[R] using inspect with a TermDocumentMatrix to convert to a data frame

Dear Erin,

For the issue of printing big data.frame, you could define a customized
`print.data.frame` in the user environment

to prevent R prints all the data. For example:

```r
print.data.frame <- function(df) {
  base::print.data.frame(head(df))
  cat("===\n")
  base::print.data.frame(tail(df))
}
```

Hope that helps.

Regards,
Wush
