我想在fill.contour()圖中減少邊距,但以下任一代碼均失敗。控制filled.contour()保證金?
par(mar=c(0,0,0,0))
png(filename="Sec_B11_112.png",width=7000,height=5000,res=1000)
filled.contour(diff51,zlim=c(-0.11,0.16),xlab=expression(T[1]),ylab=expression(T[2]))
dev.off()
png(filename="Sec_B11_112.png",width=parwd,height=parht,res=parres)
filled.contour(diff51,zlim=c(-0.11,0.16),xlab=expression(T[1]),ylab=expression(T[2]),par(mar=c(0,0,0,0))
dev.off()
我該怎麼做?
