Legend based on geom rather than aesthetic with ggplot

Asked 2021-Dec-04 at 09:01

The idea here is to draw a legend for each geom with the same aesthetic. In the example below the legend generated assumes that these two different layers are in the same scale, resulting in this map.

I want, as a result, that the legend in the graph is separated in two, so I can change these with a scale_fill_* for each layer.

I'm aware of this solution: https://stackoverflow.com/a/24874007/11056037, but I'm looking for a more elegant and scalable way to do this.

Sounds as if you are looking for the ggnewscale package which allows for multiple scales and guides for the same aesthetic:

tm_text produces duplicate text in tmap

I'm trying to do a map using library tmap and this dataset.

Following this discussion, I'm using the following simple code:

...

ANSWER

Answered 2021-Nov-13 at 18:33

Your code to display the map with the tmap library is fine. The problem is that the sf object polygons_regioes_adm_sp has a mixture of POLYGON and MULTIPOLYGON. So, you just need to simplify the sf object by running the st_cast() function.

As for the projection problem, you just need to specify the EPSG code to assign a recent form of the CRS to the sf object (NB: as for the warning message - cf.below - do not worry, it is fine)

So, please find below the code to display correctly the names of the administrative regions.

QUESTION

Coloring a map with different color depths in ggplot2

Asked 2021-Feb-25 at 17:20

I'm trying to plot a map of brazil colored with a specific color, "#2D3E50". However, using this color on the map to color from the smallest area (light shade) to the largest area (dark shade) is not working. See below the chosen color that I am trying to insert for the different proportions.

...

ANSWER

Answered 2021-Feb-25 at 17:19

The RColorBrewer package does not contain a color palette called # 2D3E50. Therefore, it is enough to elaborate a sequence of colors with their respective shades, that is, a color for low values and high values, being these: low = "white", high = "#2D3E50".

QUESTION

How to customize legend in ggplot for multiple layers in a map?

Asked 2020-Oct-15 at 17:38

I'm trying to fix my caption but I'm having trouble creating it. I wanted a caption for the classes (fill), the shape limit (color), the points (color) and the grid (fill=NA). I put them all in aes () but I don't have the expected result. Can anybody help me? Thanks!

...

ANSWER

Answered 2020-Oct-15 at 17:38

Your desired result could be achieved like so:

I moved all fill=NA and color=NA out of the aes() statements. As usual if you want to fix a color, fill or more generally any aes on a specific value then it's best to put it outside of aes() except for the case that you want it to appear in the legend.
Set the so called key_glyph, i.e. the icon drawn in the legend, of the "point" layers to "point".

As these steps also removed the black border around the fill keys I added a guides layer to get that back. Personally I would remove the black border, but hey, it's your plot. (:

Calculate distance from a border with R

I need to calculate the distance between the border of a set of municipalities, from other municipalities in the state of Minas Gerais. The idea is to conduct a regression discontinuity design (RRD) and the border is my cut off.

Here is an example of database:

ANSWER

Answered 2020-Oct-11 at 14:24

You have too many NA values to do a true discontinuity design, like you showed above.

Map.

Because of that, the best thing to do might be to just calculate nearest neighbors by category:

I don't understand spatial.data at all. I have been studying but I'm missing something.

What I have: data.frame enterprises with the columns: id, parent_subsidiary, city_cod.

What I need: the mean and the max distance from the parent's city to the subsidiary cities.

Ex:

ANSWER

Answered 2020-Aug-25 at 06:08

Great problem. I looked at it for a little while. Then I came back and looked some more after thinking about it. The mean was not calculated. Only the distances were determined from each parent to its subsidiaries.

The data was binded - the cities data and the data frame data. Then the new df was mutated to add the centroid data for each point on the surface.

The df was split by id and resulted in a list of 8 df's. Each df contained separate parent with related subsidiaries. (1:4, 1:3, 1:4, 1:2, .... )

A loop with a function cleaned up the 8 df's, and calculated the distance from each parent to each subsidiary.

I checked the distance of the first df in the list against values for distances from a website. The distances of df1 were nearly identical to the website.

The output is shown at [link]

geom_sf and geom_point, how to assign colors based on the points inserted on the map to the corresponding types in the legend?

I need to insert multiple points on the map using ggplot. I would like to display in the legend the amount of colors and shapes corresponding to the types registered in points$types. I also need the value of point$obj to be printed on the map along with the insertion of the coordinate. However, I managed to get to that code, but I can't assign the colors and shapes.
