Re: [R] operating website through R
This looks not so elegant, while normally data provider must have a nice accessing API, anyway, for example you can do this: myAdd - 'http://disc2.nascom.nasa.gov/daac-bin/Giovanni/tovas/Giovanni_cgi.pl?west=60north=50east=70south=-50params=0|3B42_V7plot_type=Area+Plotbyr=2014bmo=01bdy=31eyr=2014emo=01edy=31begin_date=1998%2F01%2F01end_date=2014%2F01%2F31cbar=cdyncmin=cmax=yaxis=ydynymin=ymax=yint=ascres=0.25x0.25global_cfg=tovas.global.cfg.plinstance_id=TRMM_V7prod_id=3B42_dailyaction=ASCII+Output' myData - read.table(myAdd, skip=5, header=T) Will give you this: str(myData) 'data.frame':16441 obs. of 3 variables: $ Latitude : num -50 -50 -50 -50 -50 -50 -50 -50 -50 -50 ... $ Longitude: num 60 60.2 60.5 60.8 61 ... $ AccRain : num 0 0.42 0.39 0.42 0.66 1.23 2.31 2.37 3.72 3.63 ... For choosing different parameters, for example in case of coordinates, you just need to change the values in 'myAdd' parameters after Giovanni_cgi.pl?, west, north, east, south. But you must be sure that there is a data available with those parameters, no magical error control here.
