My data looks like this for one column:
Date AED.USD
03/01/2005 3.6726
04/01/2005 3.6726
05/01/2005 3.6725
06/01/2005 3.6726
07/01/2005 3.6725
08/01/2005 NA
09/01/2005 NA
10/01/2005 3.6726
11/01/2005 3.6725
12/01/2005 3.6726
13/01/2005 3.6725
14/01/2005 3.6726
15/01/2005 NA
16/01/2005 NA
17/01/2005 3.6725
18/01/2005 3.6726
19/01/2005 3.6725
20/01/2005 3.6725
21/01/2005 3.6725
I want to remove the dates with the weekends, I have tried using
x <- seq(as.Date("2005-01-03"),as.Date("2016-11-30"),by = 1)
x <- fxdl_weekdays[!weekdays(x) %in% c('Saturday','Sunday')]
this shows the dates in the values section but how am I supposed to show this in an updated data frame.
回答1:
df[which(weekdays(as.Date(df$Date, format = "%m/%d/%Y"))
%in% c('Monday','Tuesday', 'Wednesday', 'Thursday', 'Friday')), ]
