You can use the pipe command to read data:
msci <- read.table(pipe("python steve/python/msciintl.py"),sep=",",header=T,
as.is=T)
I use this metaphor quite a bit for loading data.

Subject: [R] R more Unix-like?
Is there a way to stream data into R so that it can be used in a
command pipe?
Most Unix commands read data via standard input and read the script
from the command line. For example:
$ seq 1 10 | sed -e 's/^/foo /'
$ seq 1 10 | awk '{print "foo " $1}'
$ seq 1 10 | perl -lane 'print "foo $F[0]"'
In contrast, R seems to read the script from standard input, thereby
preventing streaming data through that file descriptor. In reading
through the man page for R and R-intro.html I haven't seen anything
obvious to change this behaviour. Is it possible?
Pointers to references would be greatly appreciated.
Regards,
- Robert
