[R] error message when plotting survival curves
I am trying to plot survival curves using the following code as an example: rs1799964.coxph-(coxph(Surv(sassurvmonths,status)~age+stage+rs1799964_TNFA,method=efron)) plot(rs1799964.coxph,lyt=c(1,3),xlab=Survival in Months,ylab=Proportion Surviving) I am gettingthe following error message: Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ Any input to debugging this matter would be greatly appreciated. Thank you in advance. -Alison -- View this message in context: http://www.nabble.com/error-message-when-plotting-survival-curves-tp20075771p20075771.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] error message when plotting survival curves
I believe that you have to specify which variable is the x and also the y. I am not familiar with what you are doing, but it looks as though you need to specify both x and y to get it to plot.

You probably want plot(survfit(rs1799965.copxh)) -thomas I am gettingthe following error message: Error in xy.coords(x, y, xlabel, ylabel, log) : 'x' and 'y' lengths differ Any input to debugging this matter would be greatly appreciated.
