It is not an anomaly. The object is the same size
(object.size(f1)==object.size(f2)); its file representation is different.

Dear R-helpers,
Please have a look at the following. f1 is the same as f2 except that it has
some values replaced by NA. But it's corresponding file is slightly bigger
than the file containing f2. Could someone please tell me if this is an
anomaly ?
load("file1")
ls()
[1] "f1"
load("file2")
ls()
[1] "f1" "f2"
dput(f1)
structure(c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, NA, NA, NA, 2, 2,
2, NA, NA, NA, NA), .Dim = c(10L, 2L), .Dimnames = list(NULL,
c("v1", "l1")), index = 1:10, class = "zoo")
dput(f2)
structure(c(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 2, 2, 2, 2, 2, 2,
2, 2, 2, 2), .Dim = c(10L, 2L), .Dimnames = list(NULL, c("v1",
"l1")), index = 1:10, class = "zoo")
