Yes, if you want to know in R code.

Or is it better to test something in R.version, say os?
Not 'os' (the OS is the same), but 'arch' changes. Just as
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

call 'cbind', based on the attribute
f<- function(...) {get first attribute; maybe or maybe not call 'cbind'}
I thought of (ignoring "deparse.

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

I'd like to use this to specify appropriate linker arguments when
building the RMySQL windows package.

So if you want to match these things, you should use POSIXct or any
other numeric-based format (as POSIXct
