Dear Users of R, I have this following confusion. Some months ago I use to download 3 hourly TRMM data from NASA website by using the R from the following website http://giovanni.gsfc.nasa.gov/giovanni/#service=ArAvTs&starttime=2008-12-31T00:00:00Z&endtime=2009-12-31T23:59:59Z&bbox=67,-50,67,-50&data=TRMM_3B42_007_precipitation bbox=67,-50,67,-50 show the point where I want to download the data in the form of CSV file. The problem is that I have a vector of such points, a small of which is below structure(c(72, 71, 54, 67, 50, 53, 30, -50), .Dim = c(4L, 2L), .Dimnames = list(c("d", "e", "f", "g"), NULL)) How can I make a loop to download the data on given points automatically? Thankyou very much in advance. Eliza [[alternative HTML version deleted]]
