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.
