Just realized my answer yesterday went to Francesco and not the list: Since it sounds like you have two matrices of the same dimensions, why not represent these as two assays in a SummarizedExperiment? E.g.:
> statvals <- matrix(rnorm(100), ncol=5) > pvals <- pnorm(statvals) > library(SummarizedExperiment) > se <- SummarizedExperiment(list(statvals = statvals, pvals = pvals)) > se class: SummarizedExperiment dim: 20 5 metadata(0): assays(2): statvals pvals rownames: NULL rowData names(0): colnames: NULL colData names(0): > If you then have more than one of these, with different dimensions, then MultiAssayExperiment would be of use to you. (PS: this question is probably better suited for support.bioconductor.org) On Oct 23, 2017 4:50 PM, "Vincent Carey" <st...@channing.harvard.edu> wrote: > no answers yet? would it work to put your matrices as separate assays in a > SummarizedExperiment? > as long as they are conformant in dimensions and dimnames I think that > would work.
