Hi,
That eir$date might be a factor is irrelevant. There is an as.Date() method for
factors, which does the factor to character coercion internally and then calls
as.Date.character() on the result.
Using the example data below:
eir <- data.frame(date = c("05-30-16", "05-30-16",
"05-30-16",
"05-30-16", "05-30-16",
"05-30-16"))
> str(eir)
'data.frame': 6 obs. of 1 variable:
$ date: Factor w/ 1 level "05-30-16": 1 1 1 1 1 1
> eir
date
1 05-30-16
2 05-30-16
3 05-30-16
4 05-30-16
5 05-30-16
6 05-30-16
eir$date <- as.Date(eir$date, format = "%m-%d-%y")
> str(eir)
'data.frame': 6 obs. of 1 variable:
$ date: Date, format: "2016-05-30" ...
> eir
date
1 2016-05-30
2 2016-05-30
3 2016-05-30
4 2016-05-30
5 2016-05-30
6 2016-05-30
eir$days <- weekdays(eir$date)
> str(eir)
'data.frame': 6 obs. of 2 variables:
$ date: Date, format: "2016-05-30" ...
$ days: chr "Monday" "Monday" "Monday"
"Monday" ...
> eir
date days
1 2016-05-30 Monday
2 2016-05-30 Monday
3 2016-05-30 Monday
4 2016-05-30 Monday
5 2016-05-30 Monday
6 2016-05-30 Monday
I would check to be sure that you do not have any typos in your code.

Thanks Marc for the help. this really helps. I think there is some issue with the data saved in csv format for this variable as when i checked: str(eir$date)- this results in :- Date[1:5327], format: NA NA NA NA NA. Thanks again.

Show us the output, don?t just tell us what you are seeing. If the dates are correct in the csv file, show us the structure of the data frame you created with read.csv() and show the command(s) you used to convert the character data to date format. The solution is likely to be simple if you will cut/paste the R console and not just describe what is happening.

Hi David please see the code and some reproducible data:
eir$date<- as.Date(eir$date,format = "%m-%d-%y") then i had used
the
lubridate library to help with the dates:
install.packages("lubridate")
library(lubridate)
eir$date <- mdy(eir$date)
weekdays <- wdy(eir$date)
week names <- wdy(eir$date, label = TRUE)
This the output from the file:
structure(list(date = structure(c(NA_real_, NA_real_, NA_real_), class
"Date"),
month = structure(c(2L, 2L, 2L), .Label = c("Jun","May"),
class = "factor"),
day = c(30L, 30L, 30L),
weekday = structure(c(2L,2L, 2L), .Label = c("Fri", "Mon",
"Sat", "Sun",
"Thu", "Tue","Wed"), class = "factor"),
survey_rating = c(3L, 2L, 3L), query_status = c("Yes", "Don't
know","No"),
a = c("05-30-16", "05-30-16", "05-30-16")),
.Names = c("date","month",
"day", "weekday", "survey_rating"), row.names =
c(NA, 3L), class "data.frame")
There are several other variables that i have removed which are not
relevant in this context.
