[R] open xlsx file using read.xls function of gdata package
Dear all, I am trying to open excel files using the gdata package. I can do that using a .xls file, but the same file, containing the same data, formatted in .xlsx gives error (R does not recognize the pattern from where to start reading the data). Doen anybody knows whether it is possible to read .xlslx with this package? Am I missing another package to implement the reading of the .xlsx? Thank you Luigi PS: this is the error I get:> my.file <- "array.xlsx" > my.data<-read.xls(+ my.file, + sheet="sheet x", + verbose=FALSE, + pattern="row name", + na.strings=c("NA","#DIV/0!"), + method="tab", + perl="perl" + )> Warning message:In read.xls(my.file, sheet = "sheet x", verbose = FALSE, : pattern not found The verbose version runs like this: ?array.xlsx? to tab file ?/tmp/Rtmp2tAjzz/filef06102dd018.tab? ... Executing ' '/usr/bin/perl' '/home/gigiux/R/x86_64-pc-linux-gnu-library/3.0/gdata/perl/xls2tab.pl' 'array.xlsx' '/tmp/Rtmp2tAjzz/filef06102dd018.tab' 'sheet x' '... Loading 'array.xlsx'... Done.

[R] open xlsx file using read.xls function of gdata package
I had poor luck with gdata. I have had better luck with XLConnect. There is no single best package for this, since each seems to leverage efforts made in other languages (so there are non-R configuration requirements to keep working) and Excel is a proprietary moving target. In general YMMV when it comes to Excel data. In most cases I just export the data to CSV and avoid the issue. --------------------------------------------------------------------------- Jeff Newmiller The ..... ..... Go Live...

You might try the readxl package - it's only available on github but it reads both xlsx and xls. All going well, it should be on its way to CRAN next week.
