R/ls_recodeTable_to_equations.R
ls_recodeTable_to_equations.RdThis function takes a dataframe with LimeSurvey (LS) variable codes
and values, and builds a nested set of LimeSurvey Equation Manager (LSEM)
if/then/else equations where the variable code in each row (in the
varCodeCol) is compared to the corresponding value (i.e. the value in
the same row in the valueCol column) using the operator specified in that
row in the operatorCol column (or the == operator, if no operator is
specified). In the case of a match, the value in the corresponding
recodeToCol column is returned. If there is no match, the comparison
on the next row is evaluated, all the way down. If nothing matches, the
elseExpr is returned.
