I'm trying to generate 50+ graphs using the UScensus2000tract data.  I
need to access the data for just about all of the states, so I was
hoping to create a simple loop that will take the relevant state from my
data and load the associated census data from the UScensus2000tract
package.   Below is a sample of what I'm trying to do.  Any suggestions
are much appreciated.

 

stores=read.table(paste(path,"\\Store
List.txt",sep=""),header=TRUE,sep="\t")

city=stores$City

state=stores$State

city.state=data.frame(city,state)

 

state.temp=city.state$state[1]

tract <- paste(state.temp,".tract",sep="")

data(tract)

Warning message:

In data(tract) : data set 'tract' not found
