library(GenomicDataCommons,quietly = TRUE)
I made a small change to the filtering expression approach based on
changes to lazy evaluation best practices. There is now no need to
~ in the filter expression. So:
q = files() %>% GenomicDataCommons::filter( cases.project.project_id == 'TCGA-COAD' & data_type == 'Aligned Reads' & experimental_strategy == 'RNA-Seq' & data_format == 'BAM')
And get a count of the results:
##  1183
And the manifest.
