[R] grid.table and expression in table body?

[baptiste Auguié]

I added a parse argument to grid.table so that when switched to TRUE (default FALSE) all the text strings are interpreted as expressions (inspired by ggplot2::geom_text),

d <- data.frame("alpha", "beta")
grid.table(d, parse=T)

you'll need revision 258 of gridExtra for this to work (googlecode now, r-forge in the following days, CRAN in the next stable version).

HTH,
