First start by putting it in a function so you can specify the
parameters you want to change.

Hello,
I'd like to automate this script a bit more and cycle several
parameters(both the species and the metric). For example where AnnualDepth
occurs, I need to process about 12 metrics so instead of writing this
entire script 12 times once for each metric I'd like to be able to
automatically get another metric.
Any suggestion will be greatly appreciated.
Currently running Windows XP, R 2.11.1
###
Marsh - cbind(SoilVegHydro, vegcode)
AnnualDepth - Marsh[,'meanAnnualDepthAve']
cattail_0 - Marsh[,'cattail'] == '0' # no need to run for 8
species, automate if possible
cattail_1 - Marsh[,'cattail'] == '1' # yes need to run for 8
species
spbase.rate.d1 - sum(cattail_1)/(sum(cattail_1) + sum(cattail_0) )
annualDepth.density - density(AnnualDepth) # this line needs either
interactively defined or automatically cycle thru a number of metrics
cattail.d0.density - density(AnnualDepth[cattail_0])
cattail.d1.density - density(AnnualDepth[cattail_1])
approxfun (cattail.d0.density$x, cattail.d0.density$y) - cattail.d0.f
approxfun (cattail.d1.density$x, cattail.d1.density$y) - cattail.d1.f
p.d.given.AnnualDepth - function(AnnualDepth, spbase.rate.d1)
{
p1 - cattail.d1.f(AnnualDepth) * spbase.rate.d1
p0 - cattail.d0.f(AnnualDepth) * (1 - spbase.rate.d1)
p1/(cattail_0+cattail_1)
}
x - 1:1292
y - p.d.given.AnnualDepth(x, spbase.rate.d1)
plot (x, y, type='l', col='red', xlab='Mean Annual Depth',
main=c(Cattail), ylab='estimated\nProbability(cattail|AnnualDepth)')
plot (cattail.d0.density, col ='red', lty= 1, main = )
lines(cattail.d1.density, col = 'blue', lty=1)
lines(annualDepth.density , col='black', lty = 1)
legend(2000, 0.0023, c(No Cattail, Cattail, Mean Annual Depth),
