get.geotop.inpts.keyword.value: Returns the values of a keyword of "geotop.inpts" file or data frame with the suitable format

Description

Returns the values of a keyword of "geotop.inpts" file or data frame with the suitable format

Usage

get.geotop.inpts.keyword.value(keyword,
    inpts.frame = NULL, vector_sep = NULL, numeric = FALSE,
    format = "%d/%m/%Y %H:%M", date = FALSE, tz = "A",
    raster = FALSE, file_extension = ".asc",
    add_wpath = FALSE, wpath = NULL,
    use.read.raster.from.url = TRUE, data.frame = FALSE,
    formatter = "%04d", level = 1, date_field = "Date",
    isNA = -9999, matlab.syntax = TRUE,
    projfile = "geotop.proj", ...)

Arguments

keyword

keyword name

inpts.frame

data frame returned by declared.geotop.inpts.keywords or NULL. Default is NULL.

vector_sep

character value for the separator chacter if Keyword Value must be returned as a vector, otherwise it is NULL. Default is NULL, but if numeric or date are FALSE, vactor_sep

numeric

logical value. If TRUE the Value has numeric type, otherwise it is a string or string vector. Default is FALSE.

date

logical value. If TRUE the Value is retured as POSIXlt date, otherwise it is a string or string vector. Default is FALSE.

format

string format representing the date, see as.POSIXlt, used if date is TRUE. Default is "%d/%m/%Y %H:%M" (which is the format used in geotop.inpts

tz

format string representing the time zone, see as.POSIXlt, used if date is TRUE. Default is "A".

raster

logical value. Default is FALSE. If TRUE function returns direclty the raster map as Raster-class object built with raster

file_extension

Extension to be added to the keyword if keyword is a file name. Default is ".asc"

wpath

working directory containing GEOtop files (included the inpts file), see declared.geotop.inpts.keywords. It is mandatory if raster is TRUE.

add_wpath

logical value. Default is FALSE. If TRUE, the wpath string is attached to the keyword string value. It is automatically set TRUE if raster is TRUE.

use.read.raster.from.url

logical value. Default is TRUE. If TRUE the RasterLayer are read with read.raster.from.url, istead of raster (oth

data.frame

logical value. It is an option for tabular data. If TRUE function returns direclty a data frame or a list of data frames as data.frame or zoo

formatter

string value. It is the decimal formatter contained in the file name and used in case the tabular data are referred at several points. Default is "%04d" . It is used in case data.frame is TRUE.

level

integer values. Numbers incating all the identandification numbers of the files containing the requested data frames. Default is 1, correspondig to the decimal formatter "0001". See examples.

date_field

string value. Default is "Date", otherwise defined by the value of HeaderDateDDMMYYYYhhmmMeteo geotop keyword. It is used only if the argument data.frame is TRUE. If it is NULL or NA

isNA

numeric value indicating NA in geotop ascii files. Default is -9999.00

matlab.syntax

logical value. Default is FALSE. If TRUE a vector is written in a string according to *.m file syntax. Warning: this synstax is not read by GEOtop.

projfile

fileneme of the GEOtop projection file. Default is geotop.proj.
