I am using an Rmarkdown to print a table which has a lot of formatting. When I add the add.to.rwo part to get grey and white alternate rows the vertical lines are removed in the grey rows.
How do I correct this? It is very difficult to create a reproducible example but hopefully the same problem will apply to any df (with the correct Latex packages behind it)
Thanks :)
Try comparing these two tables. The first is your table as you coded it, the second is done by pixiedust with the hhline option set to TRUE.

## Quarto
Trying to iterate over each species and print the distributions on slides
```{r}

Here is an option by producing the plots beforehand using purrr based on this discussion:

I'm trying to generate a Word document with figures. I use {officedown} and {officer} packages. I need to do it dynamically, in a loop since I don't know how many figures there will be. This is my Rmarkdown code:

```
```{r}
block_toc(seq_id = "fig")
```
```{r results='asis'}
ttp <- c(3, 7)
test_items <- c("item A", "item B", "item C")
fpars <- lapply(test_items, function(ti) {
fpar(
ftext("Application of "),
ftext(ti),
ftext(" Variable text - describe any test item-related effects"),
ftext(" (see "),
run_reference("fig:results1"),
ftext(")."),
fp_p = fp_par(padding.bottom = 12)
)
})
do.call(block_list, fpars)
```
```{r}
titles <- lapply(seq_len(length(ttp)), function(i) {
sprintf(
"My custom figure caption with %s, having %s side effects",
paste(test_items, collapse = ", "),
ttp[i]
)
})
```
```{r}
tmps <- lapply(seq_len(length(ttp)), function(i) {
tmp <- tempfile(fileext = ".png")
png(tmp, width = 6, height = 5, units = "in", res = 120)
plot(iris[sample(1:150, 30), i + 1:2])
dev.off()
return(tmp)
})
```
```{r}
fpars <- lapply(seq_len(length(ttp)), function(i) {
fpar(
run_autonum(
seq_id = "fig",
pre_label = "Figure ",
bkm = paste0("fig:results", i),
bkm_all = TRUE,
prop = fp_text(bold = TRUE, font.size = 12)
),
titles[[i]],
external_img(src = tmps[[i]], width = 6, height = 5)
)
})
do.call(block_list, fpars)
```
The problem is when I generate the table of figures in the rendered document. It looks like this:
An entry is kept together with the image itself, I don't know why.
I save temporary png files to be able to use them inside fpar function. Using plot function directly inside fpar causes bad effects. Maybe there's another/better way?
I found this construction useful, but unfortunately it puts captions under the figures by default. My goal is figure captions behave more like table captions, i.e. a caption is above a figure.
```{r fig.cap=unlist(titles)}
plot(iris[1:10, 1:2])
```
How can I generate the plots with captions dynamically with {officedown} or {officer} packages?
The only issue is about the last lapply, you need to put the image in a separate paragraph, so a for loop will be easier to stack 2 paragraphs into a list instead of 1 for each iteration.

This is an answer for "how to do it with officer" from scratch.
But the following is much more simple. There is an option fig.topcaption that do the same thing.

library(officedown)
```
```{r}
block_toc(seq_id = "fig")
```
```{r fig.cap = "miaou", fig.topcaption=TRUE}
plot(cars)
```
```{r fig.cap = "ouaf", fig.topcaption=TRUE}
plot(cars)

I'm trying to filter a data frame and then do some simple ggplots off of the data. I've tried to leverage the R studio example on Shiny documents along with the following SO post on the subject:
Reactively filtering/subsetting a data frame in shiny
Here is my code.

data %>%
filter(x %in% input$n_break)
output$table <- DT::renderDT({
cdat()
}, options = list(scrollX = TRUE))
})
```
Can anyone point out where I'm going wrong? When I run the code I get my dropdown box, but that is all. No errors. Just no filtered datatable.
Thanks.
The closing brackets of your reactive are at the wrong place. They should close once you have filtered the data.

```
A remark on the reactive: if you plan to extend this futher, such that the filtered data is used elsewhere, it makes sense to do the filtering in a reactive function. However, if this is not the case I would just do the filtering inside the renderDT:

I am using R Markdown to output to pdf, and I am trying to get a table and a plot aligned side by side horizontally. I can get fig.align = "right" to align the plot to the right of the page, but it is plotted under the table (formatted with kable) and not side by side with it. Any tips?
Here is a way using the TeX package floatrow:
---
title: "Untitled"
header-includes:
- \usepackage{floatrow}
output:
pdf_document:
keep_tex: true
---
\newfloatcommand{btabbox}{table}
\begin{figure}[H]
\begin{floatrow}
\ffigbox{%
```{r, fig.align = "right", echo = F}
plot(mpg ~ hp, data = mtcars)
```
}{\caption{A figure}}
\btabbox{%
```{r, fig.align = "right", echo = F}
knitr::kable(head(mtcars[,1:3]), format = "latex")
```
}{\caption{A table}}
\end{floatrow}
\end{figure}
I prefer the method by Martin, but if you wanted to have a less LaTeX reliant solution, you could convert the table into a grid graphic and plot it as a subfigure:
---
header-includes:
- \usepackage{subfig}
output: pdf_document
---
```{r, fig.cap='two plots', fig.subcap= c('A figure', 'A table'), out.width = '.49\\linewidth', echo = F, fig.align='center'}
library(gridExtra)
library(grid)
plot(mpg ~ hp, data = mtcars)
grid.newpage()
grid.table(head(mtcars[,1:6]), theme = ttheme_minimal())
```
I was able to do this with a combination of the multicol package and minipages. Just another option...
Here's the code:
---
title: "Untitled"
header-includes:
- \usepackage{multicol}
- \newcommand{\btwocol}{\begin{multicols}{2}}
- \newcommand{\etwocol}{\end{multicols}}
output:
pdf_document:
keep_tex: true
---
```{r minipage_funs, echo = FALSE}
## adding minipages in Rmarkdown only seems to work for me when returned from function
fig_table_mp_start <- function() {
return("\\begin{minipage}{\\textwidth}")
}
fig_table_mp_end <- function() {
return("\\end{minipage}")
}
```
`r fig_table_mp_start()`
\btwocol
```{r, fig.align = "right", echo = FALSE}
plot(mpg ~ hp, data = mtcars)
```
```{r, fig.align = "right", echo = FALSE}
knitr::kable(head(mtcars[,1:3]), format = "latex")
```
\etwocol
`r fig_table_mp_end()`
I assume you can play around with padding to make it look pretty.
I want to produce slide dynamically in my Rmarkdown presentation with shiny

But as soon as I uncomment the for loop it doesn't.

#for (i in 1:length(number_of_bins_selected)) {
cat("## New slide \n")
input1_id <- paste(i, "nbreaks", sep = "_")
input2_id <- paste(i, "bw_adjust", sep = "_")
inputPanel(
selectInput(input1_id, label = "Number of bins:",
choices = c(10, 20, 35, 50), selected = number_of_bins_selected[i]),
sliderInput(input2_id, label = "Bandwidth adjustment:",
min = 0.2, max = 2, value = 1, step = 0.2)
)
renderPlot({
hist(faithful$eruptions, probability = TRUE, breaks = as.numeric(input[[input1_id]]),

dens <- density(faithful$eruptions, adjust = input[[input2_id]])
lines(dens, col = "blue")

Isn't it possible to create slides on a for loop ?
