Put workspace in docx

Workshop documents

Documents designed for workshop or classroom participation typically provide information, examples, and prompts with room for participants to respond. The functions described here provide space in a document for written responses.

Both functions work by creating and returning a ggplot2 object.



This function allows the author of Rmd to docx documents to insert a vertical white space of specified height.

The white space is an empty ggplot2 object. The only assignment is the panel background, made with theme(panel.background = element_rect()).

The usage is put_gap(col = NULL, fill = NULL) to specify the color of the rectangle border and its fill. Defaults are “transparent”.

The dimensions of the gap are determined when it is printed. For example, to create a 0.75 inch gap in an R Markdown output document, we set the dimension in the knitr code chunk header,

```{r fig.height = 0.75}

produces this output:

With color and fill arguments and an optional width argument in the code chunk header,

```{r fig.height = 0.75, fig.width = 6}
put_gap(col = "black", fill = "gray")

Here’s an image from a Word document where space for written responses was created using put_gap().


A gap can also be used to force a page break. Alternatively, Norbert Köhler shows how to insert page breaks using Word Styles, see R Markdown: How to insert page breaks in a MS Word document


put_axes() creates and prints an empty, 2-dimensional coordinate axes using ggplot2 with no scales, no tick marks, and no axis labels.

Usage is put_axes(quadrant = NULL, col = NULL, size = NULL).


# all 4 quadrants

# quadrant 2

# quadrant 1
put_axes(1, col = "blue", linewidth = 2)

# quadrant 3

# quadrant 4
put_axes(4, col = "red", linewidth = 2)

# two adjacent quadrants

# two adjacent quadrants


The size of the figure is determined when printed, e.g., using knitr in an R Markdown script, the figure height in inches is set with the fig.height code chunk option.

```{r fig.height = 2}

The default aspect ratio is 1, though it can be edited using coord_fixed() from ggplot2.

put_axes() +
  coord_fixed(1 / 2) # ratio of y/x


The graph object can be edited using the usual ggplot2 annotations. For example, to place some text in the middle of the graph,

p <- put_axes() +
  annotate("text", x = 0.5, y = 0.5, label = "quadrant I")

We can add text labels to label the axes using annotate()

p <- put_axes() +
    x = c(1, 0), 
    y = c(0, 1), 
    label = c("x", "y"), 
    vjust = c(1, 0.5), 
    hjust = c(1, 1.5), 
    fontface = "italic"

Or we can use the usual labs() after resetting the theme axis.title,

p <- put_axes() +
  theme(axis.title = element_text()) +
  labs(x = "new x", y = "new y")

If we use annotate() and the label exceeds the data rectangle, we can make the plot margin larger and override the plot clipping.

p <- put_axes(2) +
    x = c(-1, 0),
    y = c(0, 1), 
    label = c("Re", "Im"), 
    vjust = c(1.5, 0.5), 
    hjust = c(0, -0.5), 
    fontface = "italic"
  ) + # top, right, bottom, left
  theme(plot.margin = unit(c(0, 5, 2, 0), "mm"))

# override clipping
pp <- ggplot_gtable(ggplot_build(p))
pp$layout$clip[pp$layout$name == "panel"] <- "off"


These functions help create printed documents with space for written responses. Options are limited; authors needing more control can create their own inserts using ggplot2 or other graphics engine.
