Cheers Jim!
The 0/1 way seems to work for me. It looks like:
n <- 5 # number of ?shops?
i <- 12 # number of time intervals per hour
# creating a data.frame (the example got random values)
business_hours <- data.frame(1:n, matrix(data = sample(x = c(TRUE, FALSE), size = n * (24 * i), replace = TRUE), ncol = 24 * i))
# column names as the times
colnames(x = business_hours) <- c("Id", paste0("t", sprintf(fmt = "%02d", rep(x = 0:23, each = i)), sprintf(fmt = "%02d", rep(x = seq(from = 0, to = 60/i * (i - 1), by = 60/i), times = 24))))
# some data analysis
plot(x = colSums(x = business_hours[, -1]), type = "s") # looks odd due to the random assignment of open/closed
summary(object = rowSums(x = business_hours[, -1])/i) # summary of business duration in hours
Best regards,
Alex
