see queryRCmdCheck() of R.utils. Example:

# Get the 'R CMD check' status, if any
status <- R.utils::queryRCmdCheck()

if (status != "notRunning") {
  cat("The current R session was launched by R CMD check. Status:", status, "\n")
} else {
  cat("The current R session was not launched by R CMD check.\n") }

I haven't tested it with Sweave, but with examples and tests.

R.utils 1.18.0 is on CRAN, but you'd want 1.18.3, because:

Version: 1.18.3 [2012-11-06]
o BUG FIX: queryRCmdCheck() did not detect "tests" evidences when   'R CMD check' was testing multiple architectures.

It may be another couple of weeks before I submit it to CRAN, but in the meanwhile you can grab it via:

source("http://aroma-project.org/hbLite.R"); hbLite("R.utils")

Any feedback (positive or negative) is appreciated.

Hope it helps

/Henrik
