Preventing page breaks when using in long tables exported from xtable()

When using LaTeX's longtable environment it is sometimes desirable to prevent a page break for certain lines in the table. In LaTeX this is done by using * at the end of the row. prevent_pagebreak adds * to specified lines of output from print.xtable.

Usage

prevent_pagebreak(pxtab, lines)

Arguments

pxtab

the output from a call to print.xtable

lines

either a numeric vector of row numbers or "multirow". If the latter then the function will check which lines start with a cell which uses \multirow.
