Hi
I'm running the latest R on a presumably up to date Linux server.
'Doing something silly I'm sure, but can't see why my saved PLMset objects
come out all wrong. To use an example:
Setting up an example PLMset (I have the same problem no matter what example
I use)
> library(affyPLM)
> data(Dilution) # affybatch object
> Dilution = updateObject(Dilution)
> options(width=36)
> expr <- fitPLM(Dilution)
This works, and I'm able to get the probeset coefficients with coefs(expr).
until I save and try reloading:
> save(expr, file="expr.RData")
> rm(expr) # just to be sure
> expr <- load(expr.RData)
Now, running coefs(expr) says:
> Error in function (classes, fdef, mtable) : unable to find an inherited
method for function "coefs", for signature "character"
Trying str(exp) just gives the following:
> chr "exp"
expr.Rdata appears to save properly (in that there is an actual file with
notable size in my working directory).
Thanks in advance,
Quin
