Here Documents

Description

Read lines and convert into appropriate vector or data frame.

Usage

here(s, drop = TRUE, guess.type = TRUE, sep = NULL, header = TRUE,
     stringsAsFactors = FALSE, trim = TRUE, ...)

Arguments

s	a string
drop	logical: drop empty first and last element
guess.type	logical
sep	NULL or character
header	logical
stringsAsFactors	logical
trim	logical: trim whitespace?
...	named arguments to be passed to read.table

Details

Experimental. (Notably, the function's name may change.)

The function reads a (typically multi-line) string and treats each line as one element of a vector or, if sep is specified, a data.frame.

If sep is not specified, here calls type.convert on the input s.

If sep is specified, the input s is fed to read.table. Additional arguments may be passed through ....

Value

a vector or, if sep is specified, a data.frame
