Hi Thomas I try it, but the graphic make is not a point graphic, is a ?scale? plot, like this: |_ | |_ | | | |__ | |_ | |_ |_____________ I need the same graphic, but with point like this: | | * | * | * | * | * |____________ I try to change the type (plot(survfit(Surv(tempo,censor)~trat),type="p")), but dont work:(((. I try to use points(survfit(Surv(tempo,censor)~trat), but this only work over the plot graphics with ?scales lines? I try to plot using type="n" but dont work too. Whem I use type the error appear: Error in plot.default(tempx, tempy * yscale, type = "n", log = logax, : formal argument "type" matched by multiple actual arguments Exist a mode for save the data to be plotted, saving all points calculated by the function survfit(Surv(tempo,censor)~trat in a object? Thanks for all Inte mais Ronaldo
