If called with both x1 and x2, the difference between the two is returned.That is, k=0. One of the things that used to perplex me as a newby to R was how to format a number as a percentage for printing. Note that: this function uses the first class level to define the “event” of interest. Be however it may, it wasn't until 2013 that the first pipe %.% appears in this package. In theory the survival function is smooth; in practice we observe events on a discrete time scale. Tolerance function It selects the least complex model within some percent tolerance of the best value. 2. xtable (xtable package) Generate a nicely formatted table for LaTeX or a basic table for HTML. The n th percentile of an observation variable is the value that cuts off the first n percent of the data values when it is sorted in ascending order..
