I have a dataframe (df3) with with some values.
One of these values is the daedlines.
The data of this value is something like the following:
deadline
1419397140
1418994978
1419984000
1418702400
They are days and I want to convert the to using this:
df3$deadline <- as.POSIXct(df3$deadline, origin="1970-01-01")
Generally it was worked for me with other dataframes from other files.
However with this it gives me back this error:
Error in as.POSIXlt.character(as.character(x), ...) :
character string is not in a standard unambiguous format
How can I fix it?
It might be that you have a character or factor, and it's expecting a numeric vector for conversion from unix time :
as.POSIXct(as.numeric(as.character(df3$deadline)),origin="1970-01-01")
