Read in legacy-style Yplant input files into a special object, to be used in any analysis in YplantQMC.
The function constructs an object of class plant3d
, based on Yplant input files (.p and .l/.lf). Various
methods exist for plant3d
objects, in particular plot.plant3d
and
summary.plant3d
.
For batch analyses, the function readplantlist
reads a number of files at a time, and stores the results in
a special list (of class plant3dlist
).
Three plants are provided with YplantQMC
(and automatically loaded) :toona
,
pilularis
and sugarmaple
. See plantexamples
.
To learn about the format of P and L files, read the detailed account on the Prometheus wiki (Pearcy, Falster & Duursma 2011): http://goo.gl/Hmyv6.

pfile,lfile |
Name of .p and .l (or .lf) file. |
qfile |
Optionally, instead of a pfile, a Q file format. See Details. |
multiplier |
Multiplies length dimensions, e.g. to change units. |
X0,Y0,Z0 |
New x,y,z coordinate of the stem base. |
warn |
If TRUE, writes warnings of minor issues with P file format. |
quiet |
If TRUE, no messages are ever shown. |
pfiles,lfiles |
Vectors of .p files and .l files. |
lpk |
Optionally, a 'leafplantkey' file. See Details. |
For legacy Yplant users (Pearcy and Yang 1996, see http://goo.gl/Hmyv6), you will find that constructplant
is much more robust with respect to malformed input files. It will also attempt to write error messages when things go wrong.
The Q file format is an alternative to .P files, and is much easier to use if the virtual plant does not have stem sections. There are seven columns:
Coordinates of the leaf base
Angle and azimuth of the normal to the leaf surface
Orientation (azimuth angle) of the midrib
Leaf length
The file is space-delimited (such as the output of write.table
), and includes column headers (exactly named as above).
The leafplantkey file is a convenient way to organize a large number of plant files. This is a simple comma-separated text file without headers. The order is pfile,lfile (without quotes). For example, a "leafplantkey.txt" file may look like this:
1 2 3 4 5 6 7 8 9 10 11 12 | acaflo1.p,acaflo.l
acaflo2.p,acaflo.l
acaflo3.p,acaflo.l
acamyr1.p,acamyr.l
acamyr2.p,acamyr.l
acamyr3.p,acamyr.l
acasua1.p,acasua.l
acasua2.p,acasua.l
acasua4.p,acasua.l
acasuaR02.p,acasua.l
acasuaR05.p,acasua.l
acasuaR09.p,acasua.l

In the case of constructplant
, an object of class plant3d
. For readplantlist
,
an object of class plant3dlist
(which is simply a list of objects as generated by constructplant
to ease batch analyses).
