tidyselect implements a DSL for selecting variables. It provides helpers for selecting variables:
var1:var10
: variables lying between var1
on the left and var10
on the right.starts_with("a")
][tidyselect::starts_with]: names that start with "a"
.ends_with("z")
][tidyselect::ends_with]: names that end with "z"
.contains("b")
][tidyselect::contains]: names that contain "b"
.matches("x.y")
][tidyselect::matches]: names that match regular expression x.y
.num_range(x, 1:4)
][tidyselect::num_range]: names following the pattern, x1
, x2
, ..., x4
.all_of(vars)
][tidyselect::all_of]/[any_of(vars)
][tidyselect::any_of()]:
matches names stored in the character vector vars
. all_of(vars)
will
error if the variables aren't present; any_of(var)
will match just the
variables that exist.everything()
][tidyselect::everything]: all variables.last_col()
][tidyselect::last_col]: furthest column on the right.where(is.numeric)
][tidyselect::where]: all variables where
is.numeric()
returns TRUE
.As well as operators for combining those selections:
!selection
: only variables that don't match selection
.selection1 & selection2
: only variables included in both selection1
and selection2
.selection1 | selection2
: all variables that match either selection1
or selection2
.Any scripts or data that you put into this service are public.
