1 2	project_sel(dat, g, x_vars, time_var = "time", status_var = "status", method = "L1", p0 = 5, nv_max = 40, save_file, ...)

`g`	additional data frame for bootstrapping
`x_vars`	vars to analysis
`time_var`	defults to time
`status_var`	defaults to status
`p0`	prior guess for the number of relevant variables
`save_file`	should results be saved on file
`d_train`	dataframe
`ncores`	for parallel.
`alpha`	alpha for elastic net
`relaxed`	apply relaxed lasso set to TRUE
