...ith origin=1900-1-1 the dates that R reported me where two days ahead than the ones I read from Excel. I noticed that when I did in R the following: > as.Date("2011-3-4")-as.Date("1900-1-1") Time difference of 40604 days but if I do the same operation in Excel the answer is 40605. Does anybody know what can be going on? Thank you Felipe Parra [[alternative HTML version deleted]]
