title: How can I load CSV data points onto a shapefile in R?
body: <p>I am trying to plot Starbucks locations from CSV data onto a city shapefile that I've loaded in. I want to essentially create a heat map or simple scatter plot with the Starbucks locations on the city shapefile. The csv file has longitude and latitude points.</p>
  
  <p>This is the code I have so far, I'm having trouble with merging the two files together though. Please let me know if you can help!</p>
  
  <pre><code>install.packages("sp")
  install.packages("sf")
  
  library(sf)
  library(sp)
  
  dallas_starbucks &lt;- st_read("STREETS.shp")
  st_geometry_type(dallas_starbucks)
  st_crs(dallas_starbucks)
  st_bbox(dallas_starbucks)
  dallas_starbucks
  
  ggplot() + 
  geom_sf(data = dallas_starbucks, size = 5, color = "white", fill = "blue") +
  ggtitle("Starbucks in Dallas") +
  coord_sf()
  
  starbucks_location &lt;- read.csv("dallas_starbucks_directory.csv")
  head(starbucks_locations)
  
  ----- 
  dallas1 &lt;- merge(dallas_starbucks, starbucks_location, by.x='Longitude', by.y='Latitude')
  </code></pre>
  
  <p>---I've also tried the PBSmapping package, but I'm stuck:</p>
  
  <pre><code>install.packages("PBSmapping")
  library(PBSmapping)
  sbx &lt;- read.csv("dallas_starbucks_directory.csv")
  sbx &lt;- points(sbx$Longitude, sbx$Latitude)
  library(dplyr)

  <p>shapefile: <a href="https://gis.dallascityhall.com/shapefileDownload.aspx" rel="nofollow noreferrer">https://gis.dallascityhall.com/shapefileDownload.aspx</a>
  (City of Dallas Streets)</p>
