Spatial communication affects people every day, yet few people have even heard of it. It takes into account the physical distances between people as they interact and converse with one another. One of the most groundbreaking developments in the field of spatial communication was the notion of "personal reaction bubbles;" the oft-used phrase "personal space" is a byproduct of this idea.

R Create a Spatial Bubble Plot That Overlays A basemap of the US and other spatial layers as needed
6/12/2014 5:30 am Culture & Society

I'm trying to produce a nice bubble plot overlaid on top of a basemap of the US (i could import a shapefile if that is preferred but i've been using the R basemaps.

library(ggplot2,sp,raster,maps,mapdata,maptools,ggmap,rgeos)
myData =
data.frame(name=c("Florida","Colorado","california","Harvard","Yellowstone"),
                lat=c(28.1,39,37,42,44.6), 
                long=c(-81.6,-105.5,-120,-71,-110),
                pop=c(280,156,128,118,202))

Using this code below, that i adapted from another stack overflow post (Create bubble plot in R using satellite map), i am able to overlay a bubble plot on a map of the US. However this renders very slowly, the extent is too tight, it is bounded in a box, i'm not able to add other layers to the plot from what i can tell, and the base map is thick and not visually clean.

xy <- myData[,c("long", "lat")]
nl <- getData('GADM', country="USA", level=1) #raster data, format
SpatialPolygonsDataFrame
nl <- gSimiplify(nl, tol=0.01, topologyPreserve=TRUE)
# coercing the polygon outlines to a SpatialLines object
spl <- list("sp.lines", as(nl, "SpatialLines"))
SPDF <- SpatialPointsDataFrame(coords=xy, data=myData)
coordinates(myData) <- c("lat", "long")
projection(SPDF)<- "+proj=longlat +ellps=WGS84 +datum=WGS84
+no_defs +towgs84=0,0,0"
coordinates(SPDF)[1:5,] #retrieves spatial coordinates form the
dataframe
bubble(SPDF, "pop", sp.layout=spl, main="This is It!")

I can draw a nice basemap using this code. I add points to the map but they are not sized by the pop column in my data. And i can add additional layers to this map. But can i control the size of the points and the symbol itself like i can using a bubble plot?

map(database= "world", ylim=c(45,90), 
    xlim=c(-160,-50), col="grey80", 
    fill=TRUE, projection="gilbert", 
    orientation= c(90,0,225))

coord <- mapproject(myData$lon, myData$lat,
proj="gilbert",orientation=c(90, 0, 225))
points(coord, pch=20, cex=1.2, col="red") 

Can anyone please guide me towards the best way to plot a bubble map in R where i can adjust the fill and outline of the symbols in the bubble map, And i can add a clean basemap, that i can a) control the colors of (fill and lines) and b) add additional layers to (for instance another shapefile layer).

Thank you in advance for any advice.


Spatial agent models / spatial emergent behaviour [on hold]
Culture & Society

I am trying to use R to model grids of agents that change their decisions based on the decisions of other agents in their direct proximity. Basically - each agent looks to the other agents around him on the grid, and might change its behaviour based on the the actions around him. I have included some sample dinky-toy code per below to show (one iteration) of such dynamic.I am wondering whether a) there is an elegant manner to address the boundaries of the grid (currently the t+1, i+1 code does
Conversion of MySQL spatial query with intermediate tables to PostGre spatial query

Hi All,
I have the following query which was based on a working query in MySQL:
(dont be afraid of the size of the query you see below, later on I will concentrate on part of this query)
