The ll() function of R.oo returns a data.frame with various attributes that you can subset on, e.g.
> subset(R.oo::ll(), data.class %in% c("zoo", "xts")) member data.class dimension objectSize 2 fz zoo 10 1344 4 sample.xts xts c(180,4) 10128 5 x zoo 5 528 6 x1 zoo 5 880 7 x2 zoo 5 496 9 y zoo 5 1040 11 z zoo c(5,3) 1184 12 z0 zoo 0 448 13 z2 zoo c(4,3) 904 14 z20 zoo c(4,0) 616 15 z3 zoo 8 528 16 z4 zoo 5 592 17 z5 zoo 5 792 Henrik On Sat, Jul 28, 2018, 08:22 Jeff Newmiller <jdnew...@dcn.davis.ca.us> wrote: > You can extract the names into a character vector with ls and then use > grep(..., values=TRUE ) to select which ones you want to remove, and then > pass that list to rm. > > However, due to the way R handles memory you are unlikely to see much > savings by doing this.
