Please consider using the slider package.
Tiling window without overlapping observations:
tile2()
and ptile()
always returns a list.
tile2_lgl()
, tile2_int()
, tile2_dbl()
, tile2_chr()
use the same
arguments as tile2()
, but return vectors of the corresponding type.
tile2_dfr()
tile2_dfc()
return data frames using row-binding & column-binding.
tile2(.x, .y, .f, ..., .size = 1, .bind = FALSE)tile2_dfr(.x, .y, .f, ..., .size = 1, .bind = FALSE, .id = NULL)
tile2_dfc(.x, .y, .f, ..., .size = 1, .bind = FALSE)
ptile(.l, .f, ..., .size = 1, .bind = FALSE)
ptile_dfr(.l, .f, ..., .size = 1, .bind = FALSE, .id = NULL)
ptile_dfc(.l, .f, ..., .size = 1, .bind = FALSE)
Objects to slide over simultaneously.
Objects to slide over simultaneously.
A function, formula, or vector (not necessarily atomic).
If a function, it is used as is.
If a formula, e.g. ~ .x + 2
, it is converted to a function. There
are three ways to refer to the arguments:
For a single argument function, use .
For a two argument function, use .x
and .y
For more arguments, use ..1
, ..2
, ..3
etc
This syntax allows you to create very compact anonymous functions.
If character vector, numeric vector, or list, it is
converted to an extractor function. Character vectors index by
name and numeric vectors index by position; use a list to index
by position and name at different levels. If a component is not
present, the value of .default
will be returned.
Additional arguments passed on to the mapped function.
An integer for window size. If positive, moving forward from left to right; if negative, moving backward (from right to left).
If .x
is a list, should .x
be combined before applying .f
?
If .x
is a list of data frames, row binding is carried out.
Either a string or NULL
. If a string, the output will contain
a variable with that name, storing either the name (if .x
is named) or
the index (if .x
is unnamed) of the input. If NULL
, the default, no
variable will be created.
Only applies to _dfr
variant.
A list of vectors, such as a data frame. The length of .l
determines the number of arguments that .f
will be called with. List
names will be used if present.
