Re: [R] Displaying trailing zeroes
formatC(round(12.01), digits=1, format=f) -Christos -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Lucke, Joseph F Sent: Thursday, January 24, 2008 4:37 PM To: r-help@r-project.org Subject: [R] Displaying trailing zeroes round(12.01,1) will give the answer 12, not 12.0 or even 12. To make a table look nice, I need to display the trailing zero so that just as round(12.05,1) yields 12.1, round(12.01) yields 12.0. I cannot find an answer in print() or format() or options(). Any suggestions would be appreciated. Joseph F.

You aren't asking about the answer, you are asking about how to control how the number is printed. To make a table look nice, I need to display the trailing zero so that just as round(12.05,1) yields 12.1, round(12.01) yields 12.0. I cannot find an answer in print() or format() or options(). Any suggestions would be appreciated. R tries to be consistent when it prints a vector, so you could convert all the entries at once. For example, x - c(12, 12.1) format(x) [1] 12.0 12.1 If you want individual control on each entry, see formatC or sprintf. Christos gave you the formatC version; the sprintf version is sprintf(%.1f, 12) [1] 12.0 Duncan Murdoch Joseph F.
