Slice a PlySummarizedExperiment

slice() selects rows and/or columns by position.

Usage

# S3 method for class 'PlySummarizedExperiment'
slice(.data, ..., .preserve = FALSE)

Arguments

.data: a PlySummarizedExperiment object
...: expressions that resolve to integer values to slice, .data by. Note that only the rows() and cols() contexts are available here.
.preserve: Logical value. When FALSE, the default, group combinations are recomputed based on the resulting data. When TRUE, group combinations are retained, despite any groups being empty.

Examples

gse <- group_by(se_simple, rows(direction), cols(condition))
sgse <- slice(gse, rows(which(direction == "-")))
#> Error in h(simpleError(msg, call)): error in evaluating the argument 'x' in selecting a method for function 'slice': Rle of type 'S4' is not supported
