Some other major tech companies have in the past widely use Runnable R
Archives (".Rar" files), similar to Python .par files [1], and integrate
them completely into the proprietary R package build system in use there.
I thought there were a few systems like this that had made their way to

Which makes joining or grouping data sets with 64 bit identifiers
problematic.

The lack of 64 bit integer support causes lots of problems when dealing
with certain types of data where the loss of precision from coercing to 53
bits with double is unacceptable.
Two packages were developed to deal with this: int64 and bit64.
You may need to find archival versions of these pac
Yes, I'm also strongly in favor of having an option for this. If
there was an option in base R for controlling this we would just use
that and get rid of the separate RProtoBuf.int64AsString option we use
in the RProtoBuf package on CRAN to control whether 64-bit int types
from C++ are returned to

The columns that are "supposed" to be numeric are those that can fit
into a numeric data type. Previously that was not always the case

The simplest case would be:
int num_rows = Rf_length(VECTOR_ELT(dataframe, 0));
int num_columns = Rf_length(dataframe);
There may be edge cases for which this doesn't work; would need to
look into how the dim primitive is implemented to be sure.

I think none of these examples describe a zlib compressed data block inside
a binary file that the OP asked about, as all of your examples are e.g.
prepending gzip or zip headers.
Greg, is memDecompress what you are looking for?

Most operating systems have tools which allow you to audit the resources
used by a running process, for example the 'lsof' (list open files) command
on Unix and MacOS X. Or, for more complex dynamic tracing, the DTrace
framework again on MacOS X or BSD Unix.

Simon, do you have some examples of packages with this attribute? Removing
the hard-coding of paths in base R and Rscript is one of the many local

Lots of very sensible policies here. I have one request as someone
who has in several cases had to involve company lawyers over
intellectual property issues with packages on CRAN -- the first bullet
point on ownership of copyright and intellectual property rights could
be strengthened further.

FYI, the new int64 package on CRAN gets this right, but is of course
somewhat slower since it is not doing hardware 64-bit arithmetic.
x <- c(rep(180003L, 1000), -rep(120002L, 1500))
library(int64)
sum(as.int64(x))

What are the ramifications of setting up user signal handling to allow
the use of e.g. alarm(2) to send a SIGALRM to the R process at some

Indeed thanks to ripley@ for submitting it. I don't see a note in the
NEWS file and it would be nice to point this out as fixed since others
may have run into this problem. Could someone submit something like
this as well?
