search for: 36x72

Hi useR's I have created a simple map of the world using the following code: m <- map(xlim=c(-180,180), ylim=c(-90,90)) map.axes() I then create a grid of dimension 36x72 using the code: map.grid(m, nx=72, ny=36, labels=FALSE, col="black") This gives 2592 grid cells. In a separate data set of dimension 36x72, I have 2592 temperature values (some missing values are present) ranging from -20 degrees F to 90 degrees F. My question is, how can I create a...

...4.49 29.83 2 and this goes on for a A LOT more records, until time=1200 I want to create a 5 degree by 5 degree grid of this data, with the value of temperature in the appropriate grid cell. I want one grid for each time value. For each time value, this works out to be a 36x72 grid with 2592 cells because the longitude spans -180 to 180 and latitude spans 90 to -90 and they would be in increments of 5 degrees. If there are no temperatures available to be put into a grid cell, than that cell should get a missing value, NA, put into it. Also, could the gridded result for...
