Extract a simple ensemble out of a repeat ensemble

Source: R/get_repeat.R
get_repeat.Rd

This function extracts a simple ensemble out of a repeat ensemble, by index or by name.

Usage

get_repeat(x, i)

Arguments

x

a repeat ensemble object

i

index of the simple ensemble to extract, or name of the simple ensemble to extract.

Value

a simple ensemble object

Details

Note that, when using a numerical index, that index refers to the order of the repeats for which at least one algorithm passed the appropriate thresholds set when creating the ensemble. For example, if "rep_02" had not good algorithms, the repeat ensemble would only contain labels "rep_01", "rep_03", etc. So, index 2 would refer to "rep_03" in this case. If you want to be sure to get a given repeat, it is safer to use the name of the repeat (e.g. "rep_03") rather than the index.
