check.input: Check whether the input fulfills our requirements

In theGreatWhiteShark/climexUI: Shiny-based User Interface to Analyse Large Amounts of Station Data Using The Climex Package

Description

The time series has to be provided as a named list of named lists of class xts or data.frame objects. The position data has to be a data.frame containing at least the named columns name, longitude, and latitude or a SpatialPointsDataFrame containing a name column in their data slot.

Usage

check.input(list.data.sources, data.frame.positions, silent = FALSE)

Arguments

list.data.sources	A named list of named lists of xts-class time series or data.frames. The first level of hierarchy in the list corresponds to the different climatological variables, which will be accessible via the first drop down menu in the sidebar. The second level corresponds to the names of the individual stations measurements of the top level variable are available for. The series themselves can be provided either as a xts object to data.frame containing a numerical value and a time-date date column.
data.frame.positions	Either a data.frame containing at least the named columns name, longitude, and latitude or a SpatialPointsDataFrame containing a name column in its @data slot.
silent	Whether to display warnings if the check failed. Default = FALSE.

Details

All named elements of codelist.data.sources, which do not appear in the name column of data.frame.positions will be discarded and vice versa.

Internally the data.frame-type of list.data.sources will be converted into the xts type and the SpatialPointsDataFrame type of data.frame.positions will be converted into its data.frame equivalent.

Value

A list containing the result of the check (TRUE if the input has the right format) and a version of the input stripped of any list elements and data.frame columns, which just appear in one of the input arguments.

• check.result: Boolean

• list.data.sources: Same format as input

• data.frame.positions: Same format as input
