dexi_value {DEXiR} | R Documentation |
Conversion of a string to a "DEXi value" (see DEXiR-package) according to "new"
DEXi syntax rules. In .dxi
files, this syntax is used in ALTERNATIVE
and
RULE
XML tags. Examples of possible options include:
x result ------------------------------+------------------------------------------------- NULL or "" NULL "*" "*" a string starting with "undef" NA "2" a single ordinal value, c(2) in this case "2.1" a single number, c(2.1) in this case "1:3" interval, equivalent to c(1, 2, 3) "{0;2;3}" a value set, equivalent to c(0, 2, 3) "<0;0.3;0.7>" a value distribution, distribution(0.0, 0.3, 0.7)
dexi_value(x, add = 0)
x |
character(1). |
add |
A numeric constant to be added to the result. Useful
when converting DEXi's zero-based representation to one-based representation used in R,
which requires the setting |
A single integer or real number, an integer numeric vector, or a distribution.
