This post will show an easy way to use cut and ggplot2‘s stat_summary to plot month totals in R without needing to reorganize the data into a second data frame.
Here is a simple way to do it:
mydata<data.frame(NO_Empl=c(127,125,124),Month=c(9,8,7),Year=c(2017,2018,2017)) library(lubridate) library(tidyverse) as.tibble(mydata) %>% mutate(Date=make_date(Year,Month)) %>% select(Month,Year) %>% mutate(Day=wday(Date),Day_date=month(Date))
The result:
# A tibble: 3 x 4 NO_Empl Date Day Day_date <dbl> <date> <dbl> <dbl> 1 127 20170901 6 9 2 125 20180801 4 8 3 124 20170701 7 7

 It gave below result: NO_OF_EMPLOYMENT Month Year day 1 127.24 9 2017 1 2 127.24 9 2017 2 3 127.24 9 2017 3 4 127.24 9 2017 4 5 127.24 9 2017 5 6 127.24 9 2017 6 7 127.24 9 2017 7 8 127.24 9 2017 8 9 127.06 10 2017 1 10 127.06 10 2017 2 It was going till Day 8 only . I guess it is taking the total months:8 and giving sequence till that.
 This worked for me: emp_data < emp_data%>%uncount(weights = days_in_month(as.Date(str_c(Year,"",Month,"",1))),.id="Day").... Thank you so much :)
