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
