check_installed() fails if packages are not installed

Code
  check_installed("rlangFoo")
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The package "rlangFoo" is required.
Code
  check_installed(c("rlangFoo", "rlangBar"))
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The packages "rlangFoo" and "rlangBar" are required.
Code
  check_installed(c("rlangFoo", "rlangBar"), "to proceed.")
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The packages "rlangFoo" and "rlangBar" are required to proceed.

is_installed() checks minimal versions

Code
  is_installed(c("rlang", "testthat"), version = "0.1")
Condition <rlang_error>
  Error in `is_installed()`:
  ! `version` must be `NULL` or a vector of versions the same length as `pkg`.

check_installed() checks minimal versions

Code
  check_installed(c("rlang", "testthat"), version = "0.1")
Condition <rlang_error>
  Error in `check_installed()`:
  ! `version` must be `NULL` or a vector of versions the same length as `pkg`.
Code
  check_installed("rlangFoo", version = "1.0")
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The package "rlangFoo" (>= 1.0) is required.
Code
  check_installed(c("rlangFoo", "rlangBar"), version = c("1.0", NA))
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The packages "rlangFoo" (>= 1.0) and "rlangBar" are required.
Code
  check_installed(c("rlangFoo", "rlangBar"), version = c(NA, "2.0"))
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The packages "rlangFoo" and "rlangBar" (>= 2.0) are required.
Code
  check_installed(c("rlangFoo", "rlangBar"), "to proceed.", version = c("1.0",
    "2.0"))
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The packages "rlangFoo" (>= 1.0) and "rlangBar" (>= 2.0) are required to proceed.
Code
  check_installed(c("rlangFoo (>= 1.0)", "rlangBar (> 2.0)"), "to proceed.")
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The packages "rlangFoo" (>= 1.0) and "rlangBar" (> 2.0) are required to proceed.

< requirements can't be recovered with restart

Code
  check_installed("rlang (< 0.1)")
Condition <rlib_error_package_not_found>
  Error in `foo()`:
  ! The package "rlang" (< 0.1) is required.

pkg is type-checked

Code
  is_installed(1)
Condition <rlang_error>
  Error in `is_installed()`:
  ! `pkg` must be a package name or a vector of package names.
Code
  is_installed(na_chr)
Condition <rlang_error>
  Error in `is_installed()`:
  ! `pkg` must be a package name or a vector of package names.
Code
  check_installed(c("foo", ""))
Condition <rlang_error>
  Error in `check_installed()`:
  ! `pkg` must be a package name or a vector of package names.
Code
  check_installed(c("foo", "bar"), version = c("1", ""))
Condition <rlang_error>
  Error in `check_installed()`:
  ! `version` must be `NULL` or a vector of versions the same length as `pkg`.

pkg_version_info() parses info

Code
  pkg_version_info("foo (1.0)")
Condition <rlang_error>
  Error in `caller()`:
  ! Can't parse version in `pkg`.
  x Problematic versions:
  * foo (1.0)
  i Example of expected version format: `rlang (>= 1.0.0)`.
Code
  pkg_version_info("foo (>= 1.0)", "1.0")
Condition <rlang_error>
  Error in `caller()`:
  ! Can't supply version in both `pkg` and `version`.
  x Redundant versions:
  * "foo (>= 1.0)"
Code
  pkg_version_info(c("foo (!= 1.0)"))
Condition <rlang_error>
  Error in `caller()`:
  ! `compare` must be one of ">", ">=", "==" ,"<", or "<=".

pkg_version_info() supports cmp

Code
  pkg_version_info(c("foo", "bar", "baz"), NULL, c(NA, NA, ">="))
Condition <rlang_error>
  Error in `caller()`:
  ! `version` must be supplied when `compare` is supplied.
Code
  pkg_version_info(c("foo", "bar", "baz"), c("1", "2", NA), c(NA, NA, ">="))
Condition <rlang_error>
  Error in `caller()`:
  ! `version` must be supplied when `compare` is supplied.
Code
  pkg_version_info(c("foo", "bar (>= 2.0)"), c(NA, "2.0"), c(NA, ">="))
Condition <rlang_error>
  Error in `caller()`:
  ! Can't supply version in both `pkg` and `version`.
  x Redundant versions:
  * "bar (>= 2.0)"
Code
  pkg_version_info("foo", "1.0", "!=")
Condition <rlang_error>
  Error in `caller()`:
  ! `compare` must be one of ">", ">=", "==" ,"<", or "<=".
Code
  pkg_version_info("bar (== 1.0)", "1.0", "==")
Condition <rlang_error>
  Error in `caller()`:
  ! Can't supply version in both `pkg` and `version`.
  x Redundant versions:
  * "bar (== 1.0)"

action is checked

Code
  check_installed("foo", action = "identity")
Condition <rlang_error>
  Error in `check_installed()`:
  ! `action` must be an R function or `NULL`, not the string "identity".
Code
  check_installed("foo", action = identity)
Condition <rlang_error>
  Error in `check_installed()`:
  ! `action` must take a `...` argument.

check_installed() works within tryCatch(error = ) (#1402, tidyverse/ggplot2#4845)

Code
  cat(tryCatch(error = function(cnd) NULL, check_installed("rlangFoo")))
Output
  i The package "rlangFoo" is required.
  x Would you like to install it?
