Inserting missing seq number
Hallo Jeff Similar result you will get by na.locf function from zoo package df <- data.frame(seq = c(1,2,4,5,7), count = c(4,7,3,5,2)) vec <-data.frame(seq =1:7) df <- merge(vec, df, all=T) library(zoo) df$count <- na.locf(df$count) Cheers Petr

R-help Is there a R function that will insert missing sequence number(s) and then fill a missing observation with the preceding value. For example df <- data.frame(seq = c(1,2,4,5,7), count = c(4,7,3,5,2)) seq count 1 1 4 2 2 7 3 4 3 4 5 5 5 7 2 What I need is seq count 1 1 4 2 2 7 3 3 7 4 4 3 5 5 5 6 6 5 7 7 2 Jeff
