[R] logical 'or' on list of vectors

Suppose I have a list of logicals, such as returned by lapply:

Theoph$Dose[1] <- NA
Theoph$Time[2] <- NA
Theoph$conc[3] <- NA


Is there a direct way to execute logical "or" across all vectors? The following gives the desired result, but seems unnecessarily complex.
