[R-sig-Geo] How do i plot a graph with x axis vertically labelled?

[Vasana Tutjavi]

Dear R-sig-geo experts, 

I want to plot a bar graph with the labels on the x axis in a vertical format. The data is the Ages of Squid (on the Y axis) and the date of Birth on the X axis, I am struggling to change the labels on the x axis to a vertical format and I want all the dates to show at all the bars. My data is as follows:
Birth

Here is the script I tried:

barplot(Females2005$Age,  names.arg = c("25/08/2004", "26/09/2004", "02/11/2004", "11/11/2004", "22/11/2004", "04/12/2004", "08/12/2004", 
                                       "15/12/2004", "21/12/2004", "24/12/2004", "04/01/2005", "06/01/2005", "13/01/2005", "18/01/2005",
                                       "19/01/2005", "09/02/2005", "11/02/2005", "13/02/2005", "17/02/2005", "18/02/2005", "19/02/2005", 
                                      "24/02/2005", "28/02/2005", "01/03/2005", "07/03/2005", "08/03/2005", "09/03/2005", "14/03/2005", 
                                    "16/03/2005", "25/03/2005", "01/04/2005", "06/04/2005", "07/04/2005", "08/04/2005", "13/04/2005", 
                                      "14/04/2005", "27/04/2005", "01/05/2005", "07/05/2005", "08/05/2005", "16/05/2005", "30/05/2005", 
                                    "06/06/2005"), main = 'Females 2005', ylab = 'Age/Days', xlab = 'Birth/Hatch date')

Many thanks
