Extract time and state of charge (Start and End) and Count
Dear all, This is the desired expected output: State of Charge (start_end SOC) Hour 0-12 1-12 2-12 3-12 4-12 5-12 6-12 7-12 8-12 9-12 10-12 11-12 12-12 0 1 2 ? 20 21 22 23 On Tue, Jul 19, 2022 at 10:46 AM roslinazairimah zakaria <

Thank you so much Avi, Rui and Jim...really appreciate your help.
I am so sorry for not able to make it clearly.
This is the expected output:
Hour Starting_SoC_of_12 Ending_SoC_of_12 frequency
0 0 12
603
1 1 12
136
dt <- dt3[which(dt3$Year==2014),]
head(dt); tail(dt)
dput(dt[1:5000,])
cols <- c("BatteryChargeStartDate", "BatteryChargeStopDate")
dt[cols] <- lapply(dt[cols], \(x) sub("\n", " ", x))
# use package lubridate to coerce to a datetime class
dt[cols] <- lapply(dt[cols], lubridate::dmy_hm)
h <- lubridate::hour(dt[["BatteryChargeStartDate"]])
aggregate(Starting_SoC_of_12 ~ h, dt, length)
Expected output:
Hour Starting_SoC_of_12 Ending_SoC_of_12 frequency
0 0 12 603
1 1 12 136

Dear all, I have data of Battery Electric vehicle (BEV). I would like to extract data from every hour starting from 0.00 to 0.59, 1:00-1:59 for SOC(state of charge) start to end. Some examples: I can extract data from SOC=0 and SOC=12 dt_2014[which(dt_2014$Starting_SoC_of_12==0 & dt_2014$Ending_SoC_of_12==12),] I can extract data from SOC=1 and SOC=12 dt_2014[which(dt_2014$Starting_SoC_of_12==1 & dt_2014$Ending_SoC_of_12==12),] and I would like to further categorise the data by hour and count how many cars from 0 state charge to 12 state charge at in that particular hour.
