version = "1.0.0", dry.run = FALSE)
nmt## A MultiAssayExperiment object of 6 listed
## experiments with user-defined names and respective classes.
## Containing an ExperimentList class object of length 6:
## [1] acc_DHS: matrix with 290 rows and 826 columns
## [2] met_DHS: matrix with 66 rows and 826 columns
## [3] acc_cgi: matrix with 4459 rows and 826 columns
## [4] met_cgi: matrix with 5536 rows and 826 columns
## [5] acc_genebody: matrix with 17139 rows and 826 columns
## [6] met_genebody: matrix with 15837 rows and 826 columns
## Functionality:
## experiments() - obtain the ExperimentList instance
## colData() - the primary/phenotype DataFrame
## sampleMap() - the sample coordination DataFrame
## `$`, `[`, `[[` - extract colData columns, subset, or experiment
## *Format() - convert into a long or wide DataFrame
## assays() - convert ExperimentList to a SimpleList of matrices
## exportClass() - save all data to filesCheck row annotations:
