Convert Date in R

I have used the internet and tried different options but not able to convert the string to date format

Sample Values in my data frame named as A in vector date

Date  
"1-Sep"  
"2-Sep"  
"3-Sep"  
"4-Sep"  
"5-Sep"  
"6-Sep"


x<-A$Date
A$Date_2<-as.POSIXct(paste("01-", x, sep = ""), format = "%d-%b-%y")

I want the output in "2020-09-28" format

We can use dmy

library(lubridate)
A$Date_2 <- dmy(A$V1, truncated = 2)
A$Date_2
#[1] "2020-09-01" "2020-09-02" "2020-09-03" "2020-09-04" "2020-09-05" "2020-09-06"

data

A <- structure(list(V1 = c("1-Sep", "2-Sep", "3-Sep", "4-Sep", "5-Sep", 
"6-Sep")), row.names = c(NA, -6L), class = "data.frame")

Try this. Maybe you need to add the year as it looks like you have day and month in your strings. Then, you can use as.Date() function:

#Code
A$Date_2<-as.Date(paste("2020-", x, sep = ""), format = "%Y-%d-%B")

Output:

     V1     Date_2
1 1-Sep 2020-09-01
2 2-Sep 2020-09-02
3 3-Sep 2020-09-03
4 4-Sep 2020-09-04
5 5-Sep 2020-09-05
6 6-Sep 2020-09-06

Some data used:

#Data
A <- structure(list(V1 = c("1-Sep", "2-Sep", "3-Sep", "4-Sep", "5-Sep", 
"6-Sep")), row.names = c(NA, -6L), class = "data.frame")
