#Hello,
#I loaded data using read.table - I needed to convert a row in the data
frame to date class:

do not know how to convert 'dates[1,]' to class "Date"
# However, I can individually convert them all:
> dates1.1<-as.Date(data[1,1])
> dates1.1
[1] "2008-05-19"
# How can I change the class of the date over the entire row (my original
file contains more than one hundred rows)?
# Thank you very much.
