I have a dataset composed of a dependent variable (species percent cover) and
a range of abiotic variables (salinity, temperature, pH, water movement
etc). It is a longitudinal study, in which species percent cover was
measured once a month for five months. The abiotic variables were measured
using
Hi R-listers,
I am trying to compare sections of the beach separated from the HTL to the
Veg (east to west), separated into indices (-5 to 30m), HTLIndex. Cross
parallel (north to south) are major beach sections (Rayos 1, 2, 3, 4 and
MNB). I am thinking to do an ANOVA for each independent rectan

Hi,
If you want to take advantage of Josh's example below (using an S4
subclass of data.frame), perhaps you might be interested in taking
advantage of the multitude of useful objects/classes defined in the
bioconductor IRanges package:
http://www.bioconductor.org/packages/release/bioc/html/IRange
Alternatively, you can make a separate S3 class for a data frame with this
attribute -- and then have appropriate, print, plot, etc. methods that
access it. That way, your messy syntax has to be written only once in the
method functions.

Hi Bruno,
It sounds like what you want is really a separate class, one that has
stores information about units for each variable. This is far from an
elegant example, but depending on your situation may be useful. I
create a new class inheriting from the data frame class. This is
likely fraught

Dear all,
I'd like to have a dataframe store information about the units of
the data it contains.
You'll find below a minimal exemple of the way I do, so far. I add a
"units" attribute to the dataframe. But I dont' like the long syntax
needed to access to the unit of a given variable (namely

Hi,
I would like to ask for advice about best statistics method for
my problem.
I was done questionnaire about headache.
My data are:
Y - frequency of symptoms occur - times per month in range <0..30>
(where 30 is daily and zero for never)
and independent variables:
X1 - sex - category {M,F}
X2 -
Perfect, that works well. Thank you for the suggestion.

I have some security alert log data that I'm parsing and doing some stats on.
One of the fields is the "Classtype" which is the enumerated value of the
type of alert found.
classtypes = factor( alerts$Classtype )
fclass_types = table( classtypes )
fclass_types gives me a frequency table of the
