image.plot(lon, lat, tas, legend.width = 1.5, legend.shrink = 1,
legend.mar = 1, cex.axis=2,cex.lab=2,legend.cex=1.8,legend.args=list(text="K",
cex=2, side=3, line=0.5),las=1)
using above codes I get image plot but the font size of legend values is small. How to increase the font size of legend values?
