Dear R-community, I am looking for some simple advice - I have a matrix (therefore 2 dimensional) of global temperature. Having read R-help I think that when I ask R to image() or levelplot() my matrix will it actually appear upside down - I think I therefore need to use the line:
levelplot(temperature.matrix[,ncol(output.temp):1], ........)
to get it looking like it was on the globe due to the matrix rows increasing in number down the matrix in its dimensions on longitude and latitude but the y-axis coordinates increase up the axis. Can anyone simply tell me whether this is correct as I find it very hard to know which way up my data should be and I cannot tell which is correct simply by looking at it! Many thanks for your time in reading this problem, Jenny Barnes ~~~~~~~~~~~~~~~~~~~~~~~~~~ Jennifer Barnes PhD student - long range drought prediction Climate Extremes Department of Space and Climate Physics University College London Holmbury St Mary, Dorking Surrey RH5 6NT 01483 204149 07916 139187 Web: http://climate.mssl.ucl.ac.uk
