I have some data set which has latitude, longitude and Z values.
I would like to plot them on global map.
I am thinking to use image
image(x, y, z, zlim, xlim, ylim, col = heat.colors(12),
add = FALSE, xaxs = "i", yaxs = "i", xlab, ylab,
breaks, oldstyle = FALSE, useRaster = FALSE, ...)
here I have x = longitude
y= latitude
z = z
but z suppose to be matrix but my z values are single array , could
somebody please tell me how to convert these single array of z to matrix ?
