Hi Jim, I tried, dat2<-as.Date(dat1,format="%Y-%V")
dat2
[1] "1951-07-02" "1952-07-02" But, if the format is for YYYY-wk or YYYY-yy, then, not sure how this will help.

In order to do any conversion, you have to know the format of the data that is being input. So which is it: does 52 represent the day of the year, or the week of the year? Does make a big difference, but until you know what "1952-52" means, it is hard to specify which way you should do the conversion.
