Hi All, I'm using the subset function to select a list of variables, some of which are contiguous in the data frame, and others of which are not. It works fine when I use the form: subset(mydata,select=c(x1,x3:x5,x7) ) In reality, my list is far more complex. So I would like to store it in a variable to substitute in for c(x1,x3:x5,x7) but cannot get it to work. That use of the c function

This is 100% functionally equivalent to 3.54-pre1, with only a few minor documentation changes. Changes in 3.54: * Add "menu separator", "menu indent", "menu disabled" (see README.menu). * vesamenu: fix handing of VESA modes with noncontiguous memory buffers. In particular, Qemu/KVM sets up such a mode when Cirrus Logic emulation is enabled (which is the default.) * Support for calling real mode functions using far calls, with argument on the stack. This was implemented to support...

Is there any similar function in R to the first. in SAS? What it dose is: Lets say we have this table: a b c 1 1 5 1 0 2 2 0 2 2 0 NA 2 9 2 3 1 3 and then I want do to do one thing the first time the number 1 appers in a and something else the secund time 1 appers in a and so on. so something similar to: if first.a { a$d<-1 }else{ a$d<-0 } This would give me
