plot.predict.survivalFS: Survival and Cumulative Hazard Function Plot
In logicFS: Identification of SNP Interactions

Plots predicted survival or cumulative hazard curves of new observations for an object of class predict.survivalFS.

## S3 method for class 'predict.survivalFS'
plot(x, select_obs, xlab = "time", ylab = NULL, 
              ylim = NULL, type = "l", main = NULL, sub = NULL, 
              vec_col = NULL, vec_lty = NULL, addLegend = TRUE, ...)

`x`	an object of class `predict.survivalFS` as generated by the function `predict.logicBagg`.
`select_obs`	a numeric vector identifying the observations whose survival curves should be plotted. If `is.missing(select.obs)` the first five observations, or, if the number of observations is less than five, all observations are chosen.
`xlab`	a title for the x axis: see `title`.
`ylab`	a title for the y axis: see `title`. If `NULL`, the title is generated automatically.
`ylim`	a numeric vector of length 2 that sets the limits of the y axis. If `NULL`, the limits are generated automatically.
`type`	character indicating the type of plotting; actually any of the types as in `plot.default`.
`main`	an overall title for the plot: see `title`. If `NULL`, the main title is generated automatically.
`sub`	a sub title for the plot: see `title`. If `NULL`, the sub title is generated automatically.
`vec_col`	a numeric or character vector that specifies the plotting colors of the survival curves (see `par`). Vector must have the same length as `select_obs`.
`vec_lty`	a numeric or character vector that specifies the line types of the survival curves (see `par`). Vector must have the same length as `select_obs`.
`addLegend`	should a legend be added to the plot automatically?
`...`	Ignored.
