Hi there,
I encounter the following problem with getGenerics
when Rgraphviz is installed:
which(!sapply(getGenerics(), isGeneric))
#graph Rgraphviz graph Rgraphviz
# 105 106 107 108
so, getGenerics returns twice graph and Rgrapviz as being generics, when they
are not:
Dear R developers---of course, I have my own function that does this,
but I think this would be useful for others, too. summary() already
returns the first moment, and I would hope most of us think of the
standard deviation as a pretty common summary statistic.
not to clutter this mailing list,
I think it would be even more useful if we could get Sweave to easily
produce PNG figures instead of just PDF/EPS. In the current state of
things, making PNG versions is more cumbersome than making PDF versions,
so I'm not surprised that most people don't go to that trouble most of
the time.

Hi,
I have a very large data file(GB) from which I only want to extract one
column to draw histogram. This would be done several times, so I would like
to ask if there is anyway to plot this using R from the linux command line,
something look like this
cut -f1 xxx.txt |RplotHist
Thanks and

Good afternoon Hang,
This is an example of what I've done with a csv file with a header
which is too big to read into memory.
# this is a file with about 50 columns and 28 million records
ap.fnam - 'p2_all28m_records.csv'
# lets just explore the columns in Addresspoint...

Dear list, dear Henrik,
I find myself often reconstructing matrices from the result of rowSum (matrix)
etc. I therefore propose a new argument, drop, for these functions:
drop = TRUE (default) is the current behaviour. With
drop = FALSE length (dim (x)) and dimnames are preserved and the
