[R] month increment for chron dates

I have a vector of over 7,000 chron dates in the format mm/dd/yy. I need to increment each date in the vector by a standard number of months. Lapply with seq.dates is working OK; this increments the vector x by 3 months: dates(unlist(lapply(x, function(g) seq.dates(g, by=months, length=4)[4])))
