post hoc in repeated measures of anova
Hallo, I have this dataset with repeated measures. There are two
within-subject factors, "formant" (2 levels: 1 and 2) and "f2 Ref" (25
levels: 670, 729, 788, 846, 905, 1080, 1100, 1120, 1140, 1170, 1480,

and 2). The response variable

taking rows from data.frames in list to form new data.frame?
Hi,
I am having a problem figuring out how to extract a subset of rows. I
have a list with 68 similar data.frames. Each data.frame is 500 rows
by 5 columns. I want to take one row from each data.frame based upon
the data in a particular column (i.e. it matches a symbol). For
example:
> str(database)
List of 68
$ X2011.01.11:'data.frame': 500 obs. of 5 variables:

Question on CAR appendix on NLS
The PDF file on the web, which is an appendix on nonlinear regression
associated with the CAR book, is very nice.
When I ran through the code presented there, I found something
odd. The code does a certain model in 3 ways: Vanilla NLS (using
numerical differentation), Analytical derivatives (where the user
supplies the derivatives) and analytical derivatives (using automatic
differentiation). The
