dot-getParam: Extract parameter value(s) from a parameter file
In MayaGueguen/RFate: Vegetation modelling with the FATE model

Description Usage Arguments Value Author(s) Examples

This function extracts from a text file the value(s) of a given parameter.

1	.getParam(params.lines, flag, flag.split, is.num = TRUE)

`params.lines`	a `string` corresponding to the name of the file from which to extract the parameter value
`flag`	a `string` corresponding to the parameter name to be extracted and that must be present into the `param.lines` file
`flag.split`	a `string` to choose the concerned type of parameter (either "" or "`^--.*--$`"), depending on the type of parameter file (containing values or filenames)
`is.num`	default `TRUE`. If `TRUE`, the extracted parameter is considered to be `numeric` and will be processed as such

A vector containing one or more values of type string (if is.num = FALSE) or numeric (if is.num = TRUE).
