hip_fwf_positions {hipread}

Specify column-specific options for hipread

Description

Specify column specifications analogous to readr::fwf_positions(). However, unlike in readr, the column type information is specified alongside the column positions and there are two extra options that can be specified (trim_ws gives control over trimming whitespace in character columns, and imp_dec allows for implicit decimals in double columns).

Usage

hip_fwf_positions(
  start,
  end,
  col_names,
  col_types,
  trim_ws = TRUE,
  imp_dec = 0
)

hip_fwf_widths(widths, col_names, col_types, trim_ws = TRUE, imp_dec = 0)

Arguments

start, end

A vector integers describing the start and end positions of each field

col_names

A character vector of variable names

col_types

A vector of column types (specified as either "c" or "character" for character, "d" or "double" for double and "i" or "integer" for integer).

trim_ws

A logical vector, indicating whether to trim whitespace on both sides of character columns (Defaults to TRUE, ignored on non-character columns).

imp_dec

An integer vector, indicating the number of implicit decimals on a double variable (Defaults to 0, ignored on non-double columns).

widths

A vector of integer widths for each field (assumes that columns are consecutive - that there is no overlap or gap between fields)

Value

A data.frame containing the column specifications

Examples

# 3 Columns, specified by position
hip_fwf_positions(
  c(1, 3, 7),
  c(2, 6, 10),
  c("Var1", "Var2", "Var3"),
  c("c", "i", "d")
)

# The same 3 columns, specified by width
hip_fwf_widths(
  c(2, 4, 4),
  c("Var1", "Var2", "Var3"),
  c("c", "i", "d")
)
