http://stat.ethz.ch/R-manual/R-patched/library/base/html/NA.html in
the R documentation. Apparently "systems typically have many different
NaN values. One of these is used for the numeric missing value NA, and
is.nan is false for that value" (

)
In this case the function call would be y <- mean(x, na.rm = TRUE)
