Generate alternate saturday dates list within range in R
$begingroup$
library(tidyr)
d = seq(as.Date("2018-01-01"),Sys.Date()+365,by='day')
saturdayList = d[weekdays(d)=='Saturday']
altSaturdayList = data.frame(lapply(split(saturdayList, format(saturdayList, "%Y-%m")), function(x)
na.omit(x[c(2,4)])))
altSaturdayList = subset(gather(altSaturdayList),select = c(value))
HolidayList = rbind(HolidayList, setNames(altSaturdayList, "Holidays"))
HolidayList = rbind(HolidayList, setNames(as.data.frame(as.Date("2018-11-06")), "Holidays"))
HolidayList = arrange(unique(HolidayList),Holidays)
rm(d)
rm(saturdayList)
rm(altSaturdayList)
The above code generates a list of dates which contain 2nd and 4th saturday of every month within that date range.
As you can tell I have generated and deleted intermediate variables like d
, saturdayList
and altSaturdayList
. I was wondering how I can make this code better and efficient?
I learned about %>%
operator but I don't know how I can do it with no input.
Any tips to improve the code is welcomed. Thanks
