Natively read and write Excel (.xls) files. Supports Windows 32-bit only (atm).
A new version has been released:
-- changes --
o read.xls
- new arguments 'checkNames'
- recognize NA values according to a new 'naStrings' argument
- recognize NaN values
- recognize 'true', 'false' (not case-sensitive) as logical when
determing a class for data.frame column;
when the value in the first cell is an integer, a numeric will be
assumed nevertheless
- colnames are more consistent with R usage (X, X.1, V1, etc.)
- matrices always have rownames (as in data.frame). With FALSE
rownames become (integer) 1:length(rows)
- duplicated rownames no longer accepted
- allow data with one row which is defined as being the colnames
(i.e. no 'real' data row)
- colNames/colClasses can optionally contain an entry for the column
used for the rownames
o write.xls
- error (instead of warning) when length of character colnames
doesn't fit data
- write NA values according to the 'naStrings' (scalar) argument
- write NaN values as 'NaN' string (instead of ending as #ZAHL!)
- colNames can optionally contain an entry for the column used for
the rownames
o template location moved
- new: R_HOME/library/xlsReadWrite/template/TemplateNew.xls
- (old/erronous: R_HOME/library/xlsReadWrite/libs/template, reported
by B. Ripley)
o RUnit tests extended, loading simplified
o improve examples and run them on the regular version, polish docu
-- bugfixes --
o file: path may be absolute or relative to the current working directory.
The 'relative' part was broken (feedback from several people)
o xls.getshlib: sometimes existing dll could not be replaced. Now uses path
of loaded dll instead of lib.loc and path (reported by G. Grothendieck)
o use .Platform$r_arch for shlib path and R.version$platform in xls.getshlib
to make pkg compatible with R2.12dev (reported and tips by B. Ripley)
o several fixes related to row/colnames in special cases (without data)
-- 'ecosystem' --
o issue tracking (developer) link change:
- http://dev.swissr.org (was: https://redmine.swissr.org)
- allow guest login and directly mention credentials
Cheers,
Hans-Peter
