flowjo_biexp_trans(..., n = 6, equal.space = FALSE)

flowJo_biexp_trans(...)

Arguments

...

parameters passed to flowJoTrans

n

desired number of breaks (the actual number will be different depending on the data range)

equal.space

whether breaks at equal-spaced intervals

Value

biexponential transformation object

Examples

library(flowCore) data(GvHD) fr <- GvHD[[1]] data.raw <- exprs(fr)[, "FL1-H"] trans.obj <- flowjo_biexp_trans(equal.space = TRUE) brks.func <- trans.obj[["breaks"]] brks <- brks.func(data.raw) brks # biexp space displayed at raw data scale

#transform it to verify it is equal-spaced at transformed scale trans.func <- trans.obj[["transform"]] print(trans.func(brks))
