Check whether a parse table contains a tilde
Check whether a parse table contains a tilde
is_tilde_expr(pd, tilde_pos = c(1, 2)) is_asymmetric_tilde_expr(pd) is_symmetric_tilde_expr(pd)
pd |
A parse table. |
tilde_pos |
Integer vector indicating row-indices that should be checked for tilde. See 'Details'. |
A tilde is on the top row in the parse table if it is an asymmetric tilde
expression (like ~column), in the second row if it is a symmetric tilde
expression (like a~b).
