POSIXlt is a list and it is not a list of dates or times, it is a list
of

[1] "sec" "min" "hour" "mday" "mon" "year" "wday" "yday"
"isdst"
So if you want to match these things, you should use POSIXct or any
other numeric-based format (as POSIXct

Hi,
Is this sufficient?
if (.Machine$sizeof.pointer==4){
cat('32\n')
} else {
cat('64\n')
}
Or is it better to test something in R.version, say os?
I'd like to use this to specify appropriate linker arguments when
building the RMySQL windows package.

No, the above is perfect, as it also works on other platforms to distinguish
32-bit and 64-bi

I am trying to get an attribute of the first argument in a call to a
function whose formal arguments consist of dots only and do something, e.g.,
call 'cbind', based on the attribute
f<- function(...) {get first attribute; maybe or maybe not call 'cbind'}
I thought of (ignoring "deparse.

In kmeans() in stats one gets an error message with the default
clustering algorithm if centers = 1. Its often useful to calculate
the sum of squares for 1 cluster, 2 clusters, etc. and this error
complicates things since one has to treat 1 cluster as a special case.
A second reason is that easil

Yes, if you want to know in R code.
if (.Machine$sizeof.pointer==4){
cat('32\n')
} else {
cat('64\n')
}

Not 'os' (the OS is the same), but 'arch' changes. Just as
