Re: [R] Please help(urgent) - How to simulate transactional data for reliability/survival analysis

A small example data set that illustrates your question will be of great value to those trying to help. This appears to be a transformation that you are wanting to do (timestamp to units of time) so a data representing what you have (dput() is handy for this) and one representing what you want

Re: [R] about adding a column for water year

Hi lily, It might be easier doing it like this: DF<-data.frame(year=rep(1972:1985,each=12), month=rep(1:12,14),day=rep(1,168)) DF$time<-paste(DF$year,DF$month,DF$day,sep="-") DF$flow<-runif(168,4,7) DF$wyear<-DF$year + (DF$month > 9) Jim On Wed, Jul 5, 2017 at 4:31 AM, lily li

Re: [R] about adding a column for water year

Hardly. DF$wyear is a vector, but it is being treated as though it is a scalar. Read Bert's response. -- Sent from my phone. Please excuse my brevity. On July 4, 2017 11:17:24 AM PDT, Rui Barradas wrote: >Hello, > >You have a '{' too many. > >for(i in 1972:1985){ >

Re: [R] R and UBUNTU startup

If you want to keep your R installation up to date use the installation instructions available for ubuntu at https://cran.r-project.org/bin/linux/ubuntu/. Follow the instructions there and you will be able to use standard Ubuntu update procedures afterwards. (Delete your old version first).

Re: [R] about adding a column for water year

Hello, You have a '{' too many. for(i in 1972:1985){ if(DF$year==i & DF$month %in% 1:9){ DF$wyear <- i }else{ DF$wyear < i-1 } } } I believe this is it. Hope this helps, Rui Barradas Em 04-07-2017 19:31, lily li escreveu: Hi R users, I have a question

Thanks, it works. Yes, I got the same error message when tried my original code and Rui's code: In if (DF$year == i & DF$month %in% 1:9) { ... : the condition has length > 1 and only the first element will be used Also, I think I made a mistake, it should be i+1 rather than i-1. Otherwise, it

Well, let's see: 1) You do not appear to understand basic flow control statements in R. Note that (from ?if): if(cond) expr if(cond) cons.expr else alt.expr where "cond A length-one logical vector that is not NA." Your cond is a vector of length nrow(DF), so you don't want if, you want
