Hello all -
As I progress in R I am trying to automate functions I would have normally farmed out to Excel, SPSS or Statistica. Single factor anova is one of them. For example, a dataset from NIST StRD (http://www.itl.nist.gov/div898/strd/anova/AtmWtAg.html) has two groups:
1 2
107.8681568 107.8681079 107.8681465 107.8681344 107.8681572 107.8681513 107.8681785 107.8681197 107.8681446 107.8681604 107.8681903 107.8681385 107.8681526 107.8681642 107.8681494 107.8681365 107.8681616 107.8681151 107.8681587 107.8681082 107.8681519 107.8681517 107.8681486 107.8681448 107.8681419 107.8681198 107.8681569 107.8681482 107.8681508 107.8681334 107.8681672 107.8681609 107.8681385 107.8681101 107.8681518 107.8681512 107.8681662 107.8681469 107.8681424 107.8681360 107.8681360 107.8681254 107.8681333 107.8681261 107.8681610 107.8681450 107.8681477 107.8681368
The certified values are (I hope the spaces remain intact):
Sums of Mean Variation df Squares Squares F Statistic
Between Instrument 1 3.63834187500000E-09 3.63834187500000E-09 1.59467335677930E+01
Within Instrument 46 1.04951729166667E-08 2.28155932971014E-10
Any assistance you can offer is greatly appreciated. Thanks.
