我正在尝试在我的情节右侧安装第二个 ylab，但我无法获得所需的额外空间。如果不可能，在图表内绘制比例值可能是一种解决方案。我的代码（模拟数据，但右边距存在问题）：

dev.new( width= 16, height= 7 )
par( cex= 0.9 )
plot( 1:100, type="n", xlab = "", ylab = "", axes = F, las = 2, cex = 0.7 )
axis( 4, at = c ( 0, 30, 60, 90, 120, 150, 180 ), labels = c( "0", "30", "60", "90", "120", "150", "180" ), las = 0, cex.axis = .8,col.lab = "gray80",
tck = 0.01 )
rect( 153, -5.5, 169, 185, col = "gray80", border = NA)
rect( 246, -5.5, 272, 185, col = "gray80", border = NA)
lines( 1:200, col = "gray20" )
#text("Moon phase (º)", 330, 90, cex = .9 )
mtext(side = 4, text = "Moon phase (º)", line = 2, cex = .9 )
mtext(side = 1, text = "Dates", line = 4, cex = .9 )

par( new = T )
plot( 1:220, type = "n", lwd= 1.2, xlab= "", ylab= "Photoperiod (h)", axes = F, cex = .8, col.lab = "red" )
axis( side= 1, at = c ( 1, 20, 51, 82, 112, 143, 173, 204, 235, 264, 295, 324 ), labels = c ( "12 Jun'07", "1 Jul'07", "1 Aug'07", "1 Sep'07", "1 Oct'07", "1 Nov'07", "1 Dec'07", "1 Jan'08", "1 Feb'08", "1 Mar'08", "1 Apr'08", "30 Apr'08" ), las = 2, cex.axis = .75 )
axis ( side = 2, at = c( 12, 13, 14, 15, 16 ), labels = c( "12", "13", "14", "15", "16" ), cex.axis = .8, las = 2)
box()

感谢您的帮助，

见参数mar。par这会设置绘图区域的边距（底部、左侧、顶部、右侧；详情请参阅?par）。

dev.new( width= 16, height= 7 )
## set outer margins
par( mar=c(5, 4, 4, 4), cex= 0.9 )
plot( 1:100, type="n", xlab = "", ylab = "", axes = F, las = 2, cex = 0.7 )
axis( 4, at = c ( 0, 30, 60, 90, 120, 150, 180 ), labels = c( "0", "30", "60", "90", "120", "150", "180" ), las = 0, cex.axis = .8,col.lab = "gray80",
tck = 0.01 )
rect( 153, -5.5, 169, 185, col = "gray80", border = NA)
rect( 246, -5.5, 272, 185, col = "gray80", border = NA)
lines( 1:200, col = "gray20" )
#text("Moon phase (º)", 330, 90, cex = .9 )
mtext(side = 4, text = "Moon phase (º)", line = 2, cex = .9 )
mtext(side = 1, text = "Dates", line = 4, cex = .9 )

par( new = T )
plot( 1:220, type = "n", lwd= 1.2, xlab= "", ylab= "Photoperiod (h)", axes = F, cex = .8, col.lab = "red" )
axis( side= 1, at = c ( 1, 20, 51, 82, 112, 143, 173, 204, 235, 264, 295, 324 ), labels = c ( "12 Jun'07", "1 Jul'07", "1 Aug'07", "1 Sep'07", "1 Oct'07", "1 Nov'07", "1 Dec'07", "1 Jan'08", "1 Feb'08", "1 Mar'08", "1 Apr'08", "30 Apr'08" ), las = 2, cex.axis = .75 )
axis ( side = 2, at = c( 12, 13, 14, 15, 16 ), labels = c( "12", "13", "14", "15", "16" ), cex.axis = .8, las = 2)
box()

在您的代码中使用第 #2 行：

par( cex= 0.9,mar=c(6,4,6,4) )
