plotting timeseries with data gaps
Hi, I made a timeseries-class object, containing unevenly sampled data. However, some gaps are too big to use any interpolation. Yet I would like to plot the timeseries, with the data-points joined by a standard line '-', except in the long gaps (otherwise, it does some sort of unphysical straight bridge-like lines)... 18 Jan 2010 12:00

eigenvalues of the covarience matrix (princomp)
Hey Peter, another question; My intuition is that running the analysis on zscores will not change the returned eigenvectors, but will only change the eigenvalues, and thus the order in which the eigenevectors are returned.
