read_obs.Rd
Read STICS observation file for sole or mixed crops.
read_obs(dirpath = getwd(), filename = NULL, mixed = NULL)
dirpath | Directory path |
---|---|
filename | A vector of observation file name(s). Optional, see details. |
mixed | (optional) Is the simulation on mixed species (boolean) |
A data.frame (sole crop) or a list of two data.frames (mixed crops) of
the STICS-formated observations. Return NULL
if no files were found,
or more files than useable.
If filename
is not specified (or equal to NULL
), the
function tries first to match the mod_s*
names for the same \*.obs
names, and then to use the .obs
file if there is one only
(used for sole crops or for both mixed crops). If there are no .obs files,
or two but not specified for reading, the function returns NULL
If mixed
is not specified (or equal to NULL
), the function
tries to read the number of species from the input files.
