Very, very, very bad solution.
as.matrix can change silently your data to unwanted format, complete.cases()==T
is silly as Peter already pointed out.
I use

Why not use complete.cases() ?

Hello all,
I am attempting to automate an analysis that I developed with ArcInfo
using R and the gdal and geos packages (or any other) if possible.
Here is the basic process
I have a shape file (lines) that defines the limits of all of the
projects
# download.file() Seems to put the xlsx file onto hard drive.
download.file(http://www.udel.edu/johnmack/data_library/zipcode_centroids.xlsx;,
zipcode_centroids.xlsx)
trying URL 'http://www.udel.edu/johnmack/data_library/zipcode_centroids.xlsx'
Content type
Add the argument mode=wb to your call to download.file(). On Windows
this means to use 'binary' format - do not change line endings.

No one is doubting that it worked for you in this instance. What Peter D. was
criticizing was the construction :

Suggest (strongly) that you move this question to r-sig-geo. Much more
appropriate there, and more people there are more familiar with this kind
of work. But ... I suspect you want gIntersection(), not gIntersects().

Anthony,
XLSX won’t read an XLS file. Additionally, the legacy Java that is required for
the xlsx package really effs up my computer. Have to reinstall my OS to fix it.

Dear Rodolfo,
It's apparently the case that at least one of the columns of the model
matrix for your model is perfectly collinear with others.
There's not nearly enough information here to figure out exactly what the
problem is, and the information that you provided certainly falls short of
I didn't dispute whether '%%' may be useful -- I just pointed out that it
is slow. However, it is only part of the problem: 'filter()' and
'select()', although aesthetically pleasing, also seem to be slow:
