A couple of points. First, since you know the format statement, perhaps you control the Fortran program. Then, it might be nicer to introduce whitespace between the data items, which would serve two purposes: making read.table() work on the data set and making it easier for humans to check the data file more easily.

Second, you could look at read.fortran() -- a function that takes a lightly modified Fortran format specification as an argument. That seems even better for your purposes than read.fwf.
