Read SEER Fixed Width File

Reads a SEER fixed width file using the column dictionary in the provided SAS file (see seer_read_col_positions() for more details). Note that the results are the raw data reported by SEER with no transformations -- all fields are imported as character strings by default. You can change this by specifying the col_types argument using readr column specification via readr::cols(), or you can set col_types = NULL to let readr guess the column type.

seer_read_fwf(file, col_positions = seer_read_col_positions(), ...,
  col_types = readr::cols(.default = readr::col_character()))

Arguments

file	Path to SEER fixed width file.
col_positions	SEER column positions, see seer_read_col_positions().
...	Arguments passed on to readr::read_fwf locale The locale controls defaults that vary from place to place. The default locale is US-centric (like R), but you can use locale() to create your own locale that controls things like the default time zone, encoding, decimal mark, big mark, and day/month names. na Character vector of strings to use for missing values. Set this option to character() to indicate no missing values. comment A string used to identify comments. Any text after the comment characters will be silently ignored. skip Number of lines to skip before reading data. n_max Maximum number of records to read. guess_max Maximum number of records to use for guessing column types. progress Display a progress bar? By default it will only display in an interactive session and not while knitting a document. The display is updated every 50,000 values and will only display if estimated reading time is 5 seconds or more. The automatic progress bar can be disabled by setting option readr.show_progress to FALSE.
col_types	Specification for column types, default is to return all as character strings. Use NULL to rely on readr or see readr::read_fwf() for further details.
