我试图为 4 个组合子图设置一个通用标题和一个唯一的通用 xy 轴标签:
dev.new( width = 9, height = 10)
layout( matrix( c( 0, 1, 1, 2, 3, 4, 2, 5, 6, 0, 7, 7 ), 4, 3, byrow = TRUE), widths = c( 1, 4, 4 ), heights = c( 1, 4, 4, 1 ) )
par( mar = c( 1, 0, 1, 0 ) )
plot( c(1:2), type = "n", xlab = "", ylab = "", axes = F, cex = 0.7 ) #general title
title( main = "title", ps = 2 )
par( mar = c( 1, 0, 1, 1) )
plot( c(1:2), type = "n", xlab = "", ylab = "", axes = F, las = 2, cex = 0.7 ) #general y-label
title( main = " y-label ", las = 0 )
par( cex= 0.9, mar = c( 5, 1, 1, 2 ) )
plot( c(1:10), type="l", xlab = "A", ylab = "", axes = T, las = 1, cex = 0.7 ) # first subplot
par( cex= 0.9, mar = c( 5, 1, 1, 3 ) )
plot( c(10:1), type ="l", xlab = "B", ylab = "", axes = T, las = 1, cex = 0.7 ) # second subplot
par( cex= 0.9, mar = c( 5, 1, 1, 2 ) )
plot( c(1:10), type="l", xlab = "C", ylab = "", axes = T, las = 1, cex = 0.7 ) # third subplot
par( cex= 0.9, mar = c( 5, 1, 1, 3 ) )
plot( c(1:2), type="l", xlab = "D", ylab = "", axes = T, las = 1, cex = 0.7 ) # fourth subplot
par(mar = c( 1, 0, 1, 0 ) )
plot( c(1:2), type = "n", xlab = "", ylab = "", axes = F, cex = 0.7 ) #general x-label
title( main = " x-label " )
如何控制这些标题的字体大小、位置和方向?
