standard markdown text in your post.

Putting 4 back-ticks before and after, as shown below, stops the content contained therein to be formatted on this website. Note, when you do this, you won't see the four back-ticks, I have purposefully made them visible for illustrative purposes.

I am not good on R and thought you could copy/paste my R markdown code to your RStudio environment. Sorry, I don't know how to use reprex. Based on my code, would that be too much to ask step by step instructions to send my code that you are able to use? Thanks again!

Pdf report with summary and detail pages.  First page is a summary page about performance of cars with cylinders, say 4, 6, 8. Is it possible to have 4, 6, 8 as a internal link and jump to desired detail page when click on Cylinders column on the first page display table?
