In-Depth Information
With
read.xls()
, you can load from other sheets by specifying a number for
sheet
:
data
<-
read.xls(
"datafile.xls"
, sheet
=
2
)
Both the xlsx and gdata packages require other software to be installed on your computer. For
xlsx, you need to install Java on your machine. For gdata, you need Perl, which comes as stand-
ard on Linux and Mac OS X, but not Windows. On Windows, you'll need ActiveState Perl. The
Community Edition can be
obtained for free
.
If you don't want to mess with installing this stuff, a simpler alternative is to open the file in Excel
and save it as a standard format, such as CSV.

See
?read.xls
and
?read.xlsx
for more options controlling the reading of these files.
