Hi Gregory,
is this what you want? Ok, not the most elegant way
I am helping a fellow worker get R up and running, and he has run into a
peculiar problem I've not encountered in previous install situations.
From the Rconsole menu choice, he can set CRAN mirror to USA CA2, but when he
selects load packages a very truncated list of packages appears (many

Among those users of Primer, stress values greater than 0.3 are
interpreted as questionable. Using both isoMDS and metaMDS (vegan
package), the stress values returned are much higher using my own data
and using examples provided in R Help. For example Rstress = 8.3, and
the stressplot r2 = 0.99
If you submit these lines, you end up with variable vare.dis. I want
to export vare.dis to csv. Stuck I am.
library(vegan,logical.return = TRUE) #return=true verifies package is
available
library(MASS,logical.return=TRUE) #return=true verifies package is
available

What am I failing to understand here?
The script below works fine if the dataset being used is
DNase1 - DNase[ DNase$Run == 1, ] per the example given in
help(nlrob).
Obviously, I am trying to understand how to use nls and nlrob to fit
curves to data using R.
