Different character types of same column into date format

[Mouni]

I have an excel file with columns Date_of_visit & As_of_date and 2 rows. While I'm loading into data frame one row is in date format and another in numeric. I want to format the column into same format.

I'm trying the below code with no luck

    df$Date_of_visit <- as.Date(as.numeric(df$Date_of_visit), origin = "1899-12-30")
    df$As_of_date <- as.Date(as.numeric(df$As_of_date), origin = "1899-12-30")

Output :

I'm struggling with this from 2 days. Please help me out.

Many thanks,
Mouni

Hi,

Could you please create a reprex to provide us with some of the data you are working with and what you are trying to do to it. A reprex consists of the minimal code and data needed to recreate the issue/question you're having. You can find instructions how to build and share one here:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

My first idea would be to use the date formatting function on the strings like this

myData = data.frame(date = c("16/01/2020", "01/05/2020"))
myData$date = as.Date(myData$date, format = "%d/%m/%Y")

class(myData$date)
#> [1] "Date"
myData$date
#> [1] "2020-01-16" "2020-05-01"
