   Min. 1st Qu. Median Mean 3rd Qu. Max.   0.222 4.780 7.550 7.780 10.200 21.600

The mean of this variable DOES NOT ROUND to the value shown in the summary output.

> options(digits=6)
> mean(wm$Spd1)

[1] 7.77733
> summary(wm$Spd1)

   Min. 1st Qu. Median Mean 3rd Qu. Max.   0.222 4.780 7.550 7.780 10.200 21.600

This is still wrong. Also, the minimum value is 0.2221, which should have been printed in full given digits=6.
