# Help on Looping

Hi I have a problem and need the help
I am trying to build a for loop in R . but facing the error as the loop is not creating the exact variable and may be double counting. Also if you can suggest efficient way of doing this.
What i trying to do is

1. I would like to develop a code which can create a variable which can sum up all the values in the column "nos" based on the filter conditions.Below are the conditions. i want to add a counter called sum (nos[i]) to sum all the rows which satisify below conditions but missing something .

The logic for less6 month calculation
library(lubridate)
dataji\$Date_Created <- as.Date(dataji\$Date_Created, "%m/%d/%Y") # convert to date
dataji\$less6month <- dataji\$Date_Created %m-% months(6) # subtract 6 months

dataji\$count <- 0 # initialise counter
i <- 1
for (i in 1:nrow(datanew1)){
compare <- (dataji\$country==dataji\$country) &
(dataji\$department==dataji\$department ) &
(dataji\$Date_Created >=dataji\$less6month[i])&
(dataji\$Date_Created <= dataji\$Date_Created[i])
dataji\$count[i] <- sum(compare)

}

structure(list(id = 1:293, nos = c(4L, 2L, 3L, 4L, 5L, 19L, 7L,
