Sync (expand or compress) a vector
sync_vector(
x,
newLength,
sep = " ",
fill = TRUE,
compressFun = NULL,
expandFun = NULL,
compressFunPart = NULL,
silent = rock::opts$get("silent")
)
The synced vector
The vector
The new length
When not specifying compressFun
and compressFunPart
, the
paste
function is used to combine elements, and in that case, sep
is
passed to paste
as separator.
When expanding streams, whether to duplicate elements to fill
the resulting vector. Ignored if fillFun
is specified.
If specified, when compressing streams, instead of pasting
elements together using separator sep
, the vectors are passed to function
compressFun
, which must accept a vector (to compress) and a single integer
(with the desired resulting length of the vector).
If specified, when expanding streams, instead of potentially
filling the new larger vector with elements (if fill
is TRUE
), the
vectors are passed to function expandFun
, which must accept a vector (to
compress) and a single integer (with the desired resulting length of
the vector).
A function to apply to the segments that are
automatically created; this can be passed instead of compressFun
.
Whether to be silent or chatty.
