Rearranging Data
...indx[1]] } else { .df$date[tail(.indx, 1)] - .df$date[.indx[1]] } }) }) # output the mean and median t(sapply(out, function(.cntry) c(number=length(.cntry), mean=mean(.cntry), median=median(.cntry)))) I wanted to know if there is a way to rearrange data from IKEALASTmod so that we can use something like the code above. The new problem is that instead of date and country only, there is now date, country and product. So is it possible to rearrange my data to have the output from above be by country and price. Hope I was clear, thanks for any help you can offer!...
