I have a dataset with geometry through the sf package included with lat and lon information. I also have a heat map created as a result of the dataset
Overlay<-stat_density2d(aes(x = df$LONGITUDE, y = fd$LATITUDE, fill = ..density..), geom = 'tile', contour = F, alpha = .5)
Is there a way to join the heat map density color values into the point file?
st_join(Shots1B,Overlay)
gives me an error
Error in st_join.sf(Shots1B, Overlay) :
second argument should be of class sf: maybe revert the first two arguments?
Reproductive dataset to follow the process. Overlay is based on the result of this dataset here.

I'm quite new to R and I have this task I need to complete. I would like top produce a plot like the following.
I did it with excel but I don't like the appearance, I think I can get a better plot using ggplot2.
The sample data for this plot:

My Data frame can be found in the following link
https://drive.google.com/file/d/1IQl_KKNONI7WiBloSmS_ZepVlakRBpUt/view?usp=sharing
Try reshaping and using geom_line():
library(dplyr)
library(tidyr)
library(ggplot2)
#Load data
df <- read.csv('SampleData.csv',stringsAsFactors = F)
#Code
df %>%
mutate(date=as.Date(date,'%m/%d/%Y')) %>%
pivot_longer(-date) %>%
ggplot(aes(x=date,y=value,group=name,color=name))+
geom_line()+
scale_x_date(date_labels = '%Y-%m-%d',breaks = '5 year')+
scale_y_continuous(breaks = seq(0,10,by=1))
Output:
I have a SpatialLinesDataFrame of streets in Malawi and Shapefile of Malawi country. The problem is that the coordinates of some parts of one of the streets are located in the Malawi lake (and it's clearly not possible in the reality), so I think there are some problems between the shapefile and the SpatialLinesDataFrame. How can I correct the coordinates of the SpatialLinesDataFrame so that they can overlap correctly? The shapefile I am using for Malawi can be found here : mwi_adm_nso_20181016_SHP.zip (the name of the file I am using is mwi_admbnda_adm3_nso_20181016.shp).
Here the code to create the SpatialLinesDataframe of the street that has segments in the lake.
# download the shapefile of Malawi
mySHPM <-
shapefile(
paste(
path,
"/mwi_admbnda_adm3_nso_20181016.shp",
sep = ""
)
)
# subset to focus on the area where the street is
mySHP <- mySHPM[mySHPM$ADM2_EN %in% c("Karonga", "Rumphi"), ]
# define the SpatialLinesDataframe for the street that goes in the lake

Thanks for your help!
I have data frame that contains variable with set of coordinates, which supposed to be a polygon. I’d like to try to convert it into sf geometry polygon, but I have little idea how to achieve this goal.
Data looks like this:

You need to parse these text strings into numbers, then convert into polygons. This function creates an sfc object that contains the polygons these vectors describe:
polygonise <- function(strings) {
do.call(c, lapply(strings, function(x) {
cutstring <- unlist(strsplit(x, "\\[|\\]"))
cutstring <- cutstring[nchar(cutstring) > 3]
sf::st_sfc(sf::st_polygon(list(do.call(rbind,
lapply(strsplit(cutstring, ", "), as.numeric)))))
}))
}
So, for example, we can do:
polygons$geometry <- polygonise(polygons$polygon)
ggplot(polygons) + geom_sf(aes(geometry = geometry), fill = "forestgreen")
Your solution works perfectly on the example I provided. However, when I try to use your function on real data I get an error ("'MtrxSet(x, dim, type = "POLYGON", needClosed = TRUE)': polygons not (all) closed ". Perhaps my coordinates are flawed? Sorry for that, but I’m pretty new to R.
a <- read_csv("https://raw.githubusercontent.com/slawomirmatuszak/Covid.UA/master/dzielnice.csv")
b<- polygonise(a)
I'm trying to figure out how to clip a polygon based on a linestring. I have estimated the range of a terrestrial animal and this range estimate extends into the ocean. I'd like to clip out any parts that extend into the ocean.
I'm using rnaturalearth to get the coastline, which returns a series of linestrings
library(lwgeom)
library(rnaturalearth)
library(rnaturalearthhires)
library(sf)
cl10 <- ne_coastline(scale=10,returnclass='sf')
poly1 is an sf polygon of the home range estimate. (To load this from wkt below, you need to add the final ')"', which is not displaying for some reason.)

poly1 <- st_sf(st_as_sfc(wkt))
I use this to extract out the relevant linestring.
box <- poly1 %>% st_bbox %>% st_as_sfc
sa_coast <- cl10[st_intersects(box,cl10,sparse=FALSE),] %>%
mutate(len=st_length(geometry)) %>%
filter(len==max(len))
From here, I want to clip poly1 using sa_coast. However I can't figure out how this can be done. Here is what the coast and range look like. The northern part of the map is ocean, the southern part is land.
ggplot() +
geom_sf(data=poly1,fill=NA,color='red') +
geom_sf(data=sa_coast) +
xlim(st_bbox(poly1)['xmin'],st_bbox(poly1)['xmax']) +
ylim(st_bbox(poly1)['ymin'],st_bbox(poly1)['ymax']) +
theme_classic()
I don't think that st_intersection() works, because this returns the multiline string that intersects with poly1
What I want is a multipolygon that has the water (top area of the figure) clipped out. See below, the geom returned by st_intersection() is in blue.
intr <- st_intersection(poly1,sa_coast)
ggplot() +
geom_sf(data=poly1,fill=NA,color='red') +
geom_sf(data=sa_coast) + #,mapping=aes(color=rowid)
geom_sf(data=intr,color='blue') +
xlim(st_bbox(polys)['xmin'],st_bbox(polys)['xmax']) +
ylim(st_bbox(polys)['ymin'],st_bbox(polys)['ymax']) +
theme_classic()
Here is the solution I finally figured out. Thanks to #JindaLacko who gave me the idea to use st_polygonize on a linestring. My linestring did not close however, so st_polygonize did not work. The trick is to clip the linestring using the polygon's bounding box, then use the min corner of the bounding box as a point on the linestring, and then close the linestring with it's first point. You can then turn this into a polygon.
Clip the coastline to size of the bounding box of the polygon.
sa_clip <- st_intersection(st_as_sfc(st_bbox(poly1)),sa_coast)
ggplot() +
geom_sf(data=st_as_sfc(st_bbox(poly1)),fill=NA) +
geom_sf(data=sa_clip) +
theme_classic()
Get the min corner of bounding box
corner <- st_bbox(poly1)[c('xmin','ymin')] %>% st_point %>% st_sfc(crs=4326)
Cast the linestring to points, append the corner, close the linestring, turn into polygon.
pts <- sa_clip %>% st_geometry %>% st_cast("POINT")
sa_poly <- c(pts,corner,pts[1]) %>% st_combine %>% st_cast('LINESTRING') %>% st_polygonize
Now, you can clip the polygon.
clipped <- st_intersection(sa_poly,poly1)
ggplot() +
geom_sf(data=sa_poly,fill='red',alpha=.2) +
geom_sf(data=poly1,fill='blue',alpha=.2) +
geom_sf(data=clipped,fill='purple',alpha=.2) +
theme_classic()
For clipping a linestring & a polygon use sf::st_intersection()
Consider the example on RStudio Community site, where I used it to determine an intersection of polygons of some random North Carolina (a popular dataset) counties with the 36th parallel.
https://community.rstudio.com/t/how-to-change-color-of-polyline-when-it-is-passing-a-polygon-in-leaflet-package-using-r/37033/3?u=jlacko
Edit: an intersection of linestring and polygon will be a linestring.
If the desired output is a polygon consider calling sf::st_polygonize() on your linestring. It will turn it into a polygon, which will return a polygon upon intersection with the other polygon.
