replacePAR: Replaces a namelist or a parameter
In Maeswrap: Wrapper Functions for MAESTRA/MAESPA

Description Usage Arguments Value Author(s) See Also Examples

The function replaceNameList replaces the whole namelist in an input file. All parameters in the namelist must be provided, otherwise MAESTRA/MAESPA will likely crash. Or, you can use replacePAR to replace a single parameter. If the new parameter value(s) is a vector (or a single value), the values #' will be placed on a single line in the parameter file. If instead a matrix is provided, each row of the matrix is placed on a separate line.

WARNING : The input file is modified. Make sure to backup your original input files!

replaceNameList(namelist, datfile, vals)

replacePAR(datfile, parname, namelist, newval, noquotes = TRUE)

`namelist`	Name of the namelist.
`datfile`	Name of the input file.
`vals`	A list of values (see example below).
`parname`	Name of the parameter to replace the value of.
`newval`	New value of the parameter. Can be a single value or a vector, or a matrix (see Details).
`noquotes`	Logical. If FALSE, does print quotes around character values.

Nothing is returned. The input file is modified.
