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 robert -- View this message in context: http://r.789695.n4.nabble.com/censoring-symbols-on-survfit-plot-tp3311283p3311283.html Sent from the R help mailing list archive at Nabble.com.

...t; which correspond to my starting point in time domain. Now I need to produce series over, 5 sec epochs up to end point, say: [1] "2008-04-12" [1] "23:00:00" So something like 2008-04-11 22:00:00 2008-04-11 22:00:05 2008-04-11 22:00:10 . . . 2008-04-12 23:00:00 Is there any strightforward way to do it? Any suggestions? Best, robert -- View this message in context: http://r.789695.n4.nabble.com/date-and-time-tp3905358p3905358.html Sent from the R help mailing list archive at Nabble.com.

Hello, A nice guy call Jun Shen was helping me out with this, but I require a bit more help. Below is my data set or list called 'test'. I'm trying to calculate the %RSD for each pair of index and keep it in cronological order if you can imagine a 3rd column with 'date' beside index. Result Index 1 0.2901 17 2 0.2928 17 3 0.2913 18 4 0.2893 18 5

In R, How to read Excel file and access the data item? Thank you. --------------------------------- [[alternative HTML version deleted]]

I have been searching for the R manual, unable to solve my problem. Questions 1) How can I put the x axis at the top of the plot? 2) I am plotting data from a CTD. I want to add series sal, obs and fluo at the same plot by using points(sal,deepth) ets. The data have different values so I want to use multiple x axis (4) with different scaling. How can I do that?

Hi All, I have checked everything I could find abot graphics, but still cannot solve the problem. Are there any ways to make a graph that plots two lines and two different y-axes, each of them has a scale that is related to the respective line. For example, y1 has a range 1:50 and y1 ranges 0:1. The x-axe is the same for both. Thank you in advance. --- Gregor Gawron

Hi all; I need to put 12 different plot2 into the same matrix. So my array for the matrix will be par(mfrow=c(3,4)). I am running ggplot2 to produce my 12 plots. For some reason, par(mfrow=c(3,4)) did not turn out 3*4 matrix. my basic R codes for each plot is par(mfrow=c(3,4)) library(ggplot2) p <- ggplot(a, aes(x=Genotypes, y=Plant_hight, size=Plant_hight, color=Showing_rate)) + . .
