i am dealing with ~700 450k arrays

they are derived from one study, so it makes sense to think of

them holistically.

both the load time and the memory consumption are not satisfactory.

has anyone worked on an object type that implements the rangedSE API but has

the assay data out of memory?

> unix.time(load("wbmse.rda"))

   user  system elapsed

 30.131   2.396  61.036

> object.size(wbmse)

124031032 bytes

> dim(wbmse)

[1] 485577    690

> object.size(assays(wbmse))

2680430992 bytes
