R help - Oct 2012 - Error: object 'CO2' not found

Hello:

I am new on R, this is the first time I work with it,
I am trying to run some R example to get learn of them,
but, I have a problem when running the example below:

http://stat.ethz.ch/R-manual/R-patched/library/datasets/html/zCO2.html

CO2.Qn1 <- CO2[CO2$Plant == "Qn1", ]
SSasympOff(CO2.Qn1$conc, 32, -4, 43)  # response only
Asym <- 32; lrc <- -4; c0 <- 43
SSasympOff(CO2.Qn1$conc, Asym, lrc, c0) # response and gradient
getInitial(uptake ~ SSasympOff(conc, Asym, lrc, c0), data = CO2.Qn1)
## Initial values are in fact the converged values
fm1 <- nls(uptake ~ SSasympOff(conc, Asym, lrc, c0), data = CO2.Qn1)
summary(fm1)
I am facing the error below:
> ### ** Examples
>
> CO2.Qn1 <- CO2[CO2$Plant == "Qn1", ]
Error: object 'CO2' not found
Execution halted


I have the packages required (stats,graphics) and they are loaded as

library() and search() shows.

Any clue about it?


Thanks,
Humberto.

You need to load the dataset.

First, run

data(CO2)

Then it should work.

Hello,

Does anyone knows if there is a Documentation or any wiki that
could help me to configure and build R
 using cygwin with the Intel Compilers on Windows?

Thanks,
Humberto.

No, cygwin is an unsupported platform.

Best,
