ssind: Indicator values of all species in data set "sveg"

Description

For each species in "sveg" all 8 indicator values are taken from the "Flora Indicativa by" Landolt et al. (2010). These are ranks on a 1 to 5 scale (except for M), but for some indicators half steps are used as well. Scores zero (0) are either undefined or unknown and must be treated as missing values
