Please note that I have already asked this question on stackoverflow.com but
did not get a satisfactory answer. I have a data set containing velocities of
2169 vehicles recorded at
intervals of 0.1 seconds. So, there are many rows for an individual
vehicle. Here I am reproducing the data only f
t so not all vehicles had svel==0. The vehicles which
did stop didn't do it at the same time. Also, the number of rows in which
svel==0 is different vehicle to vehicle.
Thanks,

I have a data frame of vehicle trajectories. Here's a snapshot:
>dput(head(df))structure(list(vehicle = c(2L, 2L, 2L, 2L, 2L, 2L), frame =
>43:48, globalx = c(6451214.156, 6451216.824, 6451219.616, 6451222.548,
>6451225.462, 6451228.376), class = c(2L, 2L, 2L, 2L, 2L, 2L), velocity =
Hello everyone,Here is the version using dput. I am sorry for the junk I posted
before. I have a large vehicle trajectory data of which following is a small
part:
structure(list(vehicle = c(1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L,2L, 2L), frame =
c(221L, 222L, 223L, 224L, 115L, 116L, 117L, 118L, 11
al data I found 22 as min and 9233 as max frame number.
> This makes 30 time slots as 22-322, 322-622, ..., 9022-9233. I need following
> output:
TimeSlot Total-Cars Total-Trucks Total-Motorcycles MeanVelocity-Cars
MeanVelocity-Trucks MeanVelocity-Motorcycles22-322322-622...9022-9233
I have tried many things and also used some suggestions from stackoverflow but
still am unable to get output like this with input data. Please help.

t;,
fixedBreaks = 4.5) :
variable range greater than fixedBreaksEven after intervals are created, I
need to group spacing and find the avg. for every interval. How can I do this?
