readr (version 0.1.1)

read_log: Read common/combined log file.

Description

This is a fairly standard format for log files - it uses both quotes and square brackets for quoting, and there may be literal quotes embedded in a quoted string. The dash, "-", is used for missing values.

Usage

read_log(file, col_names = FALSE, col_types = NULL, skip = 0,
  n_max = -1, progress = interactive())

Arguments

file

Either a path to a file, a connection, or literal data (either a single string or a raw vector).

Files ending in .gz, .bz2, .xz, or .zip will be automatically uncompressed. Files starting with

col_names

Either TRUE, FALSE or a character vector of column names.

If TRUE, the first row of the input will be used as the column names, and will not be included in the data frame. If FALSE, column names

col_types

One of NULL, a list, a named list or a string.

If NULL, the column type will be imputed from the first 30 rows on the input. This is convenient (and fast), but not robust. If the imputation fails, you'll need to supply the

skip

Number of lines to skip before reading data.

n_max

Maximum number of records to read.

progress

Display a progress bar? By default it will only display in an interactive session. The display is updated every 50,000 values and will only display if estimated reading time is 5 seconds or more.

Examples

read_log(system.file("extdata/example.log", package = "readr"))
