Re: [R-sig-eco] Export Google Maps Route to R and get kilometers coordinates

Hi everyone, May bei t would be more simple to use function: identify(x = coordinates(coordinate object argument)[, 1], y = coordinates(coordinate object argument)[, 2], labels = Whatever) You would only need to click next to the points of interest to make the coordinates appear.

Hi Justine, Which formula are you talking about? I have scripted many hydraulic algorithms and am familiar with your issue although I used other ADCP softwares. The data looks all right to me. Please do specify more in detail what your challenge is in order to report this data. So far, I've

Dear Mauricio, I would confirm the use of rgdal::spTransform as appropriate. Also, one could add creating a CRS database as follows: #European Petroleum Survey Group list creation EPSG - make_EPSG() The geographical ETRS89 CRS is then the following I believe: #ETRS89 (= EUREF89 = GRS80)

Hi Stacy, To start simple, a loop is written as follows in R: For (i in 1 : x){ } If by ranking, you mean ordering data, than you can use package chron to create time objects that are to my opinion practical to use. If by ranking you meant classifying your data in function of tide classes,

Hi Stacey, How we meet again... You could re-project your data by using package sp with function: spTransform The only thing you need is to define the coordinate reference system of your input spatial object when creating it using the input projection-less shapefile and then to define the
