zTreeSbj: Read '.sbj' files generated by 'z-Tree' into R

In zTree: Functions to Import Data from 'z-Tree' into R

Description

Read '.sbj' files which are written by the Microsoft Windows program 'z-Tree'. The latter is a software for developing and carrying out economic experiments (see <http://www.ztree.uzh.ch/> for more information).

Usage

zTreeSbj(files, sep = "\t", zTree.silent=getOption("zTree.silent"),
	zTree.encoding=getOption("zTree.encoding"),ignore.errors=FALSE)

Arguments

files	A vector of 'z-Tree' .sbj filenames
sep	'z-Tree' uses "\t" as a separator. If you have a manipulated file, you might need to change the separator.
zTree.silent	If TRUE, generates less verbose output.
zTree.encoding	zTree writes text files and seems to use latin1 (windows-1252) encoding for these files.
ignore.errors	Usually, zTreeSbj stops with an error when it detects a wrong encoding. With ignore.errors=TRUE it only generates a warning.

Value

A data frame with one entry for each subject.
