Inserting missing seq number
Hi Jeff, tidyr::fill() will do what you want aDf <- data.frame(seq=1:7) bDf <- left_join(aDf,df,by="seq") tidyr::fill(bDf,count) HTH, Eric On Wed, Mar 30, 2022 at 5:47 AM Jeff Reichman <reichmanj at sbcglobal.net> wrote:
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
