wbt_conditional_evaluation {whitebox}

Conditional evaluation

Description

Performs a conditional evaluation (if-then-else) operation on a raster.

Usage

wbt_conditional_evaluation(
  input,
  output,
  statement = "",
  true = NULL,
  false = NULL,
  wd = NULL,
  verbose_mode = NULL,
  compress_rasters = NULL,
  command_only = FALSE
)

Arguments

input

Name of the input raster file.

output

Name of the output raster file.

statement

Conditional statement e.g. value > 35.0. This statement must be a valid Rust statement.

true

Value where condition evaluates TRUE (input raster or constant value).

false

Value where condition evaluates FALSE (input raster or constant value).

wd

Changes the working directory. Default: NULL will use the value in WhiteboxTools settings, see wbt_wd() for details.

verbose_mode

Sets verbose mode. If verbose mode is FALSE, tools will not print output messages. Default: NULL will use the value in WhiteboxTools settings, see wbt_verbose() for details.

compress_rasters

Sets the flag used by 'WhiteboxTools' to determine whether to use compression for output rasters. Default: NULL will use the value in WhiteboxTools settings, see wbt_compress_rasters() for details.

command_only

Return command that would be executed by system() rather than running tool. Default: FALSE.

Value

Returns the tool text outputs.
