Hi 오건희 ,
You seem to be supplying a character vector - names(termFrequency) - 
as the "x" argument to qplot. Making a wild guess that these names are 
actually numbers, perhaps:

as.numeric(names(termFrequency))

will work. If the wild guess was wrong, perhaps you want to specify 
termFrequency as the first argument. When something like this happens, 
it is often helpful to explicitly name your arguments:

qplot(x=names(termFrequency),y=termFrequency,
 geom="bar", xlab="Terms",stat="bin")+coord_flip()

This will sometimes give a meaningful error message that helps to 
identify what has gone wrong.
