Dear R users,
I know, the question is bit old one. :-(
Ok. I have a table with say three columns and 70 rows.
The second column has dates in format dd.mm.yy (i.e. 01.10.07 indicating
record for October 1, 2007).
I read the text file, containing the records. Now, I want to find out the
weekday for each date.
However, I cannot do so.
1)
If I type result[1,"Date"] to see the Date in the first row, I get following
output:
70 Levels: 01.10.07 01.11.07 02.10.07 02.12.07.. and so on.
2)
If I use any functions related to Date or time, I get the message: character
string is not in a standard unambigious format.
:-(
I can understand that first I have to "convert" the existing date format to
such a format that R "recognizes" as date format. However, I am not able to
do so.
I did try to use format.Date() and as.Date() functions. However, no success.
I am making some silly mistake.
Please help.
If you want Date rather than some posic format, use
newDate <- as.Date(result[,"Date"], "%d.%m.%y"))

Thank you.
