Mark,
Below is the sampled simulated granular data format for pumps for
trial period of 3 months that I need to transform for survival
analysis:
3 months = (60*24*90) minutes i.e 129600 minutes
pump_id timingsevents vibration temprature flow
pump1 01-07-2017 00:00 0
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 t

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)

Hardly. DF$wyear is a vector, but it is being treated as though it is a scalar.
Read Bert's response.

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). Downl
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,

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 h

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 ife

Thanks Boris and Bret,
I was successful in simulating granular/transactional data.
Now I need some guidance to transform the same data in format acceptable
for survival analysis i.e below format:
pump_id | event_episode_no. | event(0/1) | start | stop | time_to_dropout
The challenge I'm experienc
Thanks,
I will try.
Best regards.

Q1. No.
Q2. What do you do? Did you follow the instructions at [1]? If you go to the
top level of the R help system you should be able to open the manuals. ?help
Q3. Not that I know of. If you have difficulty with R on Linux then you should
focus on learning how to use Linux in general... and
I did the same transition, facing the same issues, so I settled for
installation of RKWard. This pretty much reproduces my previous experience with
Tinn-R and the Rgui.
