Converting year and month ("yyyy-mm" format) to a date?
(9 answers)
Closed 2 years ago.
I have date in character vector. I need to convert it to date format.
For example :
Month = "202005"
Output should be May-20. It should be in date format so that I can use to filter some dates. Similarly 201912 should return Dec-19
zoo has a function called yearmon().
library(zoo)
month <- "202005"
as.yearmon(month, "%Y%m")
# "May 2020"

For my dataset, the Date variable has dates in the format of this example: 19-Feb-03
I want to change the above character format dates in the column to a Date format. (As I have to do time series analysis later on)
I tried using the as.Date() method but it didn't work.
x <- '19-Feb-03'
lubridate::ymd(x)
"2019-02-03"
Not sure whether 19 is year or day. You can try lubridate package
x<-"19-Feb-03"
library(lubridate)
ymd(x)
dmy(x)

I currently have a database with dates in character format yyyy-mm format. e.g. 2009-01 and missing values.
I'm struggling to convert this into a date format.
You could use ym from lubridate package:
lubridate::ym('2009-01')
#[1] "2009-01-01"

I have a column with date in the format 20201020 (AAAAMMDD) as integer and a need to format as date 2020-10-20.
I`ve tried:
as.Date(MYDATE, format = "%m/%d/%y", origin = "1900-01-01")
AND
format(MYDATE, "%m/%d/%Y")
But returned just
NA
Using lubridate we can:
ymd(MY_DATE)

I have integer data example like this
201901, 201912, 202004
How to convert my data into year and month using R Programming. I need output like this:
2019-01, 2019-12, 2020-04
or
Jan-2019, Dec-2019, Apr-2020
Thank you in advance.
You can convert to date and then use format :
x <- c(201901, 201912, 202004)
format(as.Date(paste(x, '01'), '%Y%m%d'), '%b-%Y')
#[1] "Jan-2019" "Dec-2019" "Apr-2020"
format(as.Date(paste(x, '01'), '%Y%m%d'), '%Y-%m')
#[1] "2019-01" "2019-12" "2020-04"
You can also use zoo's yearmon :
zoo::as.yearmon(as.character(x), '%Y%m')
Using regex we can capture 4 and 2 characters and insert a "-" in between.
sub('(.{4})(.{2})', '\\1-\\2', x)

I want to convert mmm-yy(Jan-85) date format into yyyy-mm-dd (1985-01-02)date format in R.
One option is to paste the day and convert it to Date class with as.Date and the appropriate format
as.Date(paste0("Jan-85", "-02"), "%b-%y-%d")
#[1] "1985-01-02"
