On page 3

yields 1264 records but on page 14 when I run the code

I get only 1210 records

Top of code |
Incorrectly begins code with:
geocodeAddresses<-function(myStreets){
'appid<-'<put your appid here>'
myGeoTable<-data.frame(
should be:
geocodeAddresses<-function(myStreets){
appid<-'<put your appid here>'
myGeoTable<-data.frame(
(note the ' removed at the start of appid<-)

2/3rds down the page |
The command
> geoTable[geoTable$Y==max(geoTable$Y),]
fails because geoTable$Y is still a factor at this point. geoTable$Y is converted to a numeric column in the section immediately following.

The last line on the page,
> help.search("mean")
Shoud read:
> help.search("mean")
As written without the quotes, that command returns an error.
