如何创建包含多行文本和数学表达式的图例标签,使其在单独的一行上,同时避免以下问题?
这里接受的答案对于图例不起作用,而我所知道的,涉及bquote的备选答案也不适用于我的情况,如下所示。
可重现代码:
# multiple lines in first legend label are not horizontally aligned
# also, entire legend label is not vertically aligned with box
plot( runif(10), runif(10) )
legend( x='top', fill=grey.colors(2), bty='n', ncol=2, inset=.1,
legend=c( expression( "Hello world\nGoodbye world\n" ~ 64 %/% 8 %/% 8 ),
'something else' ) )
# both above problems fixed, but math expression doesn't display right
plot( runif(10), runif(10) )
legend( x='top', fill=grey.colors(2), bty='n', ncol=2, inset=.1,
legend=c( paste( "Hello world\nGoodbye world\n", expression( 64 %/% 8 %/% 8 ) ),
'something else' ) )
# nested atops within bquote almost works in title, but font size is not uniform
# does not work at all in legend, anyway
plot( runif(10), runif(10) )
label1 = bquote( atop( atop( "Hello world", "Goodbye world" ), 64 %/% 8 %/% 8 ) )
labels = c( label1, 'something else' )
title( label1 )
legend( x='top', fill=grey.colors(2), bty='n', ncol=2, inset=.1, legend=labels )
