  It's hard to answer this without a reproducible example, and it's generally harder to get answers about less-used/more specialized packages. I'm going to guess that at least some of your dates are not in the same format as specified (from the manual page: default is "%d/%m/%Y %H:%M:%S" --
you can change this with the 'dtformat' argument).

  You shouldn't need to specify arguments to the function that are the same as the defaults: I would expect that

seal <- readTDR("file location and name here",

    subsamp=1, concurrentCols=4:5)

would work equally well (or poorly ...)
