Hi again all,
Several replied ASAP that I also needed reshape loaded and not just
reshape2.
Hmmm tried that and I had some output but not the correct format.
What I need is to run simulations of time overlap between species as per
the simulation program data input constraints:
The basis for the simulations is a species by _time-use matrix in which
species are arranged in rows, and time intervals are arranged
chronologically in columns.___ TimeOverlap only uses text tab-delimited
files with no headings for columns or rows.Empirical data must be
specified in proportional abundances (0 to 100) and totals for each
species should be the same (100%).
With the existing code the result was rows were correct for species but
dates were used for columns rather than the times.
The input file read has long format 4 columns - species; location; date;
time.
It dawns on me I may need to have a sub sample of the main data set by
Location ID first then have the code run but for time values and not dates.
I need to tweak this a bit more to see if I can figure that out as well.
I will have many repetitions of this dat reformatting so it is important
I get the code correct one time so I can run this on the gazillion or so
data sets accumulated.
Rather than use reshape can I use _recast_ in place of cast and stick
with reshape2?
