check_Miller1998_CONUSSoil: Check that CONUSSoil soil data are locally available

In DrylandEcology/rSW2exter: Access External Data as Input for SOILWAT2 and STEPWAT2 Simulations

Check that CONUSSoil soil data are locally available

Description

Check that CONUSSoil soil data are locally available

Usage

check_Miller1998_CONUSSoil(
  path = ".",
  vars = c("rockdepm", "rockvol", "bd", "sand", "clay", "silt"),
  lower_limits_by_vars = c(rockdepm = 0, rockvol = 0, bd = 30, sand = 0, clay = 0, silt =
    0)
)

Arguments

path	A character string. The path to the local copy of the CONUSSoil folder hierarchy, e.g., dirname(prepare_script_for_Miller1998_CONUSSoil()).
vars	A vector of character strings. The requested variables as used by CONUSSoil; see Miller et al. 1998.
lower_limits_by_vars	A named numeric vector. The names correspond to vars and values represent the lower limits that are conditioned/ masked out, i.e., set to NA.

Value

A logical vector of the length of vars.

Examples

script_to_download_conussoil <- prepare_script_for_Miller1998_CONUSSoil()

## Execute script to download data
## (or set `path_conussoil` to your local copy)
path_conussoil <- dirname(script_to_download_conussoil)

## Mask out unrealistic variable values
has_CONUSSoil_cond <- create_conditioned_Miller1998_CONUSSoil(
  path = path_conussoil
)

## Check that we have CONUSSoil data
has_CONUSSoil <- check_Miller1998_CONUSSoil(path = path_conussoil)

# Do we have all files?
isTRUE(all(has_CONUSSoil))

# If not, then examine which variables are missing
has_CONUSSoil
