kandi X-RAY | cowplot Summary
The cowplot package provides various features that help with creating publication-quality figures, such as a set of themes, functions to align plots and arrange them into complex compound figures, and functions that make it easy to annotate plots and or mix plots with images. The package was originally written for internal use in the Wilke lab, hence the name (Claus O. Wilke's plot package). It has also been used extensively in the book Fundamentals of Data Visualization.

QUESTION
I am plotting a series of identically sized plots in a grid using patchwork. My grid is 5 x 6, expect for the final 2 rows I have only 4 plots in the row not 5. I want to have empty plots so that the plots are displayed as a regular grid.
...ANSWER

takes a design argument where empty fields can be place with #
QUESTION
I've built this new ggplot2
geom layer I'm calling geom_triangles
(see https://github.com/ctesta01/ggtriangles/) that plots isosceles triangles given aesthetics including x, y, z
where z
is the height of the triangle and
the base of the isosceles triangle has midpoint (x,y) on the graph.
What I want is for the geom_triangles()
layer to automatically provide legend components for the height and width of the triangles, but I am not sure how to do that.
I understand based on this reference that I may need to adjust the draw_key
argument in the ggproto
StatTriangles
object, but I'm not sure how I would do that and can't seem to find examples online of how to do it. I've been looking at the source code in ggplot2
for the draw_key
functions, but I'm not sure how I would introduce multiple legend components (one for each of height and width) in a single draw_key
argument in the StatTriangles
ggproto
.
ANSWER
Answered 2022-Jan-30 at 18:08I think you might be slightly overcomplicating things. Ideally, you'd just want a single key drawing method for the whole layer. However, because you're using a Stat
to do the majority of calculations, this becomes hairy to implement. In my answer, I'm avoiding this.
Let's say I'd want to use a geom-only implementation of such a layer. I can make the following (simplified) class/constructor pair. Below, I haven't bothered width_scale
or height_scale
parameters, just for simplicity.
QUESTION
I've generated a scatterplot with marginal histograms on the x and y axes, using this extremely helpful answer from @ClausWilke (reproduced below).
...ANSWER
Answered 2022-Jan-20 at 13:48You could:
- Change
element_blank
toaxis.text.x = element_text(colour = "white")
so axis text is the same colour as the plot background so not visible, forcing the axis label to be on the vertical position as the main plot. - Include a dummy plot with
NULL
in the call toplot_grid
And, in response to additional question in comments... - use
grid::nullGrob
to make the right hand side plot panel the same height as the main plot panel.
QUESTION
I am trying to trim the white space from a ggplot map plot that was created using geom_sf()
. I have found multiple resources discussing removing white space when saving a plot using ggsave()
. I am hoping to remove the white space without having to save it, though.
Removing white space using ggsave()
- R ggplot, remove white margins in ggsave/ggplot
Please find below a reproducible example:
...ANSWER
Answered 2022-Jan-12 at 19:14Can share more about what you're trying to accomplish? You say you want to remove whitespace, but you also want the plot to be at the bottom left of whitespace. What is your ultimate goal here? Let me know if I missed something.
I believe the whitespace is added outside of your ggplot based on your graphic device and ggplot margins. You can control the ggplot margins in theme()
(like in this question/answer). You could remove the whitespace by defining your graphic device to the same dimensions as your ggplot object.
If you wanted to place the plot at the bottom left of whitespace, you could define your graphic device space and then plot within that area with one of your favorite plot layout tools. For example:
QUESTION
How can I modify the multiplot function to fit graphs that use coord_fixed()
without white space between columns in Shiny plotOutput?
This is a small reproducible shiny app with the problem:
...ANSWER
Answered 2022-Jan-06 at 04:03With coord_fixed
we are fixing the aspect ratio to 1 by default. To make the spacing between columns the dimensions of the plot need to change. I added two sliders to control the height and width. I don't know a formula to make this happen automatically without the user manual intervention though. For example, for two columns and 3 plots, making the width twice the hight works.

QUESTION
I'm just trying to plot the ROC curves in a plot grid in Rstudio, the neural net models are all working but the ROC curves just won't go in a grid layout, they plot individually but there's a lot more than this and the markdown file would be like 20 pages long. I've reduced all models to two neurons as dummy-data to make it run quickly, only setwd() and the read in data lines need to be adapted.

QUESTION
Hi all I am working with a little dataframe to build some plots in ggplot2
. My dataframe is df
and I include it as dput()
at the end. I have the plots and the problem rises when I use patchwork
. I want the final plot without spaces so that the line in the middle, which is an axis, can join the plots together. Here is the code:
ANSWER
Answered 2021-Dec-03 at 18:19You can do this you can adjust + plot_layout(widths = c())
or you could adjust the margins using & theme(plot.margin = ...)
however, I don't think plot.margin
will work in this case.
To implement widths
into your plot, you will need to add a spacer plot and use widths
to adjust the spacer so that the plots full join together
