Hi, I have probably basic question, but I would be happy if somebody could help me with this: I have a dataframe where I want to assign a value to other column copying the value in previous row under some condition. Here is an example (dput on the end of message):> test[278:290,]datetime state state_bef state_new 279 2011-11-12 08:24:57 a 0 a 280 2011-11-12 08:31:42 b a b 281 2011-11-13 00:00:00 0 b b 282 2011-11-14 00:00:00 0 0 b 283 2011-11-15 00:00:00 0 0 0 284 2011-11-16 00:00:00 0 0 0 285 2011-11-17 00:00:00 0 0 0 286 2011-11-18 00:00:00 0 0 0 287 2011-11-19 00:00:00 0 0 0 288 2011-11-19 06:13:18 a 0 a 289 2011-11-19 06:40:06 b a b 290 2011-11-19 08:56:54 a b a 291 2011-11-19 09:19:39 b a b What I need is: if state != "0", the state_new==state if state == "0" & state_bef!="0", the state_new==state_bef if state == "0" & state_bef=="0", the state_new==state_bef of the previous row. The idea is when there is "00:00:00" in datetime, I need to repeat the last "state" value in the "state_new" I have tried various ifelse conditions and loops, the last is this, which doesn't work for all rows: test$state_new[test$state!="0"] <- test$state[test$state!="0"] test$state_new[test$state=="0" & test$state_bef!="0"] <- test$state_bef[test$state=="0" & test$state_bef!="0"] test$state_new[test$state=="0" & test$state_bef=="0"] <- test$state_new[test$state=="0" & test$state_bef=="0"] # doesn't work for all rows... This should be the result datetime state state_bef state_new 279 2011-11-12 08:24:57 a 0 a 280 2011-11-12 08:31:42 b a b 281 2011-11-13 00:00:00 0 b b 282 2011-11-14 00:00:00 0 0 b 283 2011-11-15 00:00:00 0 0 b 284 2011-11-16 00:00:00 0 0 b 285 2011-11-17 00:00:00 0 0 b 286 2011-11-18 00:00:00 0 0 b 287 2011-11-19 00:00:00 0 0 b 288 2011-11-19 06:13:18 a 0 a 289 2011-11-19 06:40:06 b a b 290 2011-11-19 08:56:54 a b a 291 2011-11-19 09:19:39 b a b In the dataframe I send as an example there is just one block of this repeated "0" values, but within real dataframe there are more blocks like that. Thanks for any ideas!

Hi Zuzana,>From your description it seems that you want to repeat the last"state_new" value when there are repeated zeros in both "state" and "state_bef". If that is the case, you may need to step through the data frame like this: for(drow in 1:(dim(test)[1])) { if(test$state[drow] != 0) test$state_new[drow]<-test$state[drow] else { if(test$state_bef[drow] != 0) test$state_new[drow]<-test$state_bef[drow] else test$state_new[drow]<-test$state_new[drow-1] } } This assumes that "state" and "state_bef" will never both be zero in the first row. If this might happen, you will have to add a "memory" variable (e.g. "state_last"), initialize it to whatever value you want and then set it equal to "state_new" at the end of each step. It may be possible to do this as you were attempting above using something like "rle", but I think it will be difficult.

Hi Jim, your code works just perfectly, it is exactly what I was looking for, thank you very much!!! I'm glad to learn something new, I haven't seen the use of "drow in 1:(dim(all)[1])" before. I made the code a bit shorter, excluding the use of "stat_bef" column, which I created just for my intents with loops. # simplified version without "state_bef" for(drow in 1:(dim(test)[1])) { if(test$state[drow] != "0") test$state_new[drow]<-test$state[drow] else { test$state_new[drow]<-test$state_new[drow-1] } } Best wishes, Zuzana On 21 January 2015 at 00:20, Jim Lemon <drjimlemon at gmail.com> wrote:> Hi Zuzana, > From your description it seems that you want to repeat the last > "state_new" value when there are repeated zeros in both "state" and > "state_bef".

Hi I am not sure if I catch it correctly but from your example state has preference over state new except in the case where state is 0. I would change state_bef 0 to NA and use na.locf function from zoo package. test$state_bef[test$state_bef=="0"] <- NA test$state_bef <- na.locf(test$state_bef, na.rm=FALSE) test$state_new <- ifelse(test$state == "0", as.character(test$state_bef), as.character(test$state)) library(zoo) # as you failed to use dput for data I need to do some transformation before I got appropriate object. temp<-read.delim("clipboard", header=F, sep=" ") temp<-t(temp) temp<-t(temp[complete.cases(temp),]) temp<-data.frame(temp) names(temp)[4:6]<-c("state", "state_bef", "state_new") # here is the code temp$state_bef[temp$state_bef=="0"] <- NA temp$state_bef <- na.locf(temp$state_bef, na.rm=FALSE) temp$state_new <- ifelse(temp$state == "0", as.character(temp$state_bef), as.character(temp$state)) temp V1 V2 V3 state state_bef state_new 1 279 2011-11-12 08:24:57 a <NA> a 2 280 2011-11-12 08:31:42 b a b 3 281 2011-11-13 00:00:00 0 b b 4 282 2011-11-14 00:00:00 0 b b 5 283 2011-11-15 00:00:00 0 b b 6 284 2011-11-16 00:00:00 0 b b 7 285 2011-11-17 00:00:00 0 b b 8 286 2011-11-18 00:00:00 0 b b 9 287 2011-11-19 00:00:00 0 b b 10 288 2011-11-19 06:13:18 a b a 11 289 2011-11-19 06:40:06 b a b 12 290 2011-11-19 08:56:54 a b a 13 291 2011-11-19 09:19:39 b a b>which results in desired solution.
