It is easier with the other data.frame you had with:

       labels   starts     ends
1  first task 1-Jan-04 3-Mar-04

and as.Date see
?as.Date

e.g.
as.Date("1-Jan-04","%d-%b-%y")
or for the whole column:

myframe$starts<-as.Date(myframe$starts,"%d-%b-%y")

now I hope you have learnt how to get the data into a list for the
gantt.chart...
