You could take a look at the irregular time-series (its) package
on CRAN. Your series is certainly irregular, and possibly a little
er... sparse. Anyway, the following might get you started:
require(its)
mydates <-
c("28.8.1962","27.6.1977","19.7.1989","26.6.1995","26.7.1999")
data <- matrix(1:5,dimnames=list(mydates,NULL))
its.format("%d.%m.%Y")
its(data)
