You would have to work out the > field widths, but it would seem to be pretty straightforward). 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. -- Mike Prager, NOAA, Beaufort, NC * Opinions expressed are personal and not represented otherwise. * Any use of tradenames does not constitute a NOAA endorsement. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

[R] Reading a file created with Fortran
Colleagues, I am trying to read a file written by Fortran. Several lines of the file are pasted below: 101 06e+050280.9777.484208.18147.20.246350.4020.7308717.882600 1 1 101 0.500280.9777.484208.18147.20.246350.4020.7308717.882600 0 0 101 100280.9777.484208.18147.20.246350.4020.7308717.882600 0 0 101 1.500280.9777.484208.18147.20.246350.4020.7308717.882600 0 0 101 200280.9777.484208.18147.20.246350.4020.7308717.882600 0 0 101 2.500280.9777.484208.18147.20.246350.4020.7308717.882600 0 0 101 300280.9777.484208.18147.20.246350.4020.7308717.882600 0 0 101 400280.9777.484208.18147.20.246350.4020.7308717.882600 0 0 101 600280.9777.484208.18147.20.246350.4020.7308717.882600 0 0 The fortran format statement is: (E3.0,E4.0,E5.0,E1.0,3E6.0,E5.0,E7.0,E5.0,E7.0,E6.0,E3.0,2F2.0) The read.table command cannot parse the table correctly because there are no spaces between columns. Although readLines reads the file, it does not separate the elements into columns. I suspect that the "what" option of "scan" accomplishes my intent although its implementation is poorly document in help (or perhaps I am too dense to understand it). Can anyone advise as to an efficient means to read these data and separate into columns? Thanks.
