verifyFileStructure: Verify File Structure

Description

Ensures that the necessary files are present for other functions to work properly.

Usage

verifyFileStructure(
  path = "./",
  returnFileNames = TRUE,
  includeSolRad = TRUE,
  rasterExt = ".tif"
)

Value

Prints messages to the console if problems are found. If returnFileNames == TRUE, then a vector of filenames is returned.

Arguments

path: path to directory of rasters
returnFileNames: logical, should file paths and names be returned
includeSolRad: logical, should solar radiation files be required?
rasterExt: file extension of rasters

Details

This function searches for the following in the directory specified by path:

12 precipitation rasters

12 min temperature rasters

12 max temperature rasters

12 mean temperature rasters [optional]

12 solar radiation rasters

The naming scheme will be checked against the one defined via the custom naming environment. See link{?assignNames} for additional details.

An equivalent function for checking the names of rasters in R can be found at verifyRasterNames.

If mean temperature rasters are not detected, the raster creation functions will create mean temperature by taking the mean of the min and max.

Examples

Run this code

rasterPath <- system.file('extdata', package='envirem')
list.files(rasterPath)

# Assign naming scheme
assignNames(precip = 'prec_##')
varnames()

# As there are no problems with these files, the list of files 
# will be returned.
verifyFileStructure(rasterPath)

assignNames(reset = TRUE)
