info.dimensions.lsd {LSDinterface}

Dimension information for a LSD results file

Description

This function reads some dimension information from a LSD results file (.res): number of time steps, number of variables and the original column (variable) names.

Usage

info.dimensions.lsd( file )

Arguments

file

the name of the LSD results file which the data are to be read from. If it does not contain an absolute path, the file name is relative to the current working directory, getwd(). Tilde-expansion is performed where supported. This can be a compressed file (see file) and must include the appropriated extension (usually .res or .res.gz).

Details

The returned number of time steps does not include the initial value (t = 0) for lagged variables (the second line of a .res format file).

Value

Returns a list containing two integer values and a character vector describing the selected results file.

tSteps

Number of time steps in file

nVars

Number of variables (including duplicated instances) in file

varNames

Names of variables (including duplicated instances) in file, after R name conversion
