It would be easy with lubridate, where we convert the strings in hm format and divide by 15 minutes.

library(lubridate)
(hm(a) - hm(b))/minutes(15)
#[1] 8

data

a <- "08:00"
b <- "06:00"

Something like this using difftime?

difftime(
    as.POSIXct("08:00", format = "%H:%M"), 
    as.POSIXct("06:00", format = "%H:%M"), 
    units = "mins") / 15
#Time difference of 8 mins

Or to convert to numeric

as.numeric(
    difftime(as.POSIXct("08:00", format = "%H:%M"), 
    as.POSIXct("06:00", format = "%H:%M"), 
    units = "mins") / 15)
#[1] 8
