Hello,
Try
as.Date("01OCT1928", format="%d%b%Y")
[1] "1928-10-01"
Note that though probably not a problem to you, this is locale specific.
In Portugal, the string corresponding to the same date would be
"01OUT1928". The variable to set using Sys.setlocale() would be LC_TIME.
For date formats the help page you want is
help("strptime")
?strptime
Hope this helps,
Rui Barradas

Hi,
I imported an excel table (using read.csv) of Dow Jones monthly average
closings where the first variable is a date as a character string such
as "01OCT1928". How do I convert this to a date variable so I can plot
monthly average closings against date using ggplot2?
Thanks,
Walt
