| multinominal2logical {sharpshootR} | R Documentation |
Convert a single multinominal, site-level attribute from a SoilProfileCollection into a matrix of corresponding logical values. The result contains IDs from the SoilProfileCollection and can easily be joined to the original site-level data.
multinominal2logical(x, v)
x |
a |
v |
the name of a site-level attribute that is a factor with more than 2 levels |
A data.frame with IDs in the first column, and as many columns of logical vectors as there were levels in v. See examples.
