Count the Number of Fields per Line

Usage

count.fields(file, sep = "", skip = 0)

Arguments

`file`	a character string naming an ASCII data file
`sep`	the field separator character. Values on each line of the file are separated by this character. By default, arbitrary amounts of whitespace can seperate fields.
`skip`	the number of lines of the data file to skip before beginning to read data.

Description

count.fields counts the number of fields, as seperated by sep, in each of the lines of file read. It is used by read.table; a user will typically have no need for it.

Value

A vector with the numbers of fields found.

Examples

cat("NAME", "1:John", "2:Paul", file = "foo", sep = "\n")
count.fields("foo", sep = ":")
