as.Date function error
Hi,
I have some problems with as.Date function.
After I applied as.Date for my data, "2010" changed to "2020" as below
Where am I wrong?
Thanks

How to convert 3-digits hours
...s what I try to do.
> strptime('20110101 0900',"%Y%m%d %H%M")
[1] "2011-01-01 09:00:00"
> strptime('20110101 900',"%Y%m%d %H%M")

If I have a 3-digit hour like '900', please show me how to convert it to 9:00:00.
Thank you in advance.

Conversion to xlsx file
Hi, all
I would like to convert xls files to xlsx files with R commands in R console
instead of saving xls files as xlsx files after opening xls files.
Please show me how.
Thanks.
