...for s < t, we know n_s - n_t samples exist in the interval [s, t). If this sample size of the difference is small I want to exclude the interval [10,s). This can be done comparing adjacent preceding rows using the following. > df0$itagA <- ifelse(c(10, diff(nsamA)) <= 4, 1, 0) >df0$itagB <- ifelse(c(10, diff(nsamB)) <= 4, 1, 0) >df0 ># Subset df0 on the tag results > df1 <- df0[df0$itagA != 1 & df0$itagB != 1,] > df1 This works fine, but here is my problem. This simply looks at only the immediate preceding row and not at rows further "down the line&qu...
