Dear All, Thanks a lot for your help. Would you please let me know if i want to read a csv file as No, you probably need to read R basics (R-intro). I had no problem using Gabor’s code version 1 for reading directly. You obviously lack basic understanding how R works with objects. Cheers Petr zoo object from my local file rather than directly from the website, how to do that? library(zoo) u <- "https://faculty.washington.edu/ezivot/econ424/sbuxPrices.csv"; fmt <- "%m/%d/%Y" With sincere regards, Upananda Pani On Wed, Sep 20, 2017 at 3:22 PM, PIKAL Petr <petr.pi...@precheza.cz<mailto:petr.pi...@precheza.cz>> wrote: Hi Gabor's code works as expeceted without error.
