[R] Question on bioconductor: reading affymetrix data
Hi everyone, My purpose is to read a .CEL file into R. The .CEL file was created from a .CAB by using DTT software found on Affymetrix website I read the .CEL file in R using ReadAffy as follows: d2=ReadAffy(widget=T) and I complete the fields as required. It does not complain. For example I could find the description: description(d2) Experimenter name: BB Laboratory: FFL Contact information: Title: Heter URL: www.bioconductor.org A 1 word abstract is available. Use 'abstract' method. Information is available on: samples, preprocessing But if I want to see the values for MM I get an error: mm(d2)[1:2] Note: You did not specify a download type. Using a default value of: Win32 This will be fine for almost all users Error in if ((is.null(deps)) || (length(deps) == 0) || (deps == )) return(NULL) : missing value where TRUE/FALSE needed I appreciate any ideas you may have. Thank you.

[R] variance estimator for the cumulative incidence function
Hi everyone,
I am using the package cmprsk in R to estimate the cumulative incidence
function and its variance. In the manual it is mentioned that the variance
is calculated based on Dr. Aalen's paper (1978, Nonparametric estimation of
partial transition probabilities in multiple decrement models).
I would appreciate if someone could provide me with a source where the
variance is expressed in a more readable way, for example as a sum.
I appreciate your help.
Thank you.
