R: "ExpressionSet" data not loading -

i wanted convert dataframe of "array data" expressionset. followed link , managed same ( expressionset - phenodata ) .

so here expressionset

> test expressionset (storagemode: lockedenvironment) assaydata: 1000 features, 733 samples element names: exprs protocoldata: none phenodata samplenames: x8261 x8164 ... x7727 (733 total) varlabels: batch gender varmetadata: labeldescription featuredata: none experimentdata: utilize 'experimentdata(object)' annotation:

but load/use object/data inorder utilize particular r bundle "pvca" (http://www.bioconductor.org/packages/2.12/bioc/vignettes/pvca/inst/doc/pvca.pdf) , this:

> data(test) warning message: in data(test) : info set âtestâ not found

i warning "data not found". can help me know why this? , can load info , overcome ?

thanks in advance..

data function returns info set author of bundle has included in package. if goal save expressionset across r sessions (this not necessary utilize pvca, library(pvca) in same session in create expressionset) utilize

save(test, file="test.rda")

in 1 session and

load("test.rda")

in another.
