eLTTB_aggregator {shinyHugePlot}

Aggregation using local minimum and maximum values, and Largest Triangle Three Buckets (LTTB) method.

Description

Efficient version off LTTB by first reducing really large data with the min_max_ovlp_aggregator and then further aggregating the reduced result with LTTB_aggregator.

Format

An R6::R6Class object

Super class

shinyHugePlot::aggregator -> eLTTB_aggregator

Public fields

LTTB

An R6 LTTB_aggregator instance

minmax

An R6 min_max_ovlp_aggregator instance

  accepted_datatype = c("numeric", "integer", "character", "factor", "logical")
)

Arguments

...

Arguments pass to the constructor of aggregator, LTTB_aggregator and min_max_oblp_aggregator objects.

interleave_gaps, coef_gap, NA_position, accepted_datatype

Arguments pass to the constructor of aggregator object.

Method clone()

Examples

data(noise_fluct)
agg <- eLTTB_aggregator$new(interleave_gaps = TRUE)
d_agg <- agg$aggregate(noise_fluct$time, noise_fluct$f500, 1000)
plotly::plot_ly(x = d_agg$x, y = d_agg$y, type = "scatter", mode = "lines")
