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,\\StoreList.txt,sep=),header=TRUE,sep=\t)
city=stores$City
state=stores$State
city.state=data.frame(city,state)
Or more succinctly,
city.state - stores[ , c('city', 'state')]
state.temp=city.state$state[1]
tract - paste(state.temp,.tract,sep=)
I believe you need get() here, but I would think you'd need a path to the
state file you want to grab. See ?get
