zTreeTables(filelist, tables = c("globals", "subjects"), sep = "\t",
	zTree.silent=getOption("zTree.silent"),
	zTree.encoding=getOption("zTree.encoding"))

Arguments

filelist

a vector of 'z-Tree' (xls-) filenames.

tables

a vector of table names. If you leave this empty, globals and subjects will be read. If you set tables=NULL, all tables will be read.

sep

Field separator. '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

The default encoding is "LATIN1".

Value

A list of all tables (e.g. "globals", "subjects", etc.)
