search for: timelag

Dear r-help, I'm having this DF df <- data.frame(id = 1:6, xout = c(1234, 2134, 234, 456, 324, 345), xin= c(NA, 34,67,87,34, NA)) and would like to calculate the fraction (xin_t / xout_t-1) The result should be: # NA, 2.76, 3.14, 37.18, 7.46, NA I am sure there is a solution using zoo... but I don't know how... Thanks for any help! Patrick

...ng. As you may know, Debian's policies involve a two-week waiting period, and a lack of critical bugs reported, for a package to make it into testing. So there's a certain innate lag in what you see in testing. If you're a user of testing, it's because you like that tradeoff between timelag and stability. The Debian packages get updated automatically when one does # apt-get update && apt-get dist-upgrade from time to time. The stuff you get using install.packages() doesn't. A few weeks ago I had asked Dirk how one might automate the removal of packages that I put in, u...
