[R] na.strings in readLines or is.na?

When reading a data set into R using readLines, na.strings="-99.99" is ignored. Is there an equivalent command for readLines? Alternatively, either immediately after reading into R or once the data set has been converted to a data frame, what is the appropriate command (or appropriate use of is.na) to convert my -99.99s to NAs?
Thanks,
Ben Osborne
