Usage

read_tier(
  raw_lines,
  col_types = NULL,
  col_names = NULL,

  left_justified = "EXCODE",
  guess_max = 1000,
  store_v_fmt = TRUE,
  read_only = NULL
)

Value

a tibble containing the data from the raw DSSAT output

Arguments

raw_lines

a character vector that includes the contents of a single tier of data (including headline, but excluding version stamp and other header information) from a DSSAT output file

col_types

One of NULL, a cols() specification, or a string. See read_fwf or vignette("readr") for more details.

col_names

A character vector of column names; primarily helpful for cases where there are no white spaces between column names within the header line

na_strings

a character vector of string to represent missing values

left_justified

A character vector of column names that should be left justified

guess_max

An integer indicating the maximum number of lines that should be used to guess the type of a column

store_v_fmt
