Hello, I am trying to use HMisc describe on a data frame. I have specified certain variables as dates using, for example:
df1$aidsdate <- dates(aidsdate,format="day.mon.year", origin=c(month = 1, day = 1, year = 1960)) When I use describe on the dataframe I get this error: Error in Ops.dates(weights, x) : * not defined for chron objects Has anyone had this problem? I had used the same method with an older version of R and HMisc and it worked. Should be be formatting date variables differently? Thank you!
