title: Plotting Kaplan-Meier survival curve with only one stratum having confidence interval
body: <p>I'm plotting a few Kaplan-Meier plots using R with two strata each for my analysis, and my PI would like the plots to have only one of the strata to have confidence intervals plotted. I've looked at various Kaplan-Meier survival curve plotting functions, but there don't seem to be any functions that allow only a subset of confidence intervals to be displayed. </p>
  
  <p>Are there any R packages with plotting functions that allow me to do this?</p>
