Hi, when ploting Kaplan-Meier estimate curves as below, the censoring
symbols
(crosses) to not change thickness along the lines 
plot(survfit(surv ~ I(x>=cut.off) ),lty=c(1,2), lwd=2)

is there any strightforward way to make it happen? thanks

 The symbols on the plot are characters, and are controled by the cex
parameter.  I don't know how to make a character "thicker" but not
larger, other than choosing a different font.  That would affect the
labels also, however.
