I am trying to plot my coordinates using R. I have tried already to follow different post (R: Plot grouped coordinates on world map ; Plotting coordinates of multiple points
Another option is using the leaflet package (as suggested here). Unlike Google Maps it does not require any API key.
install.packages(c("leaflet", "sp"))
library(sp)
library(leaflet)
df <- data.frame(longitude = runif(10, -97.365268, -97.356546),
latitude = runif(10, 32.706071, 32.712210))
coordinates(df) <- ~longitude+latitude
leaflet(df) %>% addMarkers() %>% addTiles()
