Generate a command-line representation of a configuration

buildCommandLine receives two vectors, one containing the values of the parameters, the other containing the switches of the parameters. It builds a string with the switches and the values that can be used as a command line to call the program to be tuned, thus generating one candidate configuration.

Usage

buildCommandLine(values, switches)

Arguments

values: A vector containing the value of each parameter for the candidate configuration.
switches: A vector containing the switches of each paramter (in an order that corresponds to the values vector).

Value

A string concatenating each element of switches and values for all parameters with a space between each pair of parameters (but none between the switches and the corresponding values).

Examples

switches <- c("--switch1 ", "--switch2-", "--switch3=")
values <- list("value_1", 1L, sqrt(2))
buildCommandLine (values, switches)
#> [1] "--switch1 value_1 --switch2-1 --switch3=1.4142135623731"
