Hi List,
Using Lattice, I have created a plot of histograms showing Fork Length by
Year. The plot shows the histograms in 3 columns and 5 rows. Using the
as.table=T function I can get the years to start on top. However, what I
would like to do is have the first year start in the top left (column 1, row
1; as it is now) and add the subsequent histograms to the plot going down
the column and then over by row (example and current code is shown below).
Is this possible? I have spent a great deal of time searching, and have not
found any clues. Any help/ideas would be greatly appreciated.
For example, what is being done now:
1974 1975 1976
1977 1978 1979
1980 1981 1982
and what I am hoping for:
1974 1977 1980
1975 1978 1981
1976 1979 1982
Thank you kindly,
Les
