Replace parameter value(s) from a parameter file

Source: R/UTILS.setParam.R

This function finds in a text file the value(s) of a given parameter, and replace it with new value(s).

.setParam(params.lines, flag, flag.split, value)

Arguments

params.lines

a string corresponding to the name of the file from which to replace 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)

value

a string or a numeric value (it can also be a vector) containing the new value of the parameter to be changed
