subsetting with greater than and less than indexing
Hi Arun, thank-you for your assistance. I'm sorry that I did not provide a reproducible example. I will provide a reproducible example the next time. Using the next to last line of your code I was able to get what I needed without using the for loop. Thanks again.

"Cut marks" on a plot's y-axis to indicate it is a truncated axis
Hi, I've plotted a Kaplan-Meier curve but the curves only range from 0.7 to 1 on the y-axis. Therefore I have used: - ylim=c(0.7,1) [although I think convention dictates that you plot 0.5 to 1 to show the median? A few papers I've read have done this]?? BUT, I would like a symbol like // (but rotated 90 degrees) to indicate that the y-axis has been truncated. I'd need to be able to

zeros in double matrix rather than character matrix
Hi, how are you? I have 1000 total columns with 100 rows and I have shown 4 columns of 100 rows below. I want the zeros to be read in as numerical or integer values rather than a character. Right now I have a 100x0 character matrix rather than a 100x1000 double matrix. What do I need to do to read in a .csv spreadsheet with counting the zeros as a numerical or integer value? Thank-you.
