Hi,
QUESTION TOPIC #1
I have some data I want to plot on a map. But what I have are home addresses:
street, City, State, complete postal code--i.e 95377-1234. Is there a way to
plot this data or do I need latitudinal and longitude coordinates? If so how do
I convert them? Is there a package that will do the conversion in R?
QUESTION TOPIC #2
I was trying to experiment with this code that I found at the site below but
got a message that indicated that the "map" function is not found. So I tried
installing the maps package but got the below message. Is there an alternative
way of doing this (please refer to URL below)?
# The message I got:
> install.packages("map")
Warning message:
package 'map' is not available (for R version 2.15.0)
# The code I tried to run:
states <- data.frame(map("state", plot=FALSE)[c("x","y")])
colnames(states) <- c("Lon","Lat")
ggplot(states, aes(x=Lon, y=Lat)) + geom_path()
+ geom_point(alpha=0.6,size=0.3,data=subway)
# Where I got the code from and also an image of what I am attempting to do
(please enter this in your URL)
