Mutate a PlySummarizedExperiment object under an data mask. Unlike a few other
dplyr implementations, all contextual evaluations of mutate() for
SummarizedExperiment are valid.
Examples
mutate(se_simple,
counts_1 = counts + 1,
logp_counts = log(counts_1),
# access assays context with ".assays" pronoun,
# note that assays are sliced into a list to
# fit dimensions of cols context
cols(sum = purrr::map_dbl(.assays$counts, sum)),
# access assays context "asis" with the same pronoun
# but with a "_asis" suffix.
rows(sum = rowSums(.assays_asis$counts))
)
