Thanks.
FWIW, quick write up on package in general here: https://blog.ouseful.info/2016/05/02/when-documents-become-databases-tabulizer-r-wrapper-for-tabula-pdf-table-extractor/
I note that the area settings passed to the area function aren't the exact same ones as those displayed by the Tabula app.

With the update I just pushed, give this a try for that example:
x1 <- extract_tables(tmp, guess = FALSE, pages = 2, area=list(c(200, 10, 700, 120)), method = "data.frame")
str(x2)
## List of 1
## $ :'data.frame': 27 obs. of 2 variables:
## ..$ LAP : chr [1:27] "1 " "2 " "3 " "4 " ...
## ..$ TIME: chr [1:27] "15:05:38" "3:02.377" "2:43.433" "1:44.375" ...
x2 <- extract_tables(tmp, guess = FALSE, pages = 2, area=list(c(200, 10, 700, 120)), method = "data.frame")
str(x2)
## List of 2
## $ :'data.frame': 27 obs. of 2 variables:
## ..$ LAP : chr [1:27] "1 " "2 " "3 " "4 " ...
## ..$ TIME: chr [1:27] "15:05:38" "3:02.377" "2:43.433" "1:44.375" ...

So:
- area bounds thing seems to be fixed;
- scrape works for multiple pages specified;
- omitting
pagesattribute throws an error:
May 2, 2016 4:14:09 PM org.apache.pdfbox.util.operator.pagedrawer.FillEvenOddRule process
WARNING: java.lang.ArrayIndexOutOfBoundsException
java.lang.ArrayIndexOutOfBoundsException
Error in area[[p]] : subscript out of bounds
(Thanks for the quick fix, btw:-)

Can you let me know if this is still happening with the current version?

If I remove the pages argument from a test where it works with multiple pages, it still seems to fail with Error in area[[p]] : subscript out of bounds

This should be fixed now. For your example file:
> x1 <- extract_tables(tmp, guess = FALSE, pages = NULL, area=list(c(200, 10, 700, 120)), method = "data.frame")
> str(x1)
