dexi_option_value {DEXiR} | R Documentation |
Conversion of a string to a "DEXi value" (see DEXiR-package) according to "old"
DEXi syntax. In .dxi
files, the old syntax is used with OPTION
XML tags.
The reason for replacing the old with the new syntax (see dexi_value()
) was
that the old syntax can not unambiguously represent value distributions.
