Fills in predictor, response, and effort matrics for time series data where there are multiple multivariate time series. Time series gjam is still under development.

fillNA |
fill new rows in ydata with NA; otherwise interpolated value |
fillTimes |
insert rows for missing times: integers values in column |
Fills missing times in xdata, ydata, edata
. If fillTimes = TRUE
insert rows for missing times, including a times = 0
, which serves as a prior mean for times = 1
. groups
must be uniquely defined. Within groups
can be sequences
, as when there is a time series for groups
for each year.

row numbers in new data where each time series begins, with times = 0 |
timeLast |
row numbers in new data where each time series ends |
rowInserts |
row numbers for all inserted rows |
noEffort |
rows for which effort is zero, except times = 0 |
